Description

Hair cosmetics

The present invention relates to a cosmetic composition that does not contain silicones, and is used as a hair cosmetic composition for use as a hair rinse, hair conditioner, hair treatment, hair mask, etc., or an oil-based hair cosmetic composition for use as a hair oil, hair wax, etc.

In cosmetics, silicones provide excellent usability such as a slippery feeling and a smooth and light feeling to the skin and hair, and are also excellent in the effect of improving luster, and therefore have been widely used in a wide range of applications such as skin care, hair care, makeup, and sun care. In particular, in the field of hair care, silicones are highly valued as essential ingredients in in-bath products such as shampoos and hair rinses used after washing hair, hair conditioners, and hair treatments. They are also highly valued as essential ingredients in out-bath products such as hair oils and hair waxes.
However, in recent years, due to consumer preference for natural materials and consideration of environmental impact, there has been a demand for the development of cosmetics that do not contain silicones, in particular cosmetics for hair care that do not contain silicones.

Against this background, various substitutes for silicones (hereinafter also referred to as "non-silicone compounds") have been developed, and cosmetics that contain these non-silicone compounds but do not contain silicones have been proposed (Patent Documents 1 and 2). However, no cosmetics containing non-silicone compounds have been developed that have the same effects as the excellent feel of use obtained by the incorporation of silicones, for example, hair cosmetics that have a sufficiently equivalent hair conditioning effect.

JP 2016-222731 A JP 2020-002056 A

The present invention aims to provide hair cosmetics such as hair rinses, hair conditioners, hair treatments, and hair masks, or oil-based hair cosmetics such as hair oils and hair waxes, which do not use silicones but instead incorporate non-silicone compounds, and which have the same or better effects as those that incorporate silicones, for example the same or better usability.

As a result of extensive investigation, the present inventors have found that
In hair cosmetics for in-bath products such as hair rinses, hair conditioners, hair treatments, hair shampoos, rinse-in shampoos, and hair masks, by blending glyceryl (diisostearate/hydrogenated rosin acid), a specific cationic surfactant, and a higher alcohol, it is possible to obtain excellent effects, such as excellent usability, equivalent to or superior to those obtained when silicones are blended, without blending silicones, and
The inventors have found that by blending a fatty acid triglyceride, such as glyceryl (diisostearate/hydrogenated rosin acid), and other oils other than the fatty acid triglycerides, in oil-based hair cosmetics such as hair oils and hair waxes, it is possible to obtain excellent effects equal to or greater than those obtained when silicones are blended, even without blending silicones, and have completed the present invention.

The first aspect of the present invention is
The present invention relates to a hair cosmetic composition for in-bath use, the hair cosmetic composition being characterized in that it contains (1) glyceryl (diisostearate/hydrogenated rosin acid), (2) a tertiary amine-type cationic surfactant and/or a quaternary ammonium salt-type cationic surfactant, (3) a higher alcohol, and (4) water (hereinafter, also referred to as hair cosmetic composition 1 of the present invention).

The second aspect of the present invention is
The oily hair cosmetic composition according to the present invention is characterized in that it contains (12) a fatty acid triglyceride, and (22) an oil other than the fatty acid triglyceride (hereinafter, also referred to as hair cosmetic composition 2 of the present invention).

Hair cosmetic preparation 1 of the present invention, even without silicones, has excellent usability such as moisturizing, smoothness, and silky feel equivalent to or better than hair cosmetic preparations containing silicones with low or high degrees of polymerization or amino-modified silicones, and further has the effect of improving combability of hair.

Hair cosmetic preparation 2 of the present invention has a feel when used that is equal to or better than that of an oil-based hair cosmetic preparation containing silicones with low or high degrees of polymerization or amino-modified silicones, even though it does not contain silicones. In other words, the combination of (12) fatty acid triglyceride and (22) an oil other than the fatty acid triglyceride exhibits an excellent silicone replacement effect.

