Abstract:
A method of treating hair comprising:i) wetting the hair; ii) applying an aqueous hair care composition comprising water-insoluble particles having a layered structure which is a clay in which organic functional groups have been introduced during formation of the clay, the organic functional groups being covalently bonded to silicone in the clay, and wherein the particles have the formula: Mg6Si8R8O16(OH)4, â€ƒwherein R is an organic functional group selected from C1-C20 alkyl, alkenyl, alkynyl, aralkyl and aryl groups, optionally substituted with one or more of the same or different groups selected from halo, ORâ€², OCOR1, NR2R3, N+R4R5R6, COX, NCO, NO2, SO2R7, SO3H, H2PO4, PO(ORâ€²)2 and heterocycloalkyl, wherein X is selected from halo, OR8, OCOR9, OH, H and R10 and Râ€², R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are independently selected from C1 to C6 alkyl, C2 to C6 alkenyl and hydrogen, and when organic functional groups comprise CO2H, SO3H, OH or H2PO4, they may be in salt form;iii) rinsing the hair.
