Hydrophilic foam pad for hair styling
First Claim
1. A hair conditioning and styling pad consisting essentially of a resilient, open-celled, hydrophilic polyurethane foam matrix, wherein bound to said matrix is an aqueous phase incorporating about 70-90% water, about 5-25% of a polymeric organic film-forming hair conditioning agent and about 0.1-10% of a nonionic surfactant, wherein said aqueous phase does not include a significant amount of water-immiscible organic solvent.

Abstract
A hair conditioning and styling pad is provided which comprises a shaped body of a resilient, open-celled, hydrophilic polyurethane foam matrix integrally incorporating an aqueous phase incorporating about 70-90% water, about 5-25% of a hair conditioning agent, and a nonionic surfactant. The pad is preferably affixed to the tines of a styling brush or comb to yield a composite brush or comb which is effective to condition and style hair.

20. A hair styling and conditioning pad formed by a process comprising:
-
(a) forming an aqueous reactant phase comprising a dispersion in about 70-90% water of about 5-25% of a polymeric organic film-forming hair conditioning agent and about 0.1-10% of a nonionic surfactant comprising a polyoxalkylene block copolymer of a mixture of a polyoxyalkoxylated lanolin and a polyoxyalkoxylated fatty alcohol, wherein said aqueous reactant phase does not include a significant amount of water-immiscible organic solvent; and (b) mixing said aqueous reactant phase with a water-foamable prepolymer resin which contains at least 2 free isocyanate groups per resin molecule in a weight ratio of aqueous reactant phase to prepolymer resin of about 3.0-1.0;
1, thereby forming said resin into a hydrophilic, open-celled, highly reticulated polyurethane foam pad. - View Dependent Claims (21, 22, 23, 24, 25, 26)