FIG. 1 is a diagram showing combability in a wet state for hair cosmetic composition 1 of the present invention. FIG. 2 is a graph showing combability of the hair cosmetic composition 1 of the present invention when the hair is dry.

I. Hair Cosmetic Preparation 1 First, the essential components of Hair Cosmetic Preparation 1 (the above-mentioned essential components: (1), (2), (3), and (4)) will be described.

[Component (1): Glyceryl (diisostearate/hydrogenated rosin acid)]
Glyceryl (diisostearate/hydrogenated rosin acid) (component (1)), an essential ingredient of hair cosmetic preparation 1, is a triglyceride-type ester oil obtained by esterifying glyceryl diisostearate with hydrogenated rosin. It is an ester oil with excellent moisture retention properties, and is characterized by having a gloss like lanolin oil, while producing less peroxides and having less odor compared to lanolin oil. As glyceryl (diisostearate/hydrogenated rosin acid), a commercially available product such as Vistanol GDHR (product name, manufactured by Seiwa Kasei Co., Ltd.) can be used.
Rosin is an amber-colored, amorphous natural resin obtained from pine trees, and is a mixture of abietic acids, pimaric acids, etc. It has three ring structures, conjugated double bonds, and carboxyl groups, and is highly reactive, so derivatives with various functions are used as cosmetic and industrial raw materials. Among them, hydrogenated rosin is a compound that is stabilized by hydrogenating the conjugated double bonds, which are considered unstable in air.

The amount of glyceryl (diisostearate/hydrogenated rosin acid) blended can be freely selected depending on the formulation and aspect of hair cosmetic 1, but the blending ratio in the total amount of hair cosmetic 1 is preferably 0.1 to 20 mass%, more preferably 1 to 10 mass%, and even more preferably 1 to 8 mass%. If the blending amount is less than 0.1 mass%, it is difficult to fully achieve the effects of excellent usability and improved combability when used as a hair cosmetic, while blending more than 20 mass% does not provide an improvement in effect commensurate with the blending amount.

[Component (2): Tertiary amine type cationic surfactant and/or quaternary ammonium salt type cationic surfactant]
As the tertiary amine type cationic surfactant and/or quaternary ammonium salt type cationic surfactant (component (2)), which is an essential component of the hair cosmetic preparation 1, the same surfactants as those used in general hair rinse or hair conditioner-based preparations can be used.

An example of a tertiary amine cationic surfactant is a tertiary amine compound represented by the following formula (I):

[In the formula, R ¹ is a linear or branched alkyl or alkenyl group having 6 to 24 carbon atoms, A is an ester group, an amide group, or an ether group, m representing the number of As is 0 or 1, R ² is a linear or branched alkylene or alkenylene group having 1 to 6 carbon atoms, and R ³ and R ⁴ are the same or different and each is a hydrogen atom or a linear or branched alkyl group having 1 to 6 carbon atoms.]

Examples of R ¹ which is a straight or branched alkyl or alkenyl group having 6 to 24 carbon atoms include a hexyl group, a heptyl group, an octyl group, a nonyl group, a decyl group, a undecyl group, a dodecyl group, a tridecyl group, a tetradecyl group, a pentadecyl group, a hexadecyl group, a heptadecyl group, an octadecyl group, a nonadecyl group, an icosyl group, a henicosyl group, a docosyl group, a tricosyl group, a tetracosyl group, a myristoleyl group, a palmitoleyl group, an oleyl group, a linoyl group, a linoleyl group, a ricinoleyl group, and an isostearyl group.
Examples of ^R2 which is a linear or branched alkylene or alkylenyl group having 1 to 6 carbon atoms include a methylene group, an ethylene group, a propylene group, a trimethylene group, a tetramethylene group, a pentamethylene group, a hexamethylene group, etc. As described above, ^R3 and ^R4 are the same or different and are a hydrogen atom or a linear or branched alkyl group having 1 to 6 carbon atoms (typically a methyl group).

