Abstract

The instant disclosure generally relates to a multicomponent composition for coloring mammalian or synthetic substrate material and textiles, the composition comprising a first and second components and a third component. The first and second components comprise first and second silicone polymers respectively. Any one or more of the first, second and third components may also comprise pigment microparticles. The first, second and third compounds meld together on substrate material and textiles and especially on hair to form a highly remanent colored coating. The multicomponent composition formed and set in situ as a solid linked coating has a substantially permanent pigment lastingness and minimally alters the substrate material and textiles.
