This application claims the benefit of the filing date of Korean Patent Application No. 10-2015-0091009, which was filed in the Korean Patent Office on June 26, 2015, and the entire contents of the patent application are included in this specification.

In recent years, women’s interest in cosmetics that relieve skin wrinkles has gradually increased, especially for products that can make lips that are different from the skin in their physiological, physical and biological properties show plump, plump and sexy appearance. The degree gradually increases. According to these requirements, plastic surgery is also implemented, but considering the cost and the pain of skin and flesh, more and more people want to use cosmetics to achieve the above requirements. With the increasing number of consumers who want to use cosmetics to solve this demand Many products are being actively researched to enhance lip volume and lip contour, and related products have been produced one after another.

Generally, lip cosmetics with lip-plumping or wrinkle-improving effects are prepared by mixing waxy substances with oily base materials, and the composition can be divided into the following types. First of all, the first is to maintain the lips by increasing the hardness including candelilla wax, ceresin, carnauba wax, paraffin, wood wax, spermaceti, beeswax, microcrystalline wax and polyethylene. The wax phase component of the appearance of the cosmetic composition. The second type is liquid phase oil containing jojoba oil, squalane, lanolin oil, lanolin derivatives, oils extracted from animals, synthetic ester oils, and silicone oils. Ingredients, the third is blended with functional ingredients for improving the condition of the lips, vitamins, high moisturizing ingredients and antioxidant ingredients, the fourth is a pigmented ingredient composed of organic pigments and inorganic pigments, and the fifth is containing Antioxidants, preservatives, fragrances and nutrients, the sixth is added with pearl pigments and other ingredients.

In addition, conventional substances that provide a plumping effect include warming agents that provide a warming effect, namely, polyols, chili powder, chili flavor, chili juice, capsaicin, and Homocapsaicin. , High dihydro capsaicin, nonanoyl vanillyl amide (nonanoyl vanillyl amide), nonanoyl vanillyl ether, vanillyl alcohol alkyl ether derivatives (Japanese Patent Publication No. 57-9729), isovanillyl alcohol alkyl ether (isovanillyl alcohol alkyl ether) ether), ethyl vanillin alkyl ether, veratryl alcohol derivatives, substituted benzyl alcohol derivatives, substituted benzyl alcohol alkyl ethers, vanillin propylene glycol acetal, ethyl vanillin propylene glycol acetal, Ingredients such as ginger juice, ginger oil, gingerol, gingeron, ginger grass, cinnamon, ginger, rosemary and niacin. Other than warming agents are palmitoyl oligopeptides. (Palmitoyl Oligopeptide; Pal-GHK) and collagen (collagen) ingredients, etc.

However, when using such ingredients with lip-enhancing effects, there is a problem of irritation to the lips and strong stickiness.

In addition, in the conventional lip cosmetic composition, oil-soluble polymers are mainly used in order to exhibit a gloss effect. However, when oil-soluble polymers are used, the sticky feeling is strong and there is a dull feeling.

Moreover, when a water-soluble polymer is used and the dosage form is a lipstick, the hardness of the stick will be reduced, and the compatibility between the components of the lipstick will be significantly reduced, causing the oil to separate from the lipstick, making the appearance of the stick become It is messy and has a high risk of skin irritation because of various emulsifiers used to emulsify water-soluble ingredients (Korea Application Laid-Open Patent No. 10-1999-0009865 (published on February 05, 1999)). Also, although Korean Granted Patent No. 10-1221270 (Announcement on January 11, 2013) discloses a lipstick using an emulsified base containing a water-soluble polymer, the lipstick is composed of a cylindrical core part and surrounding the lipstick. A dual-structure lipstick composed of a core shell part, which does not disclose the content of being used in a single dosage form.

In this regard, the inventor of the present application found that the use of a water-soluble polymer can solve the problems of the existing composition with lip plumping effect characteristics, and at the same time can improve the gloss effect and reduce the fit feeling, thus completing the present invention.

Therefore, the present invention provides a lip cosmetic composition in which the water-soluble polymer is stabilized in the oil phase without an emulsifier, thereby providing a lip plumping effect while improving Gloss and provide a fit lips without stickiness.

In order to achieve the above object, the present invention relates to a water-in-oil lip cosmetic composition comprising a water-soluble polymer, wax and slurry.

Lips are different from existing lip augmentation compositions that cause local pain. The lip cosmetic composition of the present invention exhibits an excellent volume-enhancing effect, does not irritate the lips, has high gloss after application, and does not have a sticky feeling, and The fit feeling is improved, and the feeling in use is very excellent.
