Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a hair that imparts luster, smoothness and moisturization to the hair to make the hair supple and to maintain the gloss and smoothness of the hair for a long period of time. Regarding the conditioner.

[Conventional technology]

Conventionally, as a hair conditioner, generally, a cationic surfactant having a softening effect on hair is mainly used, and an oil component, a moisturizing agent, etc. are emulsified with the cationic surfactant and the nonionic surfactant. Was used (for example, "Latest Cosmetic Chemistry", edited by Japan Cosmetic Engineers Association, published by Yakuji Nippo Co., Ltd., p191-193, "Fragrance Journal" No.32 (1978), p61-62, etc.) .

[Problems to be Solved by the Invention]

However, although this hair conditioner has an excellent action to make the hair supple, the cationic surfactant adsorbs to the hair to form a strong coating film on the hair, so that the oil component is the cationic surfactant. Since it cannot be penetrated into the hair due to the film of No. 3, and the oily component is only adhered to the hair, it is washed off by washing the hair, and accordingly, the gloss and smoothness of the hair are lost. there were.

Therefore, an object of the present invention is to provide a hair conditioner which imparts luster, smoothness and moisturization to the hair to make the hair supple and to maintain the luster and smoothness of the hair for a long period of time.

[Means for Solving the Problems]

The present invention provides a hair conditioner, behenic acid of 0.
5 to 3.0% by weight, triethanolamine 0.1 to 1.0% by weight, poly (dimethylmethylene piperidinium chloride) 0.2 to
2.0% by weight, 3.0 to 40.0% by weight of an oily component containing a silicone oil and a mineral oily material, and 1.0% a surfactant containing a nonionic surfactant and an anionic surfactant.
The above object has been achieved by composing the composition in an amount of up to 10.0% by weight and emulsified in water.

When it is lost, it will bleed onto the surface of the hair.
Long-term gloss and smoothness is not lost by washing hair
It lasts for a while.

Each component and its action in the hair conditioner of the present invention will be described in detail as follows.

First, the hair conditioner of the present invention is particularly different from the conventional hair conditioner, in the hair conditioner of the present invention, soap (soap) is formed with behenic acid and triethanolamine, and the oily component is watered with this soap. That is, the emulsion particles have very low viscosity and are fine, and they are emulsified in a stable state.

And, in forming the soap emulsified system, behenic acid is particularly used as a higher fatty acid because behenic acid has a large molecular weight, and as mentioned above, it makes the emulsified particles fine, and the oil component is relatively large. This is because it is suitable for emulsification in a stable state and has a property of imparting a firm feeling to the hair, that is, moisturizing.

Further, in forming the above-mentioned soap emulsification system, using triethanolamine as an alkaline agent is suitable for forming a stable emulsion state of triethanolamine having a low viscosity, and it is also suitable for hair itself. This is because it has the property of imparting luster.

In the present invention, the behenic acid content is 0.5
~ 3.0% (% by weight, all percentages below are% by weight, and the blending amount is the amount that it occupies in the hair conditioner), but this is the blending of behenic acid. If the amount is less than 0.5%, the effect of forming a soap emulsification system to emulsify the oil component with fine particles cannot be sufficiently exerted, and if the content of behenic acid is more than 3.0%, the viscosity is This is because it becomes higher and the emulsified particles also become larger. A particularly preferable amount of behenic acid is 1.0 to 2.8.

The amount of triethanolamine added is 0.1 to 1.0.
%, But this is because the amount of triethanolamine is 0.
If it is less than 1%, the effect of emulsifying the oily component with fine particles cannot be sufficiently exerted by forming soap, and if the blending amount of triethanolamine is more than 1.0%, the alkalinity becomes strong, This is because the hair will be damaged. The particularly preferable blending amount of this triethanolamine is 0.3 to 0.6%.

