Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stable polyol containing a natural scrub raw material,

This specification relates to a cosmetic composition comprising an oily portion comprising a polar oil and a non-polar oil, a polyol portion, and a scrub raw material, and to the improvement of the stability of such a cosmetic composition.

Skin stimuli are diverse, for example, environmental stimuli such as strong winds of the air, hot winds, cold spots, air pollutants, acid rain, ultraviolet rays, etc., which are seasonal characteristics of the atmosphere, . A representative mechanism that effectively defends against these stimuli is defense against keratin.

The formation of keratin in the skin is generally proliferated from the lowest epidermal layer, slowly rising up to the epidermis, and then separated from the epidermal layer naturally after a certain period of time. This is called keratinization. However, in the modern society, due to excessive hormone abnormality due to stress and a sudden change in the external environment, the skin of the stratum corneum does not fall off due to atmospheric pollutants or ultraviolet rays, The skin tone becomes unstable and the skin becomes rough and dull. In addition, when making a color hue, the makeup appears uneven due to the uneven horny layer, and so-called make-up seeming to be said can be made.

A skin scrub formulation is a form of cosmetics made for exfoliation, which is applied to the skin to massage the nerves and blood vessels distributed in the dermis and subcutaneous tissues of the skin due to the scrub materials contained in the formulation. Stimulates blood circulation of the skin, and at the same time helps to easily remove the keratinized keratin of the skin, thereby preventing the stratum corneum from being thickened.

On the other hand, microplastics (aka microbeads), which is a scouring material used in the cosmetics industry, are recognized as a serious cause of environmental pollution, and the necessity of natural materials to replace them is increasing. In recent years, well-being trends and home peeling have gained popularity in the market for peeling products, and demand for effective, stable and convenient scrub products is increasing while using natural scrub raw materials. However, In the case of natural scrub materials having high solubility, it is very difficult to disperse them in a stable state in a stable state. Therefore, research for solving these problems and meeting the needs of consumers is urgent.

Sugar is a typical natural scrub raw material used in various cosmetic or cleaning products. However, unlike salt, 8 hydroxy groups per molecule are easily hydrogen bonded to water molecules, resulting in high hygroscopicity and high solubility in water It is very difficult to disperse the solid phase state as it is in a stable oil phase formulation because of its characteristics, and it is difficult to maintain the stability of the formulation.

Thus, unlike salt, the preparation of stable formulations containing sugar as a scrub feed was one of the longstanding challenges in the art.

In order to solve this problem, in one aspect, the present invention aims to improve the stability of the interface membrane by controlling the polarity by changing the ratio of the internal oil, and further secures long-term stability of the composition containing a high content of sugar. This is a solution to the problem that has not been solved in the industry for a long time.

[Example 1] Preparation of composition of O / P gel formulation

When 20% or more of the sugar is contained in the formulation based on the type of polyol which is a water-free formulation (Oil in Polyol, O / P gel), the hardness of the formulation drops sharply and phase separation in a few days And the stability is low due to phase separation when stored at room temperature for a long period of time. Therefore, a composition capable of securing long-term stability while containing more than 30% of highly soluble sugar in a formulation was studied.

Ingredients used in the preparation of the oil-in-poly gel composition according to one aspect of the present invention are shown in Table 1 below, and the composition was prepared according to the following procedure.

(1) The oils in the oil phase (oil phase part) were dispersed (or agitated or emulsified) evenly at an appropriate rate using an agi mixer (SSC811CA, Shinwon Industries) at room temperature after weighing (Explorer Pro, OHAUS).

(2) Sucrose stearate is added to glycerin, caprylic / capric triglyceride, purified water, sucrose laurate of polyol (polyol part) Heat up to 70 ℃ (Essential to keep below 80 ℃ - If the temperature is higher than this, the physical properties of surfactant sucrose laurate will change) and disperse evenly with homomixer (TK HOMOMIXER MARK II f model, TOKUSHU KIKA KOGYO CO. LTE) Or stirring or emulsifying).

