Description

A stick type lip cosmetic composition containing a retinoid

The present invention relates to a stick type lip cosmetic composition, and more particularly, to a stick type lip cosmetic composition which contains a retinoid, a ceramide derivative, a polyglyceryl-n-fatty acid ester and a vegetable triglyceride oil to prevent wrinkles and roughness The present invention relates to a stick type lip cosmetic composition having a skin care function.

Lips are one of the most wrinkled areas of the body and are always exposed to the outside. Particularly, in the case of lips, unlike ordinary skin structure, the stratum corneum is formed extremely thin, the absolute amount of natural moisturizing factor and moisture is small, and the rate of moisture evaporation is several times faster than skin. These factors indicate that the condition of the lips is severely affected by external atmospheric conditions, and accordingly, the cosmetic composition for lips should also contain components different from those of cosmetics introduced into the skin. Until now, cosmetics for lips, however, have been limited to very limited lipstick, lipstick, and lip gloss products, and their ingredients have also failed to keep lip tissue healthy.

Therefore, there is a demand for development of lip cosmetics that can overcome the factors of moisture retention, lack of natural moisturizing factors, and weakening resistance to external climate due to thin skin structure.

In addition, lipstick, which is a main product of point make-up generally applied to the lips, is affected by contact with cosmetic ingredients applied to the lips and changes in the external environment and numerous lip tissues such as defatting and dehydration by food and wrinkles around the lips Particularly, the lips exposed to the weather with severe weather and seasonal changes are dry, the lack of water in the lips and lack of elasticity cause deepening of the formation of the wrinkles of the lips, which causes a serious problem to the lips health. In the past, Cream type pallet type lip color and liquid type lip color product are commercially available. To solve this problem, a stick cosmetic preparation of a lip wrinkle preventing formulation considering lip health has not yet been developed It is true.

Therefore, there has been a demand for the development of a lip cosmetic composition having a pharmacological effect for improving the lips and improving the lips skin elasticity and texture.

As a point makeup cosmetic material used in lip tissue, there are lipsticks containing a large amount of pigment in a stick form and lip crosses in which a pigment is contained in a very small amount or not at all, and organic and inorganic pigments are dispersed in oily substances such as castor oil Wax < / RTI > Specific examples of the components of the lipstick include wax components such as candelilla lead, carnauba lead, and paraffin; Liquid oily components such as castor oil, coconut oil, lanolin oil, and lanolin derivatives; A pigment component composed of organic and inorganic pigments; Antioxidants, fragrances, preservatives, and the like.

However, it is known that lanolin and lanolin derivatives have skin adverse effects for certain populations. In addition, the pigment contains trace amounts of harmful heavy metals such as lead and arsenic. Thus, these factors are the main harmful factors to the lips health, and the lips are constantly facing roughness and wrinkles.

Therefore, conventionally, lip cosmetic compositions containing retinol ester derivatives, ascorbic acid and derivatives, tocopherol and derivatives, riboflavin and derivatives thereof, and oils as lip cosmetics for preventing wrinkles of the lips have been disclosed in Japanese Patent Application Laid-Open No. 4-117317 Lt; / RTI > However, in the lip cosmetic composition of Japanese Patent Application Laid-Open No. 4-117317, the retinoid component is a component completely different from retinol as a retinol fatty acid ester and can not function to prevent wrinkles of retinol itself because it is a component that has already lost its activity, , Ascorbic acid, tocopherol, lanolin, riboflavin and derivatives thereof are insufficient in terms of stability problems and effects when they are introduced into a simple oily base, so that they are not effective in preventing the wrinkles of the lips and the roughness of the lips. In addition, cosmetic preparations containing retinol, an organic solvent, an emulsifying agent and an aqueous alkaline solution to stabilize retinol, which can be used as wrinkle preventing cream, lip balm or acne remedy, are known in French Patent No. 93-15862, It is not used as a lip cosmetic composition but has an ointment or cream type formulation intended to prevent the wrinkles of the lips while reducing the burden on the lips.

Accordingly, the present inventors have studied to develop a stick type lip cosmetic composition which can prevent the wrinkles and roughness of the lips, and it has been pointed out that the retinoid ingredient is effective for skin aged by wrinkles, roughness, dryness, Thereby completing the present invention.

Accordingly, an object of the present invention is to provide a stick type lip cosmetic composition which can reduce lip stimulation and prevent lip roughness and wrinkles.

In order to achieve the above-mentioned object, the stick type lip cosmetic composition of the present invention is characterized by containing the retinoid in an amount of 0.0001 to 10% by weight based on the total weight of the composition.

The stick type lip cosmetic composition of the present invention may further contain 0.001 to 20 wt% of a ceramide derivative, 5.0 to 70 wt% of a polyglyceryl-n-fatty acid ester, and 0.1 to 80 wt% of a vegetable triglyceride oil, based on the total weight of the composition .

Hereinafter, the present invention will be described more specifically.

In the lip cosmetic composition of the present invention, the retinoid is retinol, retinic acid, retinaldehyde, or a mixture thereof, and is effective for skin aged by wrinkles, roughness, dryness, abnormal keratinization and the like. Particularly, in the present invention, the retinoid is used to form a healthy and elastic lip tissue through protein synthesis of the dermis through a thin lip membrane, and the content thereof is in the range of 0.0001 to 10.0% by weight based on the total weight of the composition Is used.

The ceramide derivative used in the present invention is a substance produced by alkalizing a fatty acid in an LCB (Long Chain sphingoid base) or by the catalytic action of a natural enzyme, It maintains the stability of retinoids in the cosmetic itself and forms a double layer like that in living tissues in lips skin to effectively block ineffective factors inside and outside the lips. It keeps the lips skin more effectively and regulates retinoid skin penetration And fulfill the function of moisturizing. Here, the fatty acid includes both _C8-60 saturated, unsaturated and structural isomers, and each of the fatty acids may contain 0 to 2 hydroxy groups.

That is, the ceramide derivative used in the stick type lip cosmetic composition of the present invention is produced by the above-mentioned method and its kind is not particularly limited.
