Cosmetic makeup compositions comprising water-in-oil emulsions containing pigment

Claim 1

A cosmetic make-up composition which is a water-in-oil emulsion comprising a) an oil phase which comprises i) About 2 to 50% by weight of the oil phase of a coated pigment consisting essentially of finely divided particles of pigment whose surfaces are chemically bonded to, and physically completely coated by, polysiloxane which coating renders the particles hydrophobic, and ii) up to about 97% by weight of the oil phase of a silicone component selected from the group consisting of dimethyl polysiloxane having the formula (CH 3 ) 3 SiO(Si(CH 3 ) 2 O) d --Si(CH 3 ) 3 wherein the degree of polymerization d is effective to give the fluid a viscosity of 0.65 to one million centistokes at 25° C.; cyclomethicone having a degree of polymerizaton of 3 to 6; organopolysilioxane having the formula: X(CH.sub.3).sub.2 SiO--Y--Si(CH.sub.3).sub.2 X wherein X is alkyl or alkoxy having 1 to 30 carbon atoms and Y is a chain of 1 to 100 repeating (Si--O) units containing 1 to 100 units of the formula (--Si(R 1 )(R 2 )O--) and 0 to 100 units of the formula (Si(R 3 )(R 4 )O) wherein each of R 1 , R 2 , R 3 and R 4 can be alkyl containing 2 to 30 carbon atoms, phenyl, or phenyl connected to the Si atom by a vinyl group or an alkylene bridge 1 to 3 carbon atoms long; wherein each R 1 and R 3 can also be --CH 3 , and each R 1 and R 2 can also be trimethylsiloxy; and mixtures thereof; b) 15 to 60% by weight of the total composition of an aqueous phase; c) a surfactant which is a polydiorganosiloxane-polyoxyalkylene copolymer containing at least one polydiorganosiloxane segment consisting of R.sub.b SiO.sub.(4-b)/2 siloxane units wherein b has a value of from 0 to 3 inclusive, there being an average of approximately 2 R radicals per silicon in the copolymer, and R denotes a radical selected from the group consisting of methyl, ethyl, vinyl, phenyl and a divalent radical bonding a polyoxyalkylene segment to the polydiorganosiloxane segment, at least 95 percent of all R radicals being methyl; and containing at least one polyoxalkylene segment having an average molecular weight of less than 5000 and consisting of from 0 to 50 mol percent polyoxypropylene units and from 50 to 100 mol percent polyoxyethylene units, at least one terminal portion of said polyoxyalkylene segment being bonded to said polydiorganosiloxane segment, any terminal portion of said polyoxyalkylene segment not bonded to said polydiorganosiloxane segment being satisfied by a terminating radical; d) and further comprising a silicone-free surfactant having an HLB of 2-12; wherein said surfactants are present in a combined amount effective to form a stable emulsion of said water phase in said oil phase.
