Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a lip cosmetic,
More specifically, the present invention relates to a lip cosmetic having excellent usability and adhesive force and having an effect of preventing bleeding.

[0002]

2. Description of the Related Art Conventionally, liquid oils, waxes, and the like have been used as raw materials for oils for lip cosmetics. Examples of the liquid oil include hydrocarbons, esters, higher alcohols, and silicone oils. Examples of the wax include animal waxes such as beeswax, vegetable waxes such as candelilla wax, and petroleum waxes such as paraffin wax. In order to improve usability in lip cosmetics,
In order to increase the blending amount of liquid oils such as hydrocarbons and silicone oils and to improve the adhesion, liquid oils having high adhesion such as esters have been increased. Further, in order to improve the effect of preventing bleeding, the amounts of various waxes such as candelilla wax and powders are increased.

[0003]

However, according to the conventional method, it is necessary to increase the amount of liquid oil and to reduce the amount of wax or liquid oil having high adhesion, mainly in view of improvement of usability. However, as a result, not only the stability is lowered, but also it becomes difficult to secure the adhesive force and the effect of preventing bleeding. On the other hand, when focusing on the improvement of the adhesive force, a large amount of liquid oil having high adhesiveness such as a glycerin derivative is blended, and as a result, the usability becomes heavy and the usability is reduced. Also, if a large amount of wax is added to improve the bleeding-preventing effect, the lip cosmetic will be hardened, and if the amount of the powder is increased, the gloss will be reduced, and the usability will be impaired. Therefore, development of a lip cosmetic having excellent usability and adhesiveness and having an effect of preventing bleeding has been desired.
Here, the bleeding refers to the fact that the cosmetic gradually breaks down from the vertical wrinkles of the lip with time when the cosmetic is applied on the lip.

[0004]

Under these circumstances, the present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, by blending a specific component, the usability and adhesion are excellent, and furthermore, there is no conventional method. The present inventors have found that a lip cosmetic having an excellent bleeding-preventing effect can be obtained, and have completed the present invention. That is, the present invention is characterized by containing the following components: (A) an oil-soluble N-long-chain acyl acidic amino acid mono- or diester (B) ethylene-propylene copolymer (C) abietic acid ester and / or diglyceryl oligoester. Lip cosmetics.