Alkyl dimethyl ammonium salts and alkyl benzyl dimethyl ammonium salts are also included as tertiary amine cationic surfactants. The alkyl groups constituting these tertiary ammonium salts are linear or branched alkyl groups having about 16 to 35 carbon atoms, typically linear alkyl groups such as hexadecyl, heptadecyl, octadecyl, nonadecyl, icosyl, henicosyl, docosyl, tricosyl, tetracosyl, pentacosyl, hexacosyl, heptacosyl, octacosyl, nonacosyl, triacontyl, hentriacontyl, dotriacontyl, tritriacontyl, tetratriacontyl, and pentatriacontyl. Among these, hexadecyl (16 carbon atoms), octadecyl (18 carbon atoms), and docosyl (22 carbon atoms) are preferred linear alkyl groups. The anion constituting the ammonium salt may be a halogen ion such as chlorine, iodine, or bromine, or an organic anion such as methosulfate, ethosulfate, methophosphate, or ethophosphate, typically a chlorine ion.

Examples of the tertiary amine cationic surfactant represented by general formula (I) include dimethylaminoethyl amide stearic acid, dimethylaminopropyl amide stearic acid (i.e., stearamidopropyl dimethylamine), diethylaminoethyl amide stearic acid, diethylaminopropyl amide stearic acid, dipropylaminoethyl amide stearic acid, dipropylaminopropyl amide stearic acid, dimethylaminoethyl amide palmitic acid, dimethylaminopropyl amide palmitic acid, dimethylaminoethyl amide myristate, dimethylaminopropyl amide myristate, dimethylaminoethyl amide behenic acid, dimethylaminopropyl amide behenic acid, and the like, and among these, dimethylaminopropyl amide stearic acid, diethylaminoethyl amide stearic acid, and dimethylaminopropyl amide behenic acid are preferred.

As the tertiary amine cationic surfactant represented by the general formula (I), commercially available products can be used. For example, Catinal MPAS (trade name, manufactured by Toho Chemical Industry Co., Ltd.) can be used as the dimethylaminopropylamide stearate, Ayacol AMINEAMIDE 50E (trade name, manufactured by Seiwa Kasei Co., Ltd.) can be used as the diethylaminoethylamide stearate, and Catinal BMPA(K) (trade name, manufactured by Toho Chemical Industry Co., Ltd.) can be used as the dimethylaminopropylamide behenate.

Examples of quaternary ammonium salt cationic surfactants include alkyltrimethylammonium salts. The alkyl groups that can form the quaternary ammonium salt cationic surfactant and the anions that form the salt are the same as those exemplified for the tertiary ammonium salts described above.

Examples of alkyltrimethylammonium salts include lauryltrimethylammonium chloride, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride (i.e., steartrimonium chloride), behenyltrimethylammonium methylsulfate, behenyltrimethylammonium chloride, cetyltrimethylammonium bromide, stearyltrimethylammonium bromide, etc., of which stearyltrimethylammonium chloride and behenyltrimethylammonium chloride are preferred. Commercially available products such as Catinal STC-80 (C) (product name, manufactured by Toho Chemical Industry Co., Ltd.) can be used as stearyltrimethylammonium chloride, and Catinal DC-80 (C) (product name, manufactured by Toho Chemical Industry Co., Ltd.) can be used as behenyltrimethylammonium chloride.

　One or more of the tertiary amine cationic surfactants and quaternary ammonium salt cationic surfactants can be selected and used, and it is also possible to use both a tertiary amine cationic surfactant and a quaternary ammonium salt cationic surfactant.

The amount of these cationic surfactants to be blended can be freely selected depending on the formulation and aspect of the hair cosmetic of the present invention, but the blending ratio relative to the total amount of hair cosmetic 1 is preferably 0.1 to 10 mass%, and more preferably 0.2 to 5 mass%. If the blending amount is less than 0.1 mass%, it is difficult to fully achieve the effects of excellent usability and improved combability when used as a hair cosmetic, while blending more than 10 mass% does not provide an improvement in effect commensurate with the increase in blending amount.

