Surface-modified pigments and fillers for cosmetic applications were introduced to formulators in teh United States from Japan by Shoji Murata and Ryota Myoshi in 1981. These original materials, intended for use primarily in pressed powders, were treated with a combination of polymethyl hydrogensiloxane (methicone) and mineral oil, rendering them hydrophobic. Since 1981, the number of available surface treatments has greatly expanded, and their utility has been established in all types of color cosmetics.