(3) Homomixing emulsification (about 3,500 rpm, proceeding with increasing rpm as the O / P gel was increased), slowly adding the oily portion to the polyol portion to less than 5% of the total volume. At this time, it was visually confirmed whether the O / P gel was well formed.

(4) When the viscosity of the formed O / P gel becomes high and homomixing becomes impossible, the contents are transferred to a paddle mixer, and the remaining oily portion is stirred while stirring at a speed of 240-250 rpm. At this time, the O / P gel was similarly visually inspected to see whether it was well formed.

(5) After the O / P gel formation was completed, the preservative and flavor were added and further paddle-mixing was carried out (Direct Driven Stirrer, YOUNG HANA TECH.

(6) Paddle mixing was carried out so that the scrub material could be uniformly dispersed at the same rpm (240 to 250 rpm).

In the above table, the hydrocarbon-based oil is not limited to hydrogenated polyisobutene (Hydrogenated polyisobutylene), hydrotreated polyisobutylene (Hydrogenated polyisobutylene) in addition to Hydrogenated poly (C6-14 Olefin) (E.g., Hydrogenated polyisobutene, Hydrogenated polyisobutylene), Squalane, Squalane (Phytosqualane, Olive Squalane (e.g. EXOLIVE®), Sugarcane derived squalane (eg Neossance ™ (C6-14 olefin) and one or more of the above materials were also used as hydrogenated poly (C6) olefins -14 olefin) was used. In the case of using C10-C30 type of Guerbet alcohol (hexyldecanol, octyldodecanol, etc.) or an ester thereof in addition to Cetyl Ethylhexanoate, the same results were obtained in the following experimental examples.

It is also confirmed that natural products such as salt, coffee powder (for example, coffee grounds), walnut shell powder, and apricot seed powder can be used in place of the above-mentioned sugar. In the following examples, When the raw materials were used, it was confirmed that the results were very similar to those when the sugar alone was used.

[Experimental Example 1] Measurement of hardness before inputting scrub material

The hardness was measured (SUN RHEOMETER, SUN SCIENTIFIC CO. LTD) prior to the input of the scrub material when the formulation of Example 1 was prepared. The hardness was measured in a temperature environment of 30 ° C. The measurement speed of the hardness meter was 1 cm / 1 min, and 2 cm depth was measured for a total of 2 minutes. The maximum force required until the depth of 2 cm was determined as the final formulation hardness.

As a result, the hardness of the O / P gel before injecting the scrub material was as shown in Fig. 1 (LOT # CTRL is the control group, LOT # 1, LOT # 2, LOT # 3, LOT # 4, LOT # LOT # 7 represents Comparative Example 1, Comparative Example 2, Comparative Example 3, Comparative Example 4, Comparative Example 5, Comparative Example 6, and Comparative Example 7). (O / P gel hardness: comparative example 1> comparative example 2> comparative example 3).

In addition, as the content of sucrose fatty acid ester (for example, sucrose stearate) in the formulation was increased, the hardness of the O / P gel formulation was sharply decreased. At this time, it was estimated that the effect of hardness drop by sucrose fatty acid ester was larger than that of hydrocarbon oil (O / P gel hardness: Comparative Examples 1, 2 and 3> Comparative Example 4> Comparative Example 5). In addition, it has been confirmed that the sucrose fatty acid ester (for example, sucrose stearate) excludes overall stability of the formulation at a high temperature, and sucrose fatty acid ester is a great help to improve the high temperature stability of the above- (However, even when the sucrose fatty acid ester was excluded from the raw material, the stability or trend was maintained with the increase or decrease of the content of the hydrocarbon-based oil).

In addition, the formulation hardness increased as the ratio between the oil phase content in the formulation and the polyol content except for sucrose stearate was closer to 1: 4 (O / P gel hardness: Comparative Example 6> Comparative Example 1> , 7).