[Component (3): Higher alcohol]
In the case of hair cosmetics, it is preferable to incorporate a higher alcohol, particularly in the case of hair treatment agents such as hair rinses and hair conditioners. Higher alcohol is an essential ingredient (ingredient (3)) of hair cosmetic 1, and a gel with a layered structure (lamellar structure) is formed by contacting higher alcohol with the tertiary amine cationic surfactant and/or quaternary ammonium salt cationic surfactant and water. Therefore, when oils such as the glyceryl (diisostearate/hydrogenated rosin acid) are added to this system and emulsified, a preparation suitable for a milky or creamy hair rinse or hair conditioner in which fine oil droplets are dispersed in the gel is obtained.

As the higher alcohol of component (3), a monohydric aliphatic alcohol is used, and there is no particular limitation so long as it is a higher alcohol that can be used in cosmetics, and examples include lauryl alcohol, myristyl alcohol, cetyl alcohol (cetanol), cetostearyl alcohol, stearyl alcohol, arachyl alcohol, behenyl alcohol, oleyl alcohol, jojoba alcohol, chimyl alcohol, batyl alcohol, isostearyl alcohol, octyldodecanol, (C14-22) alcohol, and (C20-22) alcohol, and the like, and one or more of these higher alcohols can be blended.

The amount of higher alcohol (3) in hair cosmetic 1 is preferably 0.2-20% by mass, and more preferably 1-10% by mass, relative to the total amount of hair cosmetic 1. If the amount is less than 0.2% by mass, it becomes difficult to maintain a stable emulsion system as described above, and even if the amount exceeds 20% by mass, the stability of the emulsion system does not improve commensurate with the increase in the amount.

[Component (4): Water]
In addition to the above-mentioned components (1) to (3), hair cosmetic preparation 1 contains water as an essential component (4). As the (4) water, ion-exchanged water, purified water, tap water, natural water, etc. can be used, and it can be freely blended depending on the formulation and form of hair cosmetic preparation 1 of the present invention. Specifically, it is typical to blend water as the remainder of the blend amounts of the above-mentioned essential components (1), (2), and (3) and the blend amounts of other components blended taking into consideration the formulation and form of hair cosmetic preparation 1.

Hair cosmetic preparation 1 is characterized by the fact that it provides an excellent feel when used without the inclusion of silicones. Silicones commonly used in hair cosmetics include low-polymerized dimethicone, high-polymerized dimethicone, and aminopropyl dimethicone, but Hair cosmetic preparation 1 provides a feel when used that is equal to or better than hair cosmetics that contain these silicones, even without the inclusion of these silicones.

In addition to the essential ingredients (1) to (4) described above, the hair cosmetic composition 1 of the present invention can contain a wide range of other ingredients that are typically used in cosmetics, depending on the intended use, as long as the cosmetic composition's effectiveness, stability, etc. are not impaired.

Other ingredients that can be added in addition to the above-mentioned components (1) to (4) include, for example, oils other than components (1) and (3), surfactants other than component (2), polymeric compounds, moisturizers, whitening agents, texture improvers, drugs, UV absorbers, proteins, protein hydrolysates or derivatives thereof, amino acids or derivatives thereof, antioxidants, sequestering agents, pH adjusters, preservatives, pigments, colorants, fragrances, etc., which can be added as appropriate.

If the blending amount is less than 0.1 mass%, it is difficult to fully achieve effects such as a feeling of use equal to or greater than those of oil-based hair cosmetics containing silicones, while blending more than 30 mass% does not provide an improvement in effect commensurate with the increase in blending amount.

