JP6285192B2 - Gel lip cosmetic - Google Patents

Description

  The present invention relates to a gel-like lip cosmetic, and more particularly to a gel-like lip cosmetic that has a smooth spread and gloss, is excellent in makeup blurring, and has good stability.

In the recent market for lip cosmetics, there is a demand for products that are easy to use and have good makeup, and various studies have been made to produce them.
For example, the oil gel cosmetic technology (Patent Document 1) containing polybutene and dextrin fatty acid ester, which is excellent in gloss and stability, and oxyacid ester and heavy liquid isoparaffin with light usability without impairing gloss The technique (patent document 2) etc. of the composition for lipsticks containing methylphenyl polysiloxane have been examined.

JP 2002-003340 A JP 2001-114648 A

  However, the oil gel cosmetic containing polybutene and dextrin fatty acid ester is excellent in gloss, but has a heavy touch when used and it is difficult to obtain a smooth spread. In addition, the technology of lipstick compositions containing oxyesters, heavy liquid isoparaffins, and methylphenylpolysiloxane provides good (light) usability without impairing gloss, but the composition is liquid or semi-solid. In the case of the shape, the stability may be lacking. For this reason, it has been desired to develop a gel-like lip cosmetic that has a smooth spread and gloss, is not smeared with makeup, and has good stability.

  As a result of intensive studies, the inventors of the present invention obtained a gel stability by combining an oil gelling agent having a sugar skeleton, a methyl phenyl polysiloxane that is glossy and light to the touch, and dimethicodiethylbenzalmalonate. In addition, thixotropy is imparted to cosmetics, and smooth expansion spreads, but by making a film with a thick film, gel-like lip cosmetics with no makeup blur and excellent gloss feel The inventors have found that the present invention can be obtained and have completed the present invention.

That is, the present invention provides the following components (a) (b) and (c);
(A) Oil gelling agent having a sugar skeleton (b) Methylphenylpolysiloxane (c) Gel-like lip cosmetic containing dimethicodiethylbenzalmalonate.