[Experimental Example 2] Confirmation of hardness change after input of scrub material

The hardness was measured as in Experimental Example 1, and the measurement was conducted after the preparation of the formulation by injecting the scrub raw material.

As a result, the change in hardness after the input of the scrub raw material (sugar and / or nutshell powder) was as shown in Fig. 2 (LOT # CTRL is a control group, LOT # 1, LOT # 2, LOT # 3, LOT # , LOT # 6 and LOT # 7 show Comparative Example 1, Comparative Example 2, Comparative Example 3, Comparative Example 4, Comparative Example 5, Comparative Example 6, and Comparative Example 7, respectively.

That is, after the introduction of the sugar scrub, the following day hardness of all the formulations was drastically decreased from 9 to 32 at the maximum. This is believed to be due to the self-solubility of the sugar scrub (sugar-glucose-OH group and hydrogen bond with the -OH group of the polyol), which causes the sugar to dissolve in the polyol and decrease its hardness.

The following characteristics were observed when observing the change of hardness for 2 weeks after the common decline of next day hardness.

 1) As the ratio of hydrocarbons in the oil phase in the O / P gel increased, the hardness of the next day remained almost unchanged. (The order of next day hardness is the order of Comparative Example 1> Comparative Example 2> Comparative Example 3, but the hardness at D + 14 days (14 days after the production of O / P gel) was reversed to Comparative Example 1 <Comparative Example 2 < Order.)

2) When the content of sucrose fatty acid ester was increased, the next day hardness remained unchanged. (Comparative Examples 4 and 5)

3) The hardness of Comparative Example 6 (the polyol portion except for Sucrose Stearate: O / P = 1: 4 optimum ratio) in which the formation of O / P gel hardness was highest showed a tendency to decrease even after the next day hardness. There was no correlation between the hardness of the initial O / P gel itself and the hardness change of the O / P gel containing sugar scrub.

4) The inclusion of sunflower oil in the upper part of the lake caused continuous hardness decline. As with ester-based oils, sunflower oil also affected the sustained hardness decline of O / P gel formulations containing sugar scrubs.

 On the other hand, in Comparative Examples 2 to 5, in which there was no or only a slight decrease in the hardness after the decrease in the common hardness of the next day, it was predicted that the compositions of these compositions were more stable than those of the other compositions.

[Experimental Example 3] Confirmation of stability of aging stability

It was observed for 30 days whether the stability of the formulation was improved by controlling the ratio of the polar ester-type oil which can cause destabilization of the O / P gel and the content ratio of the hydrocarbon-type oil having low polarity. For the stability observation, 45 ℃ incubation incubator was used. The temperature was 44.5 ± 1.0 ℃ and the shaking speed was 180 ~ 185 RPM.

3, LOT # 4, LOT # 5, LOT # 6 and LOT # 7 were compared with those of Comparative Example 1, Comparative Example 2, and Comparative Example 3 (LOT # 1, LOT # 2, , Comparative Example 4, Comparative Example 5, Comparative Example 6, and Comparative Example 7). FIG. 5 shows a comparison between the state where the stability of the formulation is deteriorated and the state where the stability of the formulation is maintained. (When the stability of the formulation is lowered, the scrub exhibits appearance on the surface and shows phase separation).

 The formulation stability increased sharply as the amount of hydrocarbon-based oil in the O / P gel was increased (days of formulation stability: Comparative Example 1 <Comparative Example 2 <Comparative Example 3) % To 30%, and when the amount is less than 15%, the stability of the formulation is drastically decreased. When it exceeds 30%, it is confirmed that when the product is commercialized, . When the oil level is used as a standard, the hydrocarbon-based oil is preferably in the range of about 30% to about 60% of the oil phase. If the oil level is less than 30%, the stability is drastically decreased. And the effect was significant.