[Component (22): Oil other than fatty acid triglyceride]
The oil other than fatty acid triglyceride (component (12)) (hereinafter referred to as "oil 2") blended in hair cosmetic preparation 2, which is the second aspect of the present invention, is an oil blended to dissolve fatty acid triglyceride and other components, thereby improving the stability of the formulation and imparting smoothness and manageability to the hair.
The oil 2 is not particularly limited as long as it is an oil other than fatty acid triglycerides and is used in cosmetics, and any oil can be used, regardless of whether it is volatile or non-volatile, or whether it is an animal oil, vegetable oil, synthetic oil, or the like.
Specific examples of the oil agent 2 include (C13-15) alkanes, (C15-19) alkanes, (C18-21) alkanes, (C21-28) alkanes, mineral oils, liquid paraffin, heavy liquid isoparaffin, light liquid isoparaffin, α-olefin oligomers, squalane, polyisobutylene, polyisobutene, polybutene, hydrogenated polyisobutene, isohexadecane, isododecane, microcrystalline wax, ceresin, and petrolatum. Hydrogenated oils; waxes such as carnauba wax, candelilla wax, beeswax, rice bran wax, and shellac wax; oils and fats such as olive oil, castor oil, camellia oil, rice bran oil, macadamia nut oil, Theobroma grandiflorum seed oil, coconut oil, shea butter, and Astrocaryum murumuru seed oil; jojoba oil, diisobutyl adipate, isopropyl isostearate, cetyl 2-ethylhexanoate, neopentyl glycol dicaprate, isopropyl palmitate, palmitate, ester oils such as 2-ethylhexyl tartrate, isononyl isononanoate, isopropyl myristate, 2-octyldodecyl myristate, and diisostearyl malate; amino acid oils such as N-lauroyl-L-glutamic acid-2-octyldodecyl ester and N-lauroyl-L-glutamic acid di(phytostearyl.2-octyldodecyl); higher fatty acids such as isostearic acid, oleic acid, lauric acid, myristic acid, palmitic acid, and stearic acid; higher alcohols such as octanol, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetearyl alcohol, arachidyl alcohol, behenyl alcohol, coconut alcohol, (C14-22) alcohol, (C20-22) alcohol, hexyldecanol, octyldodecanol, batyl alcohol, oleyl alcohol, and isostearyl alcohol; and lanolin or lanolin derivatives. Among these, preferred are hydrocarbon oils, waxes, ester oils, etc. These oils may be blended either individually or in combination.

The amount of oil 2 in hair cosmetic 2 can be freely selected depending on the formulation and aspect of the hair cosmetic of the present invention, but the blending ratio relative to the total amount of hair cosmetic 2 is preferably 10 to 90% by mass, more preferably 15 to 70% by mass, and even more preferably 20 to 50% by mass. If the blending amount is less than 10% by mass, it is difficult to fully achieve the effects of dissolving other ingredients, improving the stability of the formulation, and imparting smoothness and manageability to hair, while blending in more than 90% by mass does not provide an improvement in effect commensurate with the increase in blending amount.

Hair Cosmetic Preparation 2 is characterized by its excellent feel when used, even without the inclusion of silicones that provide an excellent feel to the touch. Silicones commonly used in oil-based hair cosmetics include low-polymerized dimethicone, high-polymerized dimethicone, and aminopropyl dimethicone, but Hair Cosmetic Preparation 2 does not contain these silicones and yet has the same excellent feel and feel when used as oil-based hair cosmetics that contain silicones.

In addition to the above-mentioned components (12) and (22), hair cosmetic 2 may contain a wide variety of other ingredients commonly used in cosmetics depending on the intended use, so long as the cosmetic's effectiveness, stability, etc. are not impaired.

Other ingredients that can be added in addition to component (12) and component (22) include, for example, surfactants, polymeric compounds, moisturizers, UV absorbers, proteins, protein hydrolysates or derivatives thereof, amino acids or derivatives thereof, antioxidants, sequestering agents, pH adjusters, preservatives, pigments, colorants, fragrances, etc.

The hair cosmetic 2 can be in the form of a liquid, emulsion, paste, cream, gel, etc., with liquid, paste, and cream being preferred.