In the present invention, poly (dimethylmethylene piperidinium chloride) is blended in an amount of 0.2 to 2.0%, and this poly (dimethyl methylene piperidinium chloride) is a kind of cationic polymer, and is adsorbed to the hair to moisturize the hair and hair. Supple. In the present invention, the use of polydimethylmethylenemethylenepiperidinium chloride as the cationic polymer is particularly advantageous because polydimethylmethylenemethylenepiperidinium chloride has a long-lasting action to supple the hair,
This is because the suppleness of the hair is maintained for a long time. However, this poly (dimethylmethylene piperidinium chloride)
It is less cationic than conventionally used cationic surfactants and does not form a strong film on the hair like cationic surfactants to prevent the penetration of oily ingredients into the hair.

In the present invention, this polydimethylmethylene piperidinium chloride is blended in an amount of 0.2 to 2.0%. However, when the blending amount of polydimethylmethylene piperidinium chloride is less than 0.2%, the effect of moisturizing the hair and hair If the amount of polydimethylmethylene piperidinium chloride is more than 2.0%, the emulsified state will be impaired, the commercial value will decrease, and the hair will become sticky. Is. A particularly preferred amount of this polydimethylmethylene piperidinium chloride is 0.5
~ 1.5%.

Further, when the above-mentioned behenic acid and triethanolamine react to form soap, the polydimethyldimethylmethylenepiperidinium chloride has a more remarkable effect of forming a complex with the soap to make the hair supple. Will be demonstrated.

This polydimethyl dimethyl methylene piperidinium chloride having a concentration of 40% is commercially available from Asahi Denka Kogyo Co., Ltd. under the trade name of ADEKA CHATIOACE PD-50 and can be easily obtained.

The oily component contains silicone oil and a mineral oily material as essential components. Silicone oil imparts luster and smoothness to the hair, improves combability of the hair, and prevents moisture from adhering to the hair from the outside such as in the atmosphere.

As the above-mentioned silicone oil, for example, methylpolysiloxane, methylpolycyclosiloxane, methylphenylsiloxane, etc. can be used.

On the other hand, examples of the mineral oily material include liquid paraffin, paraffin wax, petrolatum, and α-olefin oligomer.These mineral oily materials also impart gloss and smoothness to the hair and pass through the hair. It has the effect of making the hair good and keeping the hair moist.

In the present invention, the oily component is, in addition to the silicone oil and the mineral oily material, for example, castor oil, jojoba oil, avocado oil, almond oil and other vegetable oils, myristic acid ester, adipic acid ester, isooctanoic acid ester, olein. It may contain higher fatty acid ester such as acid ester, higher alcohol such as cetyl alcohol, stearyl alcohol, oleyl alcohol, 2-octyl dodecanol and the like.

In the present invention, the above oily component is blended in an amount of 3.0 to 40.0. This has the effect of imparting gloss and smoothness to the hair and improving combability of the hair when the blending amount of the oily component is less than 3.0%. And the effect of keeping the hair moisturized is not fully exerted, and when the amount of the oily component is more than 40.0%,
This is because a uniform emulsified state cannot be obtained and the hair becomes sticky. A particularly preferable amount of this oily component is in the range of 5 to 20%.

In the above oily component, silicone oil is 1
The range of ~ 10% is preferable, and the mineral oily material is 2 ~.
30% is preferable.

The surfactant contains a nonionic surfactant and an anionic surfactant, and the nonionic surfactant acts to emulsify an oil component in water. However, only by emulsifying with this nonionic surfactant, the low-viscosity and emulsified state with fine particles as aimed at by the present invention cannot be obtained.

On the other hand, the anionic surfactant acts as a penetrant that facilitates penetration of the oily component into the hair.

Examples of nonionic surfactants include polyoxyethylene (20) cetyl ether (the numerical values in parentheses indicate the number of moles of ethylene oxide added; the same applies below) and polyoxyethylene (10) oleyl ether. , Polyoxyethylene (9) lauryl ether, lipophilic glycerin monostearate, polyoxyethylene (2)
Monostearate and the like can be mentioned, and it is suitable to use those having a large HLB (hydrophilic and lipophilic balance) and those having a small HLB in combination to adjust the HLB to a lipophilic side of about 7 to 9. . Further, as the anionic surfactant, for example, lauryl sulfate, lauryl ether sulfate, lauryl phosphate, sucrose fatty acid ester, etc. are used. The weight ratio of the nonionic surfactant and the anionic surfactant is 1: 1 to 15: 1.
It is preferable to use the ratio of

