Abstract
Abstract An oil-in-water-in-silicone fluid (o/w/s) emulsion composition comprising (a) a silicone fluid continuous phase, (b) an aqueous discontinuous phase comprising an oil-in-water (o/w) emulsion, and (c) an effective dispersing amount of dimethicone copolyol for dispersing (b) in (a).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
56 words
An oil-in-water-in-silicone fluid emulsion composition comprising (a) a silicone fluid continuous phase consisting essentially of at least one liquid organopolysiloxane (b) an aqueous discontinuous phase comprising an oil-in-water emulsion of a cosmetically acceptable oily liquid non-particulate phase dispersed in an aqueous phase, and (c) an effective dispersing amount of dimethicone copolyol for dispersing (b) in (a).
Claim 2
Dependent Claim
56 words
An oil-in-water-in-silicone fluid emulsion composition comprising (a) a silicone fluid continuous phase consisting essentially of at least one liquid organopolysiloxane (b) an aqueous discontinuous phase comprising an oil-in-water emulsion of a cosmetically acceptable oily liquid non-particulate phase dispersed in an aqueous phase, and (c) an effective dispersing amount of dimethicone copolyol for dispersing (b) in (a).
Claim 3
Dependent Claim
24 words
The composition of Claim 1 wherein said liquid organopolysiloxane is a volatile organopolysiloxane selected from the group consisting of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane and hexamethyldisiloxane.
Claim 4
Dependent Claim
47 words
The composition of Claim 1 wherein said liquid organopolysiloxane is a non-volatile organopolysiloxane selected from the group consisting of dimethicone copolyol, dimethylpolysiloxane, diethylpolysiloxane, mixed C₁-C₃ alkyl polysiloxane, phenyl dimethicone and a high molecular weight dimethicone having an average molecular weight of from about 200,000 to about 1,000,000.
Claim 5
Dependent Claim
39 words
The composition of Claim 1 wherein said silicone fluid continuous phase consists essentially of one or more volatile organopolysiloxanes in mixture with one or more non-volatiles organopolysiloxanes in a respective weight ratio of from about 5:1 to about 25:1.
Claim 6
Dependent Claim
11 words
The composition of Claim 4 wherein said volatile organopolysiloxane is cyclomethicone.
Claim 7
Dependent Claim
37 words
The composition of Claim 1 having from about 15 to about 90 weight percent of (a), from about 30 to about 80 weight percent of (b), and from about 0.5 to about 5 weight percent of (c).
Claim 8
Dependent Claim
28 words
The composition of Claim 1 wherein the oily liquid phase of (b) comprises heavy mineral oil, cholesterol and cetyl palmitate in a respective weight ratio of about 10:5:1.
