Makeup compositions in cake form including fibroin-coated and oily material-coated pigments
First Claim
1. A cosmetic makeup composition consisting essentially of a homogenous mixture of from 10 to 90% by weight of finely divided, fibroin-coated, pigment particles and finely divided, oily material-coated, pigment particles, said fibroin-coated, pigment particles consisting essentially of first carrier pigment particles each substantially uniformly coated with a film of regenerated fibroin wherein the amount of said regenerated fibroin is from 2 to 100% by weight based on the weight of said first carrier pigment particles, at least 50% by weight of said regenerated fibroin consisting of hot-water-insoluble fibroin having the β
- -configuration, and said oily material-coated, pigment particles consisting essentially of second carrier pigment particles the surfaces of which are substantially uniformly coated with substantially water-insoluble, oily material suitable for use in cosmetics, the amount of said oily material being from 10 to 15% by weight based on the weight of said second carrier pigment particles, said composition being in the form of a compressed cake.

Abstract
A makeup composition is disclosed which consists essentially of a homogeneous mixture of a fibroin-coated pigment comprising a carrier pigment in the form of finely divided particles whose surfaces are substantially coated with a film of regenerated fibroin and an oily material-coated pigment comprising a carrier pigment in the form of finely divided particles whose surfaces are substantially coated with an oily material and which is in the form of powder (i.e., loose powder) or a cake (i.e., pressed powder). This makeup composition in powder or cake form has excellent properties such as adhesion to the skin, moisture retention, durability of the makeup, fragrance retention, stability and the like, causes no irritation to the skin, and can give an agreeable feeling (i.e., a moist and silkily smooth feeling) and a natural silk-like gloss to the skin. In particular, the makeup composition in cake form can be smoothly applied to the skin during all seasons by using a wet applicator (e.g., a wet puff) and/or a dry applicator (e.g., a dry puff). It is so stable that no agglomeration or caking of its particles results.
