Description

Eye Make-up Cosmetic Composition with excellent volume and curling durability}

The present invention relates to a makeup cosmetic composition, specifically, to an eye makeup cosmetic composition capable of providing excellent volume and curling durability.

Mascara is applied to hairs such as eyebrows and eyelashes to compensate for the disadvantages of the shape or to give beauty to the eyes. The characteristics required of mascara, especially mascara applied to the eyelashes, provide volume when applied, provide curling and long lash functions, apply evenly so as not to spread easily in sweat, tears, and oil, so as not to fly powder, and there is no burden when used, and microorganisms It is less likely to be contaminated and should be easily removed when washing the face.

Specifically, the mascara may be prepared in an emulsified type and an oil dispersion type. The emulsified type may be a water-in-oil type or an oil-in-water type, and the oil dispersion type may be a type in which a pigment and a film forming agent are dispersed in oil. Depending on which formulation it is made of, only some of the above-described characteristics may be satisfied.

In the case of water-type mascara, it is easily erased by moisture, sweat, tears, etc., but the water-type type is mainly developed for convenience in use, such as quick drying. Korean Patent Registration No. 10-1118363 and Patent Publication No. 10-2019-0141939 also disclose an oil-in-water mascara composition with improved properties. In the case of water-in-oil type mascara, since the outer layer is oil, it dries slowly, so it has the advantage of being applied evenly even if applied for a long time. In addition, since both the water-in-water type and the water-in-oil type formulation are completed through emulsification of the oil phase and the water phase, the use of an emulsifier is the basis, and when such an emulsifier is insufficient, the formulation is broken and stability problems may occur. In addition, there may be cases in which a change in hardness appears over time.

In the case of oil-dispersion type mascara, since it is prepared by dispersing wax, powder, polymer, etc. in an oil phase and hardening it, basically, there are many cases where the feeling of slippery oil remains strong. In addition, the drying speed is slow compared to emulsified formulations, so it takes a long time to produce a cosmetic effect, and it is not easy to have strong curling power and curling durability. Accordingly, drying speed and curling power are imparted by using various silicone acrylate films. In addition, oil-dispersion type mascara has a problem in that it is difficult to impart a sense of volume that enriches the eyelashes due to the characteristics of oils with low surface tension.

In order to solve the above problems, an object of the present invention is to provide an oil dispersion type eye makeup cosmetic composition with improved curling power and volume.

The present invention provides an oil dispersion type eye makeup cosmetic composition. Specifically, the present invention is an oil-dispersible composition comprising an oil phase part, a powder part, and a film former, wherein the film former contains silicone acrylate and aluminum distearate. To provide an oil dispersion type eye makeup cosmetic composition.

In the cosmetic composition of the present invention, the silicone acrylate is characterized by comprising a butyl acrylate/hydroxypropyl dimethicone acrylate copolymer (Butyl Acrylate/Hydroxypropyl Dimethicone Acrylate Copolymer).

In the cosmetic composition of the present invention, the butyl acrylate/hydroxypropyl dimethicone acrylate copolymer is characterized in that it is included in 10 to 40% by weight based on the total weight of the composition.

In the cosmetic composition of the present invention, the aluminum distearate is characterized in that it is included in 0.5 to 4% by weight based on the total weight of the composition.

In the cosmetic composition of the present invention, a wax component may be additionally included in the oil phase part. The wax is Carnauba Wax, Candelilla Wax, Polyethylene Wax, Lanolin Wax, Paraffin Wax, Bees Wax, Sucrose Fatty Acid Ester (Sucrose Fatty Acid Ester), microcrystalline wax, or a mixture thereof.

The eye makeup cosmetic composition according to the present invention can provide a flexible yet strong curling power and durability, which have not been seen in conventional oil-dispersed formulations, and at the same time provide an excellent sense of volume.

Hereinafter, the present invention will be described in detail so that those skilled in the art can easily practice it with reference to the accompanying technology.

