Description

TECHNICAL FIELD The present invention relates to a mascara cosmetic composition with improved makeup lasting power, and more specifically, a mascara containing trimethylsiloxysilicate and amodimethicone, suppressing bleeding, and having improved cleansing effect and curl retention power. It relates to a cosmetic composition.

The purpose of mascara is to apply it to the eyelashes to thicken and curl the eyelashes, thereby making the eyes clearer. Early mascara was a solid mixture of sodium stearate and carbon black, and was applied with a wet brush. , is an emulsified form obtained by mixing a highly safe polymer with suitable plasticity. This is because the emulsified form of mascara is very advantageous in imparting mascara-specific functions such as volumizing power, curling power, and longevity.

Also, consumers who desire longer, darker eyelashes have traditionally used false eyelashes that adhere to their natural eyelashes with an adhesive or have applied expensive eyelash extensions. As an alternative, various mascara products are gaining popularity. Nevertheless, some eyelashes may have too few lashes for a general-purpose volume mascara to be effective. On the other hand, even women with thick eyelashes may desire more than a given cosmetic effect with their preferred mascara. The attributes that mascara products are expected to possess include the ability to not clump or flake, to give the lashes a fuller appearance, and to make the lashes darker, thicker and longer. It is also preferred that the product is water and/or smudge resistant but not difficult to remove. The cosmetic industry has responded to these demands by providing mascara compositions containing fibers, waxes and/or bulking or filler agents, but without reducing the processability of the dosage form or the product into a brush. There is a limit to the amount of ingredients that can be added to the formulation without interfering with both loading the product and transferring the product from the brush to the lashes. There is still a need to formulate a cosmetic composition that adheres well to the eyelashes and eyebrows in order to achieve the purpose of reducing bleeding.

Against this background, the present inventors have made diligent efforts to produce a mascara cosmetic composition with improved bleeding. After confirming the improvement, the present invention was completed.

The present inventors have made diligent efforts to develop a cosmetic composition with improved curl retention and bleeding. As a result, the mascara cosmetic composition of the present invention has high adhesion to keratin fibers (eyelashes/hair), The inventors have confirmed that excellent effects such as formation of a uniform surface, high curl retention, and less clumping and bleeding have been obtained, leading to the completion of the present invention.

An object of the present invention is to provide a cosmetic composition with improved curl retention and bleeding. Specifically, the present invention provides a mascara cosmetic composition containing trimethylsiloxysilicate and amodimethicone as active ingredients.

The mascara cosmetic composition according to the present invention not only has effects such as high adhesion to keratin fibers (eyelashes/hair), formation of a uniform surface, high curl retention, and less clumping and bleeding, but also cleansing. can also facilitate

These will be specifically described below. It should be noted that each description and embodiment disclosed in the present invention also applies to other descriptions and embodiments, respectively. That is, the present invention includes all combinations of various elements disclosed in the present invention. Moreover, the present invention is not limited to the following specific description.

One aspect of the present invention for achieving the above object provides a mascara cosmetic composition containing trimethylsiloxysilicate and amodimethicone as active ingredients.

Specifically, it is a cosmetic composition in which clumps and bleeding after application of a mascara product are improved, i.e., a cosmetic composition in which transfer is suppressed, curl retention of eyelashes and eyebrows is improved, and adhesion is improved. can be provided.

In the present invention, trimethylsiloxysilicate and amodimethicone, which are active ingredients of the mascara cosmetic composition, serve as film-forming agents.

Trimethylsiloxysilicate, which is a kind of silicon, and/or rosin acid-based resins are generally used to improve durability, but oil bleeding has not yet been improved. In addition, there is a sticky feeling, and the film tends to crumble after drying, causing the mascara to fall under the eyes in a powdery state. Therefore, in the present invention, since trimethylsiloxysilicate and amodimethicone are included as active ingredients at the same time, the hydrophilic amine group of amodimethicone provides resistance to oil, and exhibits cosmetic longevity and anti-bleeding effects. can.

