Description

Translucent cosmetic composition [0002]

The present invention relates to a semi-transparent cosmetic composition having improved stickiness.

Common cosmetics such as lotions, essences, and creams are blended with solid components such as fatty alcohols and waxes, emulsifiers, and water-soluble polymers, which are main ingredients for maintaining the stability of the formulation. But these ingredients are a major factor in feeling heavy and sticky. These products are mainly based on small amount of silicone oil and water-soluble polymer added with alkyl group, so that the stability of the formulation is improved. [Non-Patent Document 1]. This technique has the characteristic of producing a moisture-sensitive product and the appearance of the formulation is translucent. However, in order to improve the stability of the oil composition and some degree of use, the polymer is inevitably used, and the stickiness is still not improved I did. The water-soluble polymer used as a polymer is an indispensable ingredient in modern cosmetics because it controls the viscosity of the contents in cosmetics, thereby enhancing the aesthetic sense and securing the emulsion stability of the oil particles and the dispersion stability of the dispersion. However, when a water-soluble polymer system is mainly used, it is slippery, has poor water absorption, and moisture is evaporated, resulting in strong stickiness of the polymer itself, and there is a problem that the polymer is pushed out. Various types of water-soluble polymers have been synthesized to solve the problems of the water-soluble polymer, but the improvement effect remains at a mere level, and breakthrough breakthroughs are not disclosed.

The inventors of the present invention have studied to find a method of maintaining an appropriate amount of oil content and maintaining a moisturizing feel and providing a feeling of freshness as the water-soluble polymer is mixed and stabilized. As a result, it has been found that the addition of the ethylene oxide polymer and the spherical powder, And that the stickiness of the polymer is remarkably lowered, thereby completing the present invention.

Accordingly, an object of the present invention is to provide a semi-transparent cosmetic composition containing an appropriate amount of oil and having improved stickiness.

As means for solving the above problems,

A translucent cosmetic composition comprising an oil and a water-soluble polymer is further provided with a translucent cosmetic composition further comprising an ethylene oxide polymer and a spherical powder.

The semi-transparent cosmetic composition according to the present invention improves tactile feeling by alleviating tackiness by using an ethylene oxide polymer and a spherical powder as an effective ingredient for improving stickiness of a water-soluble polymer.

The present invention relates to a semi-transparent cosmetic composition comprising an ethylene oxide polymer and a spherical powder.

The semi-transparent cosmetic composition according to the present invention is characterized in that ethylene oxide polymer and spherical powder are further blended by using the oil and water-soluble polymer which have been used in the past.

The oil is used as a skin softening agent and plays an important role in the spreadability and moisturizing properties of the product. Specifically, it is preferable to use dimethicone, cyclopentasiloxane, cyclohexasiloxane, methyltrimethicone, phenyltrimethicone, dimethicone, But may be at least one selected from the group consisting of hexanoate, caprylic / capric triglyceride, neopentylglycol dicaprate, hydrogenated castor oil, hydrogenated polydecene, and hydrogenated polyisobutene, It is not limited. The content thereof may be 0.1 part by weight to 10 parts by weight based on 100 parts by weight of the whole cosmetic composition. When the content of the water-soluble polymer is less than 0.1 part by weight, there is a problem that a feeling of moisturizing and skin softness can not be felt due to the addition of oil. When the content is more than 10 parts by weight, emulsification with water-soluble polymers is limited.

The water-soluble polymer has the function of increasing and stabilizing the oil, and more specifically, an acrylate crosspolymer, an alkyl derivative of an acrylate crosspolymer, a carbomer, sodium polyacrylate, algin, hydroxyethylcellulose, microcrystalline cellulose, But are not limited to, ammonium acryloyldimethyltaurate / vpicopolymer, xanthan gum, and carboxyvinyl polymer. The alkyl derivative of the acrylate crosspolymer may be an acrylate / C10-30 alkyl acrylate crosspolymer.

The content thereof may be 0.01 part by weight to 1 part by weight based on 100 parts by weight of the whole cosmetic composition. If it is used in an amount of less than 0.01 part by weight, there is a problem that the stability of the formulation can not be ensured. If the amount is more than 1 part by weight, the viscosity of the formulation becomes excessively high.

The ethylene oxide polymer used in the present invention is used for reducing the stickiness caused by the water-soluble polymer used for stabilization purposes. The ethylene oxide polymer used in the present invention is preferably used in the present invention. Examples of the ethylene oxide polymer include PEG-100 (PEG-100) (PEG-150), PEG-200 (PEG-200), and PEG-240 (PEG-240).

The ethylene oxide polymer is preferably used in an amount of 0.1 part by weight to 5 parts by weight based on 100 parts by weight of the whole cosmetic composition. When the content thereof is less than 0.1 part by weight, the tackiness-mitigating effect is not exhibited. When the content is more than 5 parts by weight, a problem of skin safety occurs.

As the spherical powder used in the present invention, at least one selected from polymethylsilsesquioxane, polymethyl methacrylate and silica may be used, but the present invention is not limited thereto.

The spherical powder is preferably used in an amount of 0.1 to 3 parts by weight based on 100 parts by weight of the whole cosmetic composition. When the content thereof is less than 0.1 part by weight, the tackiness relaxation effect is not exhibited. When the content is more than 3 parts by weight, the powder is pushed out during application of the skin.

The components included in the cosmetic composition of the present invention include components commonly used in cosmetic compositions in addition to the components described above and can be used in a conventional manner such as a moisturizer, an antioxidant, a stabilizer, a solubilizer, a vitamin, an antiseptic, a chelating agent, Phosphorous additive, purified water, and the like. The additive may be used in an amount of 0.1 part by weight to 10 parts by weight based on 100 parts by weight of the whole cosmetic composition. The purified water may be used in an amount of 75 to 95 parts by weight or 85 to 95 parts by weight based on 100 parts by weight of the entire cosmetic composition.

The semitransparent cosmetic composition of the present invention can be prepared in any form conventionally produced in the art, and can be, for example, a solution, a suspension, an emulsion, a paste, a gel, a cream, a lotion, a powder, a soap, But are not limited to, cleansing, oil, powder foundation, emulsion foundation, wax foundation, and spray. More specifically, it can be prepared in the form of lotion, lotion, nutritional cream, massage cream, essence, eye cream, cleansing cream, cleansing foam, cleansing water, pack, spray, foundation or powder.

When the formulation of the present invention is a paste, cream or gel, an animal oil, vegetable oil, wax, paraffin, starch, tracer, cellulose derivative, polyethylene glycol, silicone, bentonite, silica, talc or zinc oxide may be used as the carrier component .
