Description

Oil gel type anhydrous cosmetic composition < RTI ID = 0.0 >

More specifically, the present invention relates to an anhydrous cosmetic composition on an oil gel, which is safe to the skin, has excellent adhesion and gives a feeling of soft feeling, has excellent stability over time, To a cosmetic composition.

The skin is an important body that is responsible for various physiological functions such as barrier function, body temperature control and excretion, which protects the human body from the external environment and prevents the internal moisture and oil components from leaking out. However, skin stress due to various environmental pollution, deterioration of cell function due to aging, and photoaging due to ultraviolet rays cause skin nourishment and moisture to be insufficient and metabolism is not smooth and aging is promoted.

To delay the aging of the skin, various cosmetic compositions having excellent moisture retention have been developed. As the moisturizing agent, a polyol such as glycerin, butylene glycol, propylene glycol, polyethenylene glycol, or sorbitol is used as the component for increasing the moisture resistance. The polyol has a capability of containing water But it has a disadvantage that it has poor persistence to moisturizing effect and has a heavy stickiness when applied to the skin or a rough and damp feeling. On the other hand, oils forming a closed membrane generally have high moisture retention, but they have disadvantages such as stickiness, slow absorption, and shine. In order to overcome the disadvantages of such components and to emphasize their merits, a cosmetic composition and a formulation technique utilizing various components have been developed and research has been conducted to give new functions, appearance, and texture to cosmetics. Particularly, the anhydrous formulation is a stabilized formulation (Patent No. 10-1404969, 10-0811465) using a polyol having excellent water-containing ability and an oil having excellent moisture retention property, However, it still has problems such as instability due to aging and feeling of heavy and frustrating feeling.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above problems and to provide an anhydrous oil gel phase in which polyol and oil are stabilized by using lecithin, which is safe to skin, To provide an anhydrous oil gel cosmetic composition effective for percutaneous absorption of an effective ingredient.

In order to solve the above problems, the present invention provides an oil-gel-like anhydrous cosmetic composition comprising a hydrogenetric lecithin, an oil, and a polyol, preferably an oil comprising one or more other polyols together with polyethylene glycol in the polyol Thereby providing a gel-like anhydrous cosmetic composition.

That is, the inventors of the present invention have found that when polyethylene glycol is used together with hydrogenated lecithin, the stability of an oil-gel-like anhydrous cosmetic composition is increased, the skin-tightness is excellent and the feeling of use is excellent, And the present invention was completed.

In the oil-gel-like anhydrous cosmetic composition according to the present invention, hydrogenated lecithin is converted into saturated fatty acid by hydrogenation using lecithin as a catalyst, and unlike lecithin, its stability is improved, (Kutz G., Biehl P., Waldmann-Laue M., Jackwerth B., SOFW-Journal, 123, 145-149 (1997)).

The hydrogenated lecithin may be contained in an amount of 1 to 30% by weight, more preferably 5 to 20% by weight, based on the total weight of the anhydrous oil gel cosmetic composition. If it is less than 1% by weight, it is difficult to achieve the object of the present invention. If it exceeds 30% by weight, the stability of the product may be deteriorated.

The polyol includes polyethylene glycol and may be used together with polyethylene glycol such as glycerin, dipropylene glycol, butyleneglycol, pentylene glycol, methylpropanediol, sorbitol, diglycerin, erythritol, pentaerythritol, -10, polyglycerin-3, polyglycerin-4, polyglycerin-6, polyglycerin-10, polyglycerin-20, polyglycerin-40, sorbes-5, sorbes-6, sorbes- Mannitol, lactitol, lactose, dihydroxypropyl PG-glucoside, dithiaoctanediol, fructose, glucamine, methylglucamine, glucose, 1, , At least one selected from the group consisting of 2,6-hexanediol, methylglucose-10, methylglucose-20, ozonized glycerin, phytantriol, thioglycerin, traitol, trimethylolpropane and xylitol include Can.

The polyethylene glycol may have an average molecular weight of 200 to 600, preferably PEG (PEG) -8 having a molecular weight of 400.

The content of the polyol is preferably 2 to 50 parts by weight, more preferably 5 to 40 parts by weight, based on 100 parts by weight of the anhydrous oil gel cosmetic composition. If the amount is less than 2 parts by weight, there may be a problem in high-temperature stability with time, and when it is more than 50 parts by weight, it is difficult to expect a desirable feeling.

In the oil-gel-like anhydrous cosmetic composition according to the present invention, the amount of polyol excluding polyethylene glycol is preferably 0.1 to 30 parts by weight, more preferably 0.5 to 20 parts by weight. When the amount is less than 0.5 part by weight, the effect is insignificant. When the amount is more than 20 parts by weight, the stability of the preparation is deteriorated.