Especially, as the content of sucrose fatty acid ester was increased, the stability of the formulation increased sharply. (Formulation Stability Retention Days: Comparative Examples 1 to 3 < Comparative Example 4 &gt; Comparative Example 5)

In addition, Comparative Example 6 had the highest O / P gel formation hardness, but showed the lowest stability at 45 degrees shaking (shaking) condition. There was no correlation between the O / P gel hardness and the temperature and physical stability of the O / P gel scrub formulations containing sugar scrub.

In Comparative Example 2, Comparative Example 7 in which the hydrocarbon oil was replaced with sunflower oil, which is a natural oil, was much more unstable than Comparative Example 2. In the O / P gel formulation containing sugar scrub, it was confirmed that not only the hydrocarbon oil content affected the formulation stability but also sunflower oil.

[Experimental Example 4] Stability test according to temperature change

The stability of the formulation was tested under temperature cycling conditions. Specifically, the experiment was repeated for more than one month in which the 12-hour period was maintained at -10 ° C for 12 hours, and the remaining 12-hour period was maintained at 40 ° C (the time required for the transition to raise or lower the temperature was 1 hour .

The result was as shown in FIG. 4 (LOT # 1, LOT # 2, LOT # 3, LOT # 4, LOT # 5, LOT # 6, Comparative Example 4, Comparative Example 5, Comparative Example 6, and Comparative Example 7). FIG. 5 shows a comparison between the state where the stability of the formulation is deteriorated and the state where the stability of the formulation is maintained. (When the stability of the formulation is lowered, the scrub exhibits appearance on the surface and shows phase separation).

That is, overall formulation stability was maintained for longer periods in the temperature cycle (Temp. Cycle) condition than in the 45 degree shaking (shaking) condition in all formulations. In addition, as in the case of the 45 ° shaking condition under the temperature cycle condition, it was observed that as the content of the hydrocarbon oil in the O / P gel oil part increased, the stability increased sharply as the content of sucrose fatty acid ester increased , Hardness at the time of O / P gel formation does not guarantee stability in O / P gel scrub formulations containing sugar scrub, and sunflower oil, which is one of the natural oils for moisturizing, is contained in the oil part It was confirmed that the stability of the formulation was adversely affected.

When the content of the hydrocarbon-based oil is in the range of 15% to 30%, the stability of the formulation is drastically decreased. When the content of the hydrocarbon-based oil is more than 30%, the oil- Or strong skin irritation. When the oil-based part is used as a standard, the hydrocarbon-based oil preferably ranges from about 30% to about 60% of the oil-based part. If the oil-based part is less than 30%, the stability is drastically decreased. And it was confirmed that the effect was significantly negative in terms of stimulation.

In the case of Formulation Example 1, the ratio of the hydrogenated poly (C6-14 Olefin) was set to 50 wt% of the oily phase (to prevent excessive hardness from dropping and to improve formulation stability), and O / P gel formulation Sucrose Stearate Was used in an amount of 0.55% by weight based on the total weight of the formulation. In order to maintain the hardness and stability of the proper scrub formulations, the ratio of polyol part to oil part except sucrose stearate was kept at about 1: 3.

In the case of Formulation Example 2, sunflower oil, which is a natural oil for use feeling and moisturizing feeling, was included, and sucrose stearate was added in an amount of 1 wt% based on the total weight of the formulation in order to prevent the high temperature stability of O / P gel formulation from sunflower oil . In addition, the proportion of hydrogenated poly (C6-14 Olefin) for maintaining the formulation stability was set to 30% by weight or more based on the weight of the oil phase part. In order to maintain the hardness and stability of the proper scrub formulations, the proportion of polyol and oil phase except sucrose stearate was kept at about 1: 3.

Both of Formulation Example 1 and Formulation Example 2 may be used alone as sugar raw material as a scrub raw material, in which case the content of sugar may be about 30 to 34% by weight based on the total weight of the formulation.

These formulations are excellent in stability and can be applied to various products such as massage cream, soap, cleansing foam, cleansing gel, cleansing lotion, cleansing cream, and body cleanser.
