Abstract
A cosmetic composition for making up keratin materials includes at least one polyelectrolyte, at least one surfactant having an HLB of at least about 6 at 25° C., and at least one dyestuff. A leave-on cosmetic composition for making up and/or nontherapeutic care of keratin fibers includes at least one polyelectrolyte, and at least one surfactant having an HLB of at least about 6 at 25° C. The polyelectrolytes may be branched and/or crosslinked, the compositions may include at least one of water and a water-soluble solvent, and the compositions may include an oily continuous phase.
Claims52
A cosmetic composition for making up keratin materials, the composition comprising:
- at least one polyelectrolyte;
- at least one surfactant having an HLB of at least about 6 at 25° C.;
- and
- at least one dyestuff;
- wherein:
- the polyelectrolyte is branched and/or crosslinked;
- the composition comprises at least one of water and a water-soluble solvent in an amount of less than about 50% by weight relative to a total weight of the composition;
- and
- the composition comprises an oily continuous phase.
A leave-on cosmetic composition for making up and/or nontherapeutic care of keratin fibers, the composition comprising:
- at least one polyelectrolyte;
- and
- at least one surfactant having an HLB of at least about 6 at 25° C.;
- wherein:
- the polyelectrolyte is branched and/or crosslinked;
- the composition comprises at least one of water and a water-soluble solvent in an amount of less than about 50% by weight relative to a total weight of the composition;
- and
- the composition comprises an oily continuous phase.
A leave-on cosmetic composition for making up and/or nontherapeutic care of keratin fibers, the composition comprising:
- at least one polyelectrolyte;
- and
- at least one surfactant having an HLB of at least about 6 at 25° C.;
- wherein:
- the polyelectrolyte comprises at least one member selected from the group consisting of an acrylamide/2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulphonic acid copolymer, a polyacrylate, a crosslinked starch glycolate in powdered form, a starch-based grafted copolymer, an ionizable polysaccharide derivative, a polyacrylic acid, a polyacrylic acid alkyl acrylate copolymer, a polyacrylamidomethylpropanesulphonic acid partially neutralized with aqueous anmmonia and highly crosslinked (AMPS), a crosslinked polyoxyethylenated AMPS/alkyl methacrylate copolymer, and a non-crosslinked polyoxyethylenated AMPS/alkyl methacrylate copolymer;
- and
- the composition comprises an oily continuous phase.
A method for preparing a cosmetic composition for making up keratin materials, the method comprising combining at least one polyelectrolyte and at least one surfactant having an HLB of at least about 6 at 25° C., wherein:
- the composition comprises an oily continuous phase;
- and
- the composition exhibits good water resistance and is easily removed
A method for preparing a leave-on cosmetic composition for making up and/or nontherapeutic care of keratin fibers, the method comprising combining at least one polyelectrolyte and at least one surfactant having an HLB of at least about 6 at 25° C., wherein:
- the composition comprises an oily continuous phase;
- and
- the composition exhibits good water resistance and is easily removed.
