Summary: | A cosmetic ingredient for cosmetic products has a polymer structure which includes an emollient or film-forming cosmetic polymer which is transparent to light. An organic chromophore molecule is inserted and chemically linked into the polymer, which can be a fixed color molecule or a photochromic molecule capable of rapidly switching from one color to another. The colored or photochromic molecule is inserted and chemically linked by transesterification into a cosmetic oil provided with functionalities which are suitable for the chemical anchoring of the molecule and chemically linked to said oil. The cosmetic oil may be a silicone macrodiol functionalized with a photochromic derivative designed so as to ensure the transition between a colorless state and a colored state following irradiation with ultraviolet light. |