In the present invention, this surfactant is blended in an amount of 1.0 to 10.0%. When the blending amount of the surfactant is less than 1.0%, the effect of emulsifying the oily component in water and the penetration of the oily component into the hair are achieved. This is because the effect of exerting the effect is not sufficiently exhibited, and when the content of the surfactant is more than 10.0%, the emulsified state is impaired and bubbles are generated. this,
A particularly preferable blending amount of the surfactant is 2.0 to 6.0%.

In the hair conditioner of the present invention, in addition to the above-mentioned behenic acid, triethanolamine, polydimethyldimethylmethylene piperidinium chloride, an oil component, an essential component of a surfactant, a chelating agent such as an edetate salt, a preservative, a fragrance, A rust preventive, a coloring agent, an ultraviolet absorber, vitamins, a polypeptide or its derivative, and the like, which are mixed in preparing a hair conditioner, can be added.

The method for preparing the hair conditioner of the present invention is not particularly limited, but when it is prepared by the method described below, a hair conditioner exhibiting its characteristics better can be obtained.

That is, hydrophobic oily ingredients, behenic acid, nonionic surfactants, etc. are heated and mixed in a molten state, and hydrophilic triethanolamine, anionic surfactants, etc. are dissolved by heating in water. Then, when these hydrophilic component and the hydrophobic component are mixed, behenic acid and triethanolamine react with each other at the same time when the respective components are mixed to form soap. The fact that the mixing of the respective components by the contact of the hydrophobic component and the hydrophilic component and the formation of the above-mentioned soap are carried out at the same time makes the emulsified particles fine, and has a good result in obtaining a low-viscosity and stable emulsified state. It is thought to bring about. Then, after the emulsified particles are finely divided in this manner, an aqueous solution of polydimethylmethylene piperidinium chloride is added to prepare a hair conditioner.

The hair conditioner prepared as described above is used by applying it to wet hair after washing with shampoo so that the hair can be washed off. For example, perm hair, colored hair, straight hair, hard hair,
Can be used on various types of hair.

Apply 1 to 2 of hair conditioner separately, 3g each, and
After being left for a minute, washed with water, dried and then weighed. Then, this hair is washed with the above shampoo, washed with water, dried and then weighed. Washing the hair with this shampoo, washing with water, drying and weighing are repeated twice more.

Test Results: The amount of hair conditioner on the hair measured by the above test is shown in Table 1 as% of the amount of hair conditioner first applied to the hair. In addition, "only water washing" in the table
Indicates that the hair conditioner was applied to the hair, and then washed with water and dried, and the number of times of hair washing indicates the number of times of washing with shampoo.

As shown in Table 1, the hair conditioners of Examples 1 and 2 of the present invention have a large residual amount on hair as compared with the hair conditioners of Comparative Examples 1 and 2, and particularly Comparative Examples 1 to 1
In the hair conditioner of No. 2, most of the hair was washed off by the first washing of hair, and the residual amount was completely lost after the second washing of hair, whereas in the hair conditioners of Examples 1 and 2 of the present invention, the third amount of washing was performed. It remained on the hair after washing and showed that the luster and smoothness of the hair can be maintained for a long period of time.

(2) Combing force test of hair Test method: 5 g of hair washed with shampoo, washed with water, and dried, and then applied with 10 g each of the hair conditioners of Examples 1-2 and Comparative Examples 1-2, and left for 3 minutes. Then, after washing with water and drying, the combing force is measured using a combing force tester (a machine for measuring the frictional force when the hair and the comb rub). Then, the hair is washed with shampoo, washed with water, dried, and then the combing force is measured. This hair washing, water washing, drying and combing force measurement are repeated twice more.

Test results: Table 2 shows the results of measuring the combing force. When measuring the comb-passing force, the same operation as described above was repeated even when no hair conditioner was used, and the results are shown in Table 2 as blanks.