Hair cosmetic product 2 can be widely used in a variety of cosmetics, and is particularly suitable for use as oily hair cosmetics such as hair oil and hair wax.

Next, the first and second aspects of the present invention will be specifically explained using examples, but the present invention is not limited to these examples. Note that the numerical values shown in the tables of the examples are all in mass % relative to the total mass of the cosmetic.

Example 1 and Comparative Examples 1 to 4: Hair conditioner (using tertiary amine cationic surfactant)
(A) and (C) shown in Table 1 were mixed and heated to 75°C. Then, in a 300 mL beaker, (B) was added little by little to (A) while stirring at 200 rpm using an anchor blade. (C) was further added to emulsify, and the mixture was cooled to 60 to 65°C to gel. Then, the mixture was stirred at 3000 rpm for 10 minutes using a homomixer, cooled on ice, and then (D) and evaporated water (water in an amount equivalent to the water evaporated during the above process) were added to prepare a hair conditioner.
Damaged hair was prepared by the following method and evaluated according to the hair feel evaluation method described below.

[Creation of damaged hair]
In order to make the degree of damage of the hair constant, damaged hair that was bleached was prepared for use in evaluating the hair texture. The specific preparation procedure is as follows.
A bundle of healthy black hair was immersed in 2% sodium polyoxyethylene (3) lauryl ether sulfate heated to 40°C and kept at 40°C for 30 minutes. After that, the bundle was washed with running tap water at 40°C for 1 minute and dried with a hair dryer.
Next, as a bleaching treatment, the hair bundle was immersed in a 1:1 (mass ratio) mixture of 6% hydrogen peroxide and 2% ammonia water at 30° C. for 30 minutes, and then washed with running tap water at 40° C. After towel drying, the hair bundle was immersed in a mixture of 0.1 M citric acid and 0.2 M disodium hydrogen phosphate as an acid rinse at room temperature for 5 minutes, and then washed with running tap water at 40° C. Furthermore, the hair bundle was immersed in ion-exchanged water at room temperature for 10 minutes, and then towel-dried and dried with a hair dryer. This bleaching treatment operation was repeated three times.

[Hair feel evaluation method]
The prepared damaged hair bundle (length 15 cm, weight 2 g) was immersed in 1% polyoxyethylene (3) sodium lauryl ether sulfate heated to 40° C., and after shaking for 10 minutes with a heat-retaining shaker while keeping the temperature at 40° C., the hair bundle was washed for 1 minute under running tap water at 40° C. After towel drying, half the weight of the hair bundle was applied to the hair bundle and left to stand at 40° C. for 10 minutes, and the hair bundle was washed for 1 minute under running tap water at 40° C. Thereafter, the hair bundle that had been towel-dried and dried with a hair dryer was evaluated by 10 panelists for moist feeling, smoothness, and slippery feeling.
The evaluation was based on the following evaluation criteria, with the hair cosmetic of Comparative Example 1 being given a score of 0 and the other hair cosmetics being given a score of 5 on the following scale. The total scores of the 10 panelists are shown in Table 1.

[Hair evaluation criteria]
2 points: Very good 1 point: Good 0 points: Same -1 point: Slightly bad -2 points: Bad

The results in Table 1 clearly show that the hair strands treated with the hair conditioner of Example 1, which contains component (1) (diisostearate/hydrogenated rosin acid) glyceryl, component (2) dimethylaminopropylamide stearate (stearamidopropyl dimethylamine) as a tertiary amine cationic surfactant, component (3) cetanol and behenyl alcohol as higher alcohols, and component (4) purified water as water, have excellent moisturizing, smoothness, and silky feel equal to or greater than the hair strands treated with the hair conditioners of Comparative Examples 2 to 4, which contain low- or high-polymerized silicone or aminopropyl dimethicone instead of component (1), and the hair conditioner of Comparative Example 1, which does not contain component (1) or silicones, and thus provide an excellent feel when used.

