Description

  The present invention relates to a water-in-oil solid emulsified cosmetic.

  In recent years, many water-in-oil solid emulsified cosmetics have been distributed on the market, and variations in their appearance and feel are various. This type of cosmetic is in the form of being solidified and filled in a container so that it does not have fluidity even at room temperature, considering the convenience and usability of carrying. Moreover, since it is an emulsification type containing water unlike oily type cosmetics, a refreshing feeling, freshness, etc. can be given at the time of use.

The solidification for maintaining the cosmetic in a certain form is generally performed by solid oil such as wax, and various amounts and types of solid oil have been studied for the purpose of appropriate hardness and good usability. (Patent Documents 1 and 2).
On the other hand, in general, a hydrophobized powder is blended in an oil phase for the purpose of improving the feeling of use such as good elongation during use (Patent Document 3).

JP 2009-215232 A JP 2006-282632 A Japanese Patent Laid-Open No. 2-88511

However, when the hydrophobized powder is blended in the oil phase, the pigment dispersibility in the oil phase becomes too high, and there is a problem that the hardness near the melting temperature of the wax is remarkably lowered. This affects the stability when the product is transported or displayed at the store.
And, when trying to suppress the decrease in hardness in the vicinity of the melting temperature of the wax by increasing the wax content, the formulation becomes too hard and it is difficult to remove cosmetics from the container or the like when used. There arises a problem that the coating comfort becomes worse.
Therefore, the present invention relates to a water-in-oil solid emulsified cosmetic having a reduced feeling of hardness near the melting temperature of the wax and having an excellent feeling of use.

  The present inventor uses an organic titanate-treated powder in combination with polyether-modified silicone, wax, and a branched fatty acid ester that is liquid at 25 ° C., thereby suppressing a decrease in hardness in the vicinity of the melting temperature of the wax. It was found that a water-in-oil solid emulsified cosmetic having a feeling was obtained, and the present invention was completed.

That is, the present invention provides a water-in-oil type solid emulsified cosmetic containing the following components (A) to (D).
(A) Organic titanate-treated powder (B) Polyether-modified silicone (C) Wax (D) Branched fatty acid ester liquid at 25 ° C