Also, conventional mascara cosmetic compositions have used electrostatic forces to increase adhesion to the eyelashes. In anionic eyelashes, cationic polymers and binding polymers have been used to improve powder adhesion and maximize eyelash volume and cosmetic effects. However, even if the adhesion to the eyelashes is increased by using the electrostatic force, the particulate matter tends to come off, resulting in bleeding under the eyes and scattering of powder. Therefore, since the present invention contains both trimethylsiloxysilicate and amodimethicone as active ingredients, the amino group of amodimethicone, which is a non-volatile oil, is absorbed by the keratin substance, namely the weakly acidic surface of the eyelash, by "ionic attraction". By strongly interacting, a film having excellent adhesion to the eyelashes can be formed, and the film adhesion can be improved.

Therefore, since the present invention contains both trimethylsiloxysilicate and amodimethicone as active ingredients, a cosmetic composition having improved oil resistance, sebum resistance, and adhesion to eyelashes can be obtained.

Trimethylsiloxysilicate, which is an oily coating agent used under the above conditions, is not limited to this, and may be a coating agent (polymer/resin) made from polydimethylsiloxane, such as a polydimethylsiloxane-based It may be used by mixing with a coating agent (polymer/resin).

Confirmation of adhesion of mascara to eyelashes In order to confirm the adhesion of the mascara cosmetic composition of the present invention to eyelashes, Experimental Examples 1 and 3 produced in the above production examples were applied to the hair, and the weight was applied after external rubbing. Changes and surface damage were observed. A specific experimental method is as follows.

Experimental Examples 1 and 3 were applied to hair similar to eyelashes and allowed to dry, after which external friction was applied, and the weight and surface damage of the mascara applied to the hair were compared with the initial one.

However, Experimental Example 2, which was prepared in the above Preparation Example, contained only amodimethicone as an active ingredient, making the dosage form unstable due to stickiness and aggregation of the sample, making the experiment difficult, so it was excluded from the final experiment.

As a result, in Experimental Example 3, which contains both trimethylsiloxysilicate and amodimethicone as active ingredients, the adhesion to the hair is strong, the surface is not damaged by external friction, and a uniform surface is formed. Objects did not fall easily, and the amount of weight change was small. In Experimental Example 1, the surface damaged by external friction was observed, and it was confirmed that the amount of weight change was larger than in Experimental Example 3 (FIGS. 1 and 2).

Therefore, it was confirmed that the mascara cosmetic composition of the present invention containing both trimethylsiloxysilicate and amodimethicone as active ingredients has an effect of increasing adhesion to eyebrows and eyelashes.

Evaluation of curl reduction rate In order to confirm the curling power of the cosmetic mascara composition of the present invention, the mascara cosmetic composition of Experimental Example 3 produced in the above production example was applied to nylon fibers, and the angle change rate of nylon fibers was measured. observed. A specific experimental method is as follows.

A predetermined angle was formed on the nylon fiber, then the mascara cosmetic composition of Experimental Example 3 was applied the same number of times, and the angle change of the nylon fiber was measured after 6 hours.

As shown in FIG. 3, Experimental Example 3, which contains both trimethylsiloxysilicate and amodimethicone, has a curl reduction rate of -10.25%. Since the curl reduction rate value of Experimental Example 3 was within -20%, it was confirmed that the curl retention was excellent (Fig. 3).

Therefore, it was confirmed that the mascara cosmetic composition of the present invention containing both trimethylsiloxysilicate and amodimethicone as active ingredients has a curl retention effect.

Bleeding test In order to confirm the bleeding property of the cosmetic mascara composition of the present invention, the mascara cosmetic compositions of Experimental Examples 1 to 3 produced in the above production examples were applied on glass, and repeated with artificial sebum. Bleeding after exercise was observed. A specific experimental method is as follows.

The coating was applied onto glass, dried, and then wetted with 0.2 g of artificial sebum. A white paper was placed on the coating and a weight of 200 g was placed thereon, and after 30 repetitions of motion, the color difference (L value) and area of the mascara coating attached to the white paper were calculated.

As shown in the results shown in FIG. 3, from Experimental Example 1 containing trimethylsiloxysilicate alone and Experimental Example 2 containing amodimethicone alone, in Experimental Example 3 containing trimethylsiloxysilicate and amodimethicone at the same time, artificial sebum It was confirmed that the bleeding area was the smallest and the bleeding strength was the highest (Fig. 3).