Example 2 and Comparative Examples 5 and 6: Hair conditioner (using a quaternary ammonium salt type cationic surfactant)
Hair conditioners were prepared using the components shown in Table 2 in the same manner as in Example 1 and Comparative Examples 1 to 4. Damaged hair was also prepared and evaluated in the same manner as in Example 1 and Comparative Examples 1 to 4 according to the above-mentioned hair feel evaluation method. The hair cosmetic of Comparative Example 5 was given a score of 0, and the other hair cosmetic compositions were rated on the same 5-point scale as above, and the total scores of the evaluations by the 10 panelists are shown in Table 2.

The results in Table 2 clearly show that the hair strands treated with the hair conditioner of Example 2, which contains component (1) glyceryl (diisostearate/hydrogenated rosin acid), component (2) stearyltrimethylammonium chloride (steartrimonium chloride) as a quaternary ammonium salt cationic surfactant, and component (3) cetanol and behenyl alcohol as higher alcohols, have a superior feel in terms of moisturization, smoothness, and silkiness to the touch and a superior feel when used compared to the hair strands treated with the hair conditioner of Comparative Example 5, which contains highly polymerized silicone and aminopropyl dimethicone instead of component (1), and Comparative Example 6, which does not contain component (1) or silicones.

The results in Tables 1 and 2 clearly show that when component (1) (glyceryl diisostearate/hydrogenated rosin acid) is added, it provides an excellent feel when used that is not inferior to when silicones are added instead.

[Combability Evaluation]
The damaged hair bundle (length 30 cm, weight 10 g) prepared in the above [Preparation of damaged hair] was immersed in 1% sodium polyoxyethylene (3) lauryl ether sulfate heated to 40°C, and after shaking for 10 minutes with a heat-retaining shaker while keeping the temperature at 40°C, the hair bundle was washed for 1 minute in running tap water at 40°C and towel-dried. A conditioner in Table 2 was applied in an amount equivalent to half the weight of the hair bundle and left to stand for 10 minutes at 40°C, after which the hair bundle was washed for 1 minute in running tap water at 40°C and towel-dried.

The moisture content was adjusted to 50±2% of the weight of the hair bundle, and a dynamic friction coefficient measuring device equipped with a comb unit (product name: Trinity Lab Handy Lab Tester Type: TL701) was passed over the hair bundle from the root to the tip at a speed of approximately 6 cm/sec, and the average load value over a 10 cm portion near the middle of the hair bundle was calculated to evaluate the combability when wet.
Next, instead of a hair bundle whose moisture content had been adjusted to 50±2% of the hair bundle weight, the hair bundle after drying with a hair dryer was similarly measured and evaluated as combability when dry.
The results are shown as the relative weighted average value when the weighted average value of the hair bundle not treated with conditioner (hereinafter referred to as "control") is set to 1. The smaller the relative weighted average value, the better the combability. The results of combability when wet are shown in Figure 1, and the results of combability when dry are shown in Figure 2.

1 and 2, it was confirmed that the combability in wet and dry conditions was improved in the hair bundles treated with the conditioner of Comparative Example 5 or Example 2 compared to the control. In Comparative Example 6, the combability in wet conditions was improved, but the combability in dry conditions was not improved. Therefore, it is considered that the improvement in the combability in dry conditions is largely due to the effect of glyceryl (diisostearate/hydrogenated rosin acid) or silicones (oils).
In addition, it was revealed that the degree of effect in terms of combability was almost the same in Comparative Example 5 and Example 2, and it was revealed that glyceryl (diisostearate/hydrogenated rosin acid) has sufficient functionality as a substitute for silicones.

Example 3 and Comparative Example 7: Hair oil Hair oil was prepared by mixing the components shown in Table 3 at room temperature. Furthermore, damaged hair was prepared in the same manner as in Examples 1 and 2 and Comparative Examples 1 to 6, and evaluated according to the hair feel evaluation method described below.

