Description

Translucent cosmetic composition

The present invention relates to a translucent cosmetic composition with improved stickiness.

Cosmetics such as general lotions, essences, and creams are formulated with solid ingredients such as fatty alcohols and waxes, emulsifiers, and water-soluble polymers, and these are the main ingredients that maintain the stability of the formulation. However, these ingredients are a major factor in giving a heavy and sticky feeling. As fresh and moist products are gaining popularity in the market, products that minimize these oils, emulsifiers and solid ingredients are being released. These products mainly use a small amount of silicone oil and a water-soluble polymer with an alkyl group to improve the stability of the formulation. It is being developed based on the technology to maintain [Non-Patent Document 1]. When this technology is applied, a moisturizing product is made and the appearance of the formulation is translucent, but the use of a polymer is inevitable for some oil formulation and to improve its stability, and the stickiness is still not improved. didn't Water-soluble polymer used as a polymer is an indispensable ingredient in modern cosmetics because it controls the viscosity of the contents in cosmetics to enhance the aesthetic sense and secures the emulsion stability of oil particles and dispersion stability of the dispersion. However, when a water-soluble polymer system is mainly used, it is slippery and has poor absorbency, and as the moisture evaporates, the stickiness of the polymer itself appears strong and the polymer is pushed out. Various types of water-soluble polymers have been synthesized to solve the problems of such water-soluble polymers, but the improvement effect remains at a negligible level and there is no epoch-making breakthrough.

Therefore, the present inventors have studied to find a way to maintain an appropriate amount of oil content to maintain a moisturizing feeling, and to give a more refreshing feeling while stabilizing by mixing a water-soluble polymer. As a result, additional blending of an ethylene oxide polymer and a spherical powder is water-soluble The present invention was completed by confirming that it dramatically lowers the stickiness of the polymer.

Accordingly, an object of the present invention is to provide a translucent cosmetic composition having improved stickiness while containing an appropriate amount of oil.

As a means for solving the above problems, the present invention

It provides a translucent cosmetic composition comprising an ethylene oxide polymer and a spherical powder in a translucent cosmetic composition comprising an oil and a water-soluble polymer.

The translucent cosmetic composition according to the present invention improves the feeling of use of the cosmetic by relieving the stickiness by additionally using an ethylene oxide polymer and a spherical powder as active ingredients for improving the stickiness of the water-soluble polymer.

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

The translucent cosmetic composition according to the present invention is characterized in that it uses conventionally used oil and water-soluble polymer, but additionally blends an ethylene oxide polymer and a spherical powder.

The oil is used as a skin softener and plays an important role in the spreadability and moisturizing feeling of the product, and specifically, dimethicone, cyclopentasiloxane, cyclohexasiloxane, methyltrimethicone, phenyltrimethicone, dimethiconol, cetylethyl It may be at least one selected from the group consisting of hexanoate, caprylic/capric triglyceride, neopentyl glycol dicaprate, hydrogenated castor oil, hydrogenated polydecene and hydrogenated polyisobutene, but this not limited In addition, its content may be 0.1 to 10 parts by weight based on 100 parts by weight of the total cosmetic composition. When its content is less than 0.1 parts by weight, there is a problem in that it does not feel moisturizing and skin suppleness due to the addition of oil, and when it exceeds 10 parts by weight, there is a limitation in emulsifying only with a water-soluble polymer, so there is a problem that an emulsifier must be added separately.

The water-soluble polymer serves to thicken and stabilize oil, and specifically, acrylate crosspolymer, alkyl derivative of acrylate crosspolymer, carbomer, sodium polyacrylate, algin, hydroxyethylcellulose, microcrystalline cellulose, It may be at least one selected from the group consisting of ammonium acryloyldimethyltaurate/vpicopolymer, xanthan gum, and carboxy vinyl polymer, but is not limited thereto. The alkyl derivative of the acrylate crosspolymer may be an acrylate/C10-30 alkyl acrylate crosspolymer.

In addition, the content thereof may be 0.01 parts by weight to 1 part by weight based on 100 parts by weight of the total cosmetic composition. If it is used in less than 0.01 parts by weight, there is a problem in that the stability of the formulation is not ensured, and if it exceeds 1 part by weight, the viscosity of the formulation is excessively increased, so that there is a problem of poor feeling.

The ethylene oxide polymer used in the present invention is used for reducing stickiness caused by the water-soluble polymer used for stabilization purposes, and depending on its molecular weight, PEG-100 (PEG-100), PEG-150 ( At least one selected from PEG-150), PEG-200 (PEG-200) and PEG-240 (PEG-240) may be used, but is not limited thereto.

The ethylene oxide polymer is preferably used in an amount of 0.1 parts by weight to 5 parts by weight based on 100 parts by weight of the total cosmetic composition. When the content thereof is less than 0.1 parts by weight, the stickiness alleviating effect cannot be exhibited, and when it exceeds 5 parts by weight, a problem of skin safety occurs.

As the spherical powder used in the present invention, one or more selected from polymethylsilsesquioxane, polymethyl methacrylate, and silica may be used, but 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 total cosmetic composition. When its content is less than 0.1 parts by weight, the stickiness relief effect is not exhibited, and when it exceeds 3 parts by weight, a problem occurs in that the powder is pushed out when applied to the skin.

The ingredients included in the cosmetic composition of the present invention include ingredients commonly used in cosmetic compositions in addition to the above ingredients, for example, a moisturizing agent, an antioxidant, a stabilizer, a solubilizer, a vitamin, a preservative, a chelating agent, a pigment and a perfume. It may include a phosphorus additive, purified water, and the like. The additive may be used in an amount of 0.1 parts by weight to 10 parts by weight based on 100 parts by weight of the total cosmetic composition. The purified water may be used in an amount of 75 parts by weight to 95 parts by weight or 85 parts by weight to 95 parts by weight based on 100 parts by weight of the total cosmetic composition.

The translucent cosmetic composition of the present invention may be prepared in any formulation conventionally prepared in the art, for example, a solution, suspension, emulsion, paste, gel, cream, lotion, powder, soap, surfactant-containing It may be formulated as cleansing, oil, powder foundation, emulsion foundation, wax foundation and spray, but is not limited thereto. More specifically, it may be prepared in the form of a lotion, lotion, nourishing 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, animal oil, vegetable oil, wax, paraffin, starch, tracanth, cellulose derivative, polyethylene glycol, silicone, bentonite, silica, talc or zinc oxide may be used as a carrier component. can
