Patent ID: 11504314

Abstract:
A multi-chrome cosmetic hair composition is disclosed. The composition includes a base formula suitable for hair and an interference pigment providing a colored background exhibiting interference colors that are observable at different angles of observation. The formula is sufficient to enable a homogenous suspension of the interference pigment. The formula includes a propellant, denatured alcohol, neutralized octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer 4, a neutralizing agent sufficient to neutralize the octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer 4 to a range of 80% to 100%, and a plasticizer. The interference pigment includes an opaque-type interference pigment consisting of particles ranging from 5 microns to 60 microns in size to fill in gaps on hair shaft surfaces and create a smooth, chrome-like effect on the hair. The interference pigment includes an inorganic layer that specularly reflects incident light and semi-transparent inorganic layers that refract the reflected light such that the interference colors are observable.
