Abstract
A low volatile organic compound hair cosmetic composition containing a water insoluble, hydrolytically stable polypropylene oxide-modified polydimethylsiloxane block copolymer exhibits excellent spray characteristics and minimized contact foaming while providing high curl retention, fast drying time and low initial curl droop. The composition contains 0.001 to 0.9% of a polypropylene oxide-modified polydimethylsiloxane block copolymer which contains essentially no ethylene oxide, 1 to 15% of a film-forming resin, up to 70% of a solvent, 10 to 60% of a propellant, and water.
Claims17
A hair cosmetic composition providing improved spray aesthetics and foam dissipation comprising:
- from about 0.001 to about 0.9% by weight of a polymer, said polymer being an Si--C linked polypropylene oxide-modified polydimethylsiloxane block copolymer of the alkoxy-end blocked type or the alkyl-pendant type which contains essentially no ethylene oxide;
- from about 1 to about 15% by weight of at least one film-forming resin;
- up to about 70% by weight of a solvent;
- from about 10 to about 60% by weight of a propellant;
- and
- water as the balance;
- wherein the composition contains essentially no starch syrup and no more than about 80% of one or more volatile organic compounds.
A hair cosmetic composition providing improved spray aesthetics and foam dissipation consisting essentially of:
- from about 0.001 to about 0.9% by weight of a polymer, said polymer being an Si--C linked polypropylene oxide-modified polydimethylsiloxane block copolymer of the alkoxy-end blocked type or the alkyl-pendant type which contains essentially no ethylene oxide;
- from about 1 to about 15% by weight of at least one film-forming resin;
- up to about 70% by weight of a solvent;
- from about 10 to about 60% by weight of a propellant;
- and
- water as the balance,
- wherein the composition contains no more than about 80% of one or more volatile organic compounds.
A method for improving the spray aesthetics and foam dissipation of a hair cosmetic composition which contains no more than about 80% of one or more volatile organic compounds comprising from about 1 to about 15% by weight of a film-forming resin;
- up to about 70% by weight of a solvent;
- from about 10 to about 60% by weight of a propellant;
- and water as the balance, the method comprising formulating the composition with from about 0.001 to about 0.9% by weight of a polymer, said polymer being an Si--C linked polypropylene oxide-modified polydimethylsiloxane block copolymer of the alkoxy-end blocked type or the alkyl-pendant type which contains essentially no ethylene oxide.
