Description

Lip cosmetic

The present invention relates to a lip cosmetic.

The lip cosmetic has a lipstick, a lip cream, a gloss, and the like. As a shape thereof, a solid injection type in which a rod-shaped type (solid type) is directly filled in a metalware or a resin vessel is used. A liquid type (non-solid) filled in a tube or a bottle.

Among these, a solid lipstick such as a rod has a good color, but is inferior in gloss. In addition, although the non-solid state represented by lip gloss is very high in glossiness, it is not sufficient in terms of coloration, stickiness, hydration, and hydration.

Therefore, the industry has studied a lip cosmetic which has good gloss and good color rendering, good feeling of use, and high hydration performance.

For example, a non-solid lip cosmetic containing a high-viscosity oil component and a specific semi-solid oil component in a specific ratio has been proposed (Patent Document 1). The non-solid lip cosmetic has no stickiness, is excellent in gloss and transparency when applied, but is inferior in coloring or hydration and hydration.

Further, a paste-like lip cosmetic containing a specific wax, a dextrin fatty acid ester, an oil-soluble resin, and a plate-like powder has been studied (Patent Document 2), or two kinds of hydrocarbons, hydrating oils, and pastes having different melting points have been studied. An oily cosmetic of a fine fatty acid ester (Patent Document 3) or the like. However, although these cosmetics have a good feeling of use, there is a problem in that the hydration degree or the hydration degree is lowered due to the use of a gelling agent.
