ABSTRACT:
Perfluoro compounds such as C.sub.12 F.sub.20 ; C.sub.12 F.sub.27 N; C.sub.12 F.sub.26 O; C.sub.8 F.sub.17 Br; and C.sub.14 F.sub.24 are rendered dispersible colloidally in water or other polar media without the aid of an emulsifying agent by providing a matrix formed by subjecting a feedstock containing perfluoro compounds and carrier materials to conditions which alter the physical and/or chemical structure of the carrier material. The matrix suspends the perfluoro compounds for delivery to a dispersible medium. Thus, a family of new colloidal perfluoro compounds is produced. Methods of producing readily dispersible perfluoro compounds in the absence of emulsifying agents and cosmetics including the same are also disclosed.