[Hair feel evaluation method]
The prepared damaged hair bundle (length 30 cm, weight 9 g) was wetted with water, towel-dried, and then 0.1 g of hair oil was applied, combed three times, and dried with a hair dryer. The feel of the hair oil when applied and the condition of the hair (moisturizing feeling), the condition of the finished hair after drying with a hair dryer (suppleness, lightness), and the condition of the hair 2 to 3 hours after application of the hair oil (tieness of the hair bundle, gloss) were sensorily evaluated by five panelists according to the following hair evaluation criteria, and the results are shown in Table 3 as the average scores of the five panelists.

[Hair evaluation criteria]
The result of Comparative Example 7 was set as the standard (0 points), and the results of the other Examples and Comparative Examples were evaluated in increments of 0.5 points between -2 points and 2 points (the higher the point, the better the result).

The results in Table 3 clearly show that applying the hair oil of Example 3, which contains component (12) fatty acid triglyceride (glyceryl diisostearate/hydrogenated rosin acid), instead of the hair oil of Comparative Example 7, which contains silicones, provides a superior effect in terms of moisturizing the hair upon application, the suppleness and lightness of the finished hair, and the manageability and shine of the hair strands 2 to 3 hours after application.

Example 4 and Comparative Example 8: Hair wax (A) and (B) shown in Table 4 were mixed and heated to 85°C. (C) was mixed at room temperature and stirred until homogenous. Then, (B) was added to (A) and stirred, and (C) was further added and stirred. Furthermore, (D), (E) and evaporated water (water in an amount equivalent to the water evaporated during the stirring in the above step) were added to prepare a hair wax. Then, evaluation was performed according to the following hair feel evaluation method.

[Hair feel evaluation method]
The hair of the cutting mannequin was blocked and an appropriate amount of hair wax was applied.
Five panelists performed a sensory evaluation of the feel of the hair wax when applied (spreading on the hair), the condition of the hair when styling (smoothness of the hair, stiffness, hair bundle feel (hair being gathered into blocks)), and the condition of the hair 2 to 3 hours after application (style retention, shine) according to the following evaluation criteria, and the results are shown in Table 4. The results are shown as the average scores of the five panelists.

[Hair evaluation criteria]
The result of Comparative Example 8 was set as the standard (0 points), and the results of the other Examples and Comparative Examples were evaluated in increments of 0.5 points between -2 points and 2 points (the higher the point, the better the result).

The results in Table 4 show that the hair wax of Example 4, which contains component (12) fatty acid triglyceride (glyceryl diisostearate/hydrogenated rosin acid), exhibits better effects than the hair wax of Comparative Example 8, which contains silicones, and in particular provides excellent smoothness and hair bundle feel.

The results in Tables 3 and 4 show that when fatty acid triglycerides are mixed with other oils in hair oils and hair waxes, even without silicones, they provide excellent effects that are no less effective than those that do contain silicones.

Examples 5 and 6 and Comparative Examples 9 to 12: Hair Masks Hair masks of each example were prepared using the components shown in Tables 5 and 6 according to the preparation method described below.
After preparation, damaged hair was prepared in the same manner as in Example 1 and Comparative Examples 1 to 4, and treated in the same manner as in Example 1 and Comparative Examples 1 to 4 to evaluate the hair feel, except that the prepared hair mask was used instead of a conditioner, and the moist feeling, smoothness, and manageability of the hair bundle were evaluated.

For Example 5, Comparative Examples 9, and 10, the hair cosmetic product of Comparative Example 9 was given a score of 0, and the hair cosmetic products of Example 5 and Comparative Example 10 were evaluated on the same 5-point scale as above, and the total scores of the evaluations by the 10 panelists are shown in Table 5. For Example 6, Comparative Examples 11, and 12, the hair cosmetic product of Comparative Example 11 was given a score of 0, and the hair cosmetic products of Example 6 and Comparative Example 12 were evaluated on the same 5-point scale as above, and the total scores of the evaluations by the 10 panelists are shown in Table 6.