Examples of the polyols include glycerin, dipropylene glycol, butyleneglycol, pentylene glycol, methylpropanediol, sorbitol, diglycerin, erythritol, pentaerythritol, polybutylene glycol-10, polyglycerin -3, polyglycerin-4, polyglycerin-6, polyglycerin-10, polyglycerin-20, polyglycerin-40, sorbes-5, sorbes-6, sorbes-20, sorbes- -40, inositol, maltitol, mannan, mannitol, mannose, lactitol, lactose, dihydroxypropyl PG-glucoside, dithiaoctanediol, fructose, glucamine, methylglucamine, glucose, At least one selected from the group consisting of hexanediol, hexanediol, methylglycine-10, methylglucose-20, ozonized glycerin, phytantriol, thioglycerin, traceol, trimethylolpropane and xylitol. In the present invention, it has been found out that there is a considerable difference between stability and feeling of use depending on which polyol mixture is used when the other components are the same in an oil-gel-like anhydrous cosmetic composition. Particularly in the combination of polyethylene glycol and dipropylene glycol, It was confirmed that it was easy to achieve the desired effect.

The embodiments of the present invention are provided by way of example to facilitate a specific understanding of the present invention.

<Example 1-3 and Comparative Example 1-5>

The cosmetic compositions of Examples 1-3 and Comparative Examples 1-5 were prepared according to the compositions shown in Table 1 below. In Example 1-3, the content of the hydrogenated lecithin was different from the content of the oil and the content of the polyol. In Comparative Example 1, no hydrogenated lecithin was added. In Comparative Example 2, oil was used. In Comparative Example 3, Was not added. In Comparative Example 4, oil and polyethene were added to dissolve the genistein, and in Comparative Example 5, the gene-8 and polymer were added to dissolve the genistein.

According to the respective compositions shown in Table 1, the water phase and the oil phase were completely dissolved by heating at 80 to 90 占 폚, and then the aqueous phase was slowly added with stirring to the disperser and cooled to room temperature.

Experimental Example  1. Skin permeability verification

The permeability of the skin was checked using a Franz glass cell (Standard diameter 9 mm, Receiver 5 ml, Permegear).

Specifically, porcine skin (0.7 mm in thickness, Medikinetics) coated with 50 mg of each of Examples 1-3 and Comparative Examples 1-5 was placed between the upper and lower ends of the glass cell, and 500 ul and 5 ml TBS (50 mM Tris pH 7.5, 150 mM NaCl) was added. After 8 hours, the porcine skin tissue was disrupted, and the amount of the genistein was quantitatively analyzed and the transmittance was shown in Table 2 below.

As a result of the percutaneous absorption test in the above Table 2, it was found that excellent results were obtained in the formulations in which all of the hydrogenconed lecithin, oil, and phage-8 were added as in Examples 1 to 3, Absorption results were relatively low.

Experimental Example  2. First skin irritation test ( Closed-pore experiment )

In order to examine skin irritation, 15 μg of each sample was applied to the arm for 50 healthy male and female subjects for 24 hours, and after 4 hours had elapsed after removing the pin chamber, Changes in skin condition were visually observed and the results are shown in Table 5 below.

In this case, the criterion is '-' when there is no erythema or unusual phenomenon, '+ -' when it is slightly reddish from the periphery, '+' when it is more reddish than the periphery, &Quot; ++ &quot;. On the other hand, the degree of stimulus is calculated and shown by the following equation (1) in order to show the determination result based on the above-mentioned criterion as a relative value.

[Equation 1]

As a result of the stimulus (safety) test in Table 3, it was observed that the stimulation was comparatively low in each of the Examples and Comparative Example 1, while Comparative Examples 2 to 5 were observed to exhibit relatively high stimulation.

Experimental Example  3. Feeling  evaluation

After preparing a cosmetic composition using the compositions having the compositions of the above Examples and Comparative Examples, 20 panelists from 20 to 40 years old judged the sensation of use by sensory evaluation. At this time, the feeling feeling score was rated as 5 points, 3 points as an excellent score, 0 points as an average score, -3 points as a bad score, and -5 points as a very bad score. Evaluation scores of each individual were calculated according to the following formula (1), and the final results are shown in Table 3 below.

&Quot; (2) &quot;

As can be seen from the evaluation results of the examples and comparative examples shown in Table 4, in general, the examples were evaluated to have excellent feeling in use as compared with the comparative examples.

Experimental Example  4. Stability evaluation

The stability was evaluated by observing the state of the product after storage for 1 month at 50 ° C, 0 ° C, 40 ° C and 45 ° C cycle chamber (-10 ° C → 45 ° C → -10 ° C). The evaluation score was rated as ⊚ when it was very good, O when it was good, Δ when it was good, X when the separation and sweating occurred a little, and XX when the separation and sweating occurred severely.

As shown in Table 5 below, the results of Comparative Examples 1 to 5 are more unstable than those of Examples. In particular, it can be seen that the cyclic chamber and the unstable phenomenon appear at higher temperatures. In addition, precipitation of the genistein was observed in Comparative Examples 1 to 5.
