Problems solved by technology

[0005] In addition, in foundation (foundation), etc., in order to add color, it is necessary to mix iron oxide-based pigments, etc., but if you want to enrich titanium oxide in such a system, because the melt viscosity becomes high, there are Disadvantages such as poor dispersion of coloring materials (ie: color materials), and color spots (ie: color spots)

Abstract

Disclosed is an oil-based solid cosmetic preparation containing (a) 30-50% by mass of titanium oxide, (b) 5-30% by mass of an iron oxide-based pigment, and (c) 2-5% by mass of diglyceryl diisostearate.

Description

technical field [0001] The present invention relates to an oil-based solid cosmetic preparation. Background technique [0002] At present, in order to hide skin damages such as skin scars, thick application of cosmetics is generally used to cover scars and the like so as to make them less visible. [0003] However, in cosmetics generally used, since the degree of skin damage such as skin scars varies, there are still many cases that cannot be dealt with. Therefore, a cosmetic that can effectively hide skin damage is required. [0004] On the other hand, the titanium oxide powder used in the embodiment of the present invention is also used as a powder for cosmetics, and examples of formulations rich in the titanium oxide powder include Example 3, Examples 1 and 2 of Patent Document 2, however, are not examples that have a good effect on the repair of damaged skin parts. [0005] In addition, in foundation (foundation), etc., in order to add color, it is necessary to mix iro...
