Description

Lip cosmetic composition {LIP COSMETIC COMPOSITION}

The present invention relates to a lip cosmetic composition, and more particularly to a lip cosmetic composition of an oil-in-water gel type having excellent moisturizing power.

Lips are thinner than other skin on the body, have no sebaceous glands, and have a poor ability to hold moisture, making them easier to dry. The lip makeup composition used for the lips, such as lipstick, lip gloss, and lip balm, are dispersed in oily substances such as animal and vegetable waxes and ester oils in order to protect the lips while protecting the lips. It is.

Lipsticks generally consist of oils, waxes, and pigment components. Among these components, wax serves to maintain the hardness of the product and to prevent product deformation due to external temperature changes. However, due to the wax component, the color is hard to be clearly expressed, and there is a limit in providing sufficient moisturizing effect to lips that are easy to dry.

Lip gloss contains oily ingredients and can't contain water inside, so it can't supply aqueous and moisturizing ingredients to the lips. That is, lipstick and lip gloss have been used to improve passive moisturization due to a blocking effect in which oily ingredients form an oil film on the lips to prevent evaporation of moisture.

Thus, lip gloss composed of only aqueous components was developed to actively improve the moisturizing properties of the lips, provide excellent color expression, and provide a non-sticky feeling. However, the lip gloss made of only an aqueous component has sufficient disadvantage of supplying water but lacking an oily component, and thus lacks an effect of preventing evaporation of moisture, thereby causing mattes of the lips.

In order to solve the above problems, the present invention provides an oil-in-water gel type lip cosmetic composition containing an oily component that supplies sufficient aqueous and moisturizing ingredients to the lips and prevents evaporation of moisture to keep the lips moist for a long time. do.

Lip cosmetic composition according to embodiments of the present invention may include 0.1 to 0.3 parts by weight of acrylate / alkyl acrylate crosslinked polymer, 0.5 to 1.0 parts by weight of sodium polyacrylate polymer, and 0.4 to 0.6 parts by weight of emulsifier.

The emulsifier may comprise polysorbate 60.

The cosmetic composition may further include 60 to 80 parts by weight of the aqueous component, 5 to 10 parts by weight of the moisturizing component, and 10 to 15 parts by weight of the oily component.

The moisturizing component may include any one of glycerin, 1.3-butylene glycol, sodium hyaluronate, glycerin-26, and mixtures thereof.

The oily component may include any one of an ester liquid oil, a hydrocarbon liquid oil, and a mixture thereof.

The lip cosmetic composition may have an oil-in-water gel type lip tint formulation.

According to embodiments of the present invention, a stable oil-in-water gel type cosmetic composition is formed to supply sufficient moisture to the lips and to help maintain moisture for a long time.

Hereinafter, the present invention will be described in more detail with reference to the following examples. The objects, features and advantages of the present invention will be easily understood by the following embodiments. The present invention is not limited to the embodiments described herein, but may be embodied in other forms. The embodiments disclosed herein are provided so that the disclosure may be thorough and complete, and that those skilled in the art will be able to convey the spirit of the invention to those skilled in the art. Therefore, the present invention should not be limited by the following examples.

Embodiments of the present invention relate to a lip cosmetic composition, and may include 0.1 to 0.3 parts by weight of acrylate / alkyl acrylate crosslinked polymer and 0.5 to 1.0 parts by weight of sodium polyacrylate polymer to form a gel type formulation.

According to embodiments of the present invention, an oily component, an ester liquid liquid, a hydrocarbon liquid liquid, and a mixture thereof, in the polymeric network structure of the acrylate / alkyl acrylate crosslinked polymer and the sodium polyacrylate polymer, are in the form of oil droplets. It is dispersed as While the dispersion system further includes a small amount of both emulsifiers having both hydrophilicity and lipophilic, a stable oil-in-water gel type lip tint cosmetic composition may be made.

In order to increase the emulsion stability of the composition, polysorbate 60 may be used as an emulsifier, and the emulsifier may be included in an amount of 0.4 to 0.6 parts by weight.

The acrylate / alkyl acrylate crosslinked polymer according to embodiments of the present invention may be represented by the following formula (1).

Formula 1

In the acrylate / alkyl acrylate crosslinked polymer represented by Formula 1, particles having a size of 2 to 7 μm are agglomerated in a powder state. When the acrylate / alkyl acrylate crosslinked polymer is hydrated, it has an acidity of pH 3-4. Neutralizing the hydrated polymer with alkali triethanolamine, potassium hydroxide, sodium hydroxide, etc. increases the size to about 20 to 70 μm, and creates a gel state of a polymeric network structure having an inner phase volume of about 1,000 times the powder state.

The oily components are evenly dispersed between the polymeric networks thus formed to maintain a stable state. When applied to the skin, the gel structure is destroyed and water can be felt as if water is bursting.

The sodium polyacrylate polymer may also be used as a gel former to form a polymeric network structure, and when mixed with the acrylate / alkyl acrylate crosslinked polymer, viscosity formation may be easier and the usability may be improved.

According to embodiments of the present invention, the lip cosmetic composition may include purified water as an aqueous component. The purified water may be included in an amount of 60 to 80 parts by weight based on the total composition.

The composition may include 5 to 10 parts by weight of the moisturizing component, 10 to 15 parts by weight of the oily component.

The moisturizing component may be used to give a sufficient moisturizing effect to the lips, and may include glycerin, 1.3-butylene glycol, sodium hyaluronate, glycerin-26, and mixtures thereof.

The oily component may include any one of an ester liquid oil, a hydrocarbon liquid oil, and a mixture thereof, and the composition of the present invention may further include a water-soluble pigment, a discoloration inhibitor, an antioxidant, a neutralizer, and the like.