[Example]

1. Sensory evaluation of the cosmetic composition for mascara according to the type of silicone film

(1) Preparation of the cosmetic composition of Example 1 and Comparative Example 1

A cosmetic composition for mascara containing the composition (unit: weight%) of Table 1 below was prepared.

i) Component 2 of Table 1 below was dissolved at 90° C., and then added to Component 1 and stirred. ii) After that, components 3 and 4 were added to i) and stirred. iii) Component 5 (Comparative Example 1) or 6 (Example 1) was added to ii), and after stirring, the mixture was cooled to 30°C.

(2) Sensory evaluation of the cosmetic compositions of Example 1 and Comparative Example 1

Sensory evaluation was conducted for Example 1 and Comparative Example 1 prepared according to the composition of Table 1 above. Twenty women aged 20 to 40 were evaluated for applicability, application amount (volume), chart surface (smoothness), curling power, drying speed, smearing under the eyes, and curling durability as shown in Table 2 below. . For each item, a score of 1 to 10 was given, and 8 points or more was marked as very good, 6 to 8 points as good, 3 to 6 points as average, and less than 3 points as poor.

As can be seen from Table 2, when trimethylsiloxysilicate, which is a silicone film, is used, one of the strengths is that it exhibits excellent properties in curling power, drying speed, smearing, etc., but the spreadability, amount of application, and smoothness of the applied surface are somewhat poor. You can check.

Looking at Example 1, although the butyl acrylate/hydroxypropyl dimethicone acrylate copolymer was slightly inferior to trimethylsiloxysilicate in terms of curling power and drying speed, it received generally good reviews in all characteristics, and in terms of spreadability, You can see that it has received very good reviews.

Accordingly, it was confirmed that by including the butyl acrylate/hydroxypropyl dimethicone acrylate copolymer, a smooth and flexible oil-dispersible mascara formulation with good overall sensory evaluation could be provided.

2. Sensory evaluation of cosmetic composition for mascara according to the content of butyl acrylate/hydroxypropyl dimethicone acrylate copolymer

(1) Preparation of cosmetic compositions of Examples 1 to 4 and Comparative Examples 2 to 3

A cosmetic composition for mascara containing the composition (unit: weight%) of Table 3 below was prepared.

i) Component 2 of Table 3 below was dissolved at 90° C., and then added to Component 1 and stirred. ii) After that, components 3 and 4 were added to i) and stirred. iii) Component 5 was added to ii), stirred, and then cooled to 30°C.

(2) Sensory evaluation of the cosmetic compositions of Examples 1 to 4 and Comparative Examples 2 to 3

Sensory evaluation was conducted on Examples 1 to 4 and Comparative Examples 2 to 3 prepared according to the composition of Table 3 above. Similarly, 20 women aged 20 to 40 were targeted, and as shown in Table 4 below, applicability, application amount (volume power), chart surface (smoothness), curling power, drying speed, smearing under the eyes, curling persistence To evaluate the items did For each item, a score of 1 to 10 was given, and 8 points or more was marked as very good, 6 to 8 points as good, 3 to 6 points as average, and less than 3 points as poor.

As can be seen from Table 4, a difference occurred in sensory evaluations such as curling power, durability, and spreadability according to the content of component 5, butyl acrylate/hydroxypropyl dimethicone acrylate copolymer. In the case of Comparative Example 2 containing 5% by weight of butyl acrylate/hydroxypropyl dimethicone acrylate copolymer, it was confirmed that spreadability and curling durability were low, and through Comparative Example 3, drying speed, smearing, curling power, curling durability, etc. It can be seen that most of these characteristics give poor results. In the case of Comparative Example 3 containing more than 40% by weight of butyl acrylate/hydroxypropyl dimethicone acrylate copolymer, the characteristic of the sticky polymer was prominent, resulting in the overall balance of the formulation collapsing.

3. Sensory evaluation of cosmetic composition for mascara according to aluminum stearate content

(1) Preparation of cosmetic compositions of Examples 5 to 9 and Comparative Examples 4 to 5

A cosmetic composition for mascara containing the composition (unit: weight%) of Table 5 below was prepared.
