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. In a further modification of the invention, color-modified aqueous phases will further comprise about 5-25% of a temporary hair coloring agent, and the percentage of water in the color-modified aqueous phase will be about 60-80%.

Claims

1. A hair coloring, 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 60-80% water, about 5-25% of a temporary hair coloring agent, about 5-25% of a polymeric organic film-forming hair conditioning agent, and about 0.1-10% of a nonionic surfactant.

2. The pad of claim 1 wherein the nonionic surfactant comprises a water-soluble polyoxyalkylene block copolymer.

3. The pad of claim 2 wherein the copolymer comprises a polyoxypropylene ether having a molecular weight of about 1750-2250 and a polyoxyethylene content which is about 40-60% of the copolymer by weight.

4. The pad of claim 1 wherein the aqueous phase further comprises about 0.5-2.5% of an inorganic alkali metal or alkaline earth metal salt.

5. The pad of claim 1 wherein the hair conditioning agent comprises a cationic organic polymer.

6. The pad of claim 5 wherein the hair conditioning agent comprises collagen or a collagen derivative.

7. The pad of claim 5 wherein the hair conditioning agent comprises a cationic cellulosic polymer.

8. The pad of claim 5 wherein the hair conditioning agent comprises a vinylpyrrolidone-based polymer or copolymer.

9. The pad of claim 1 which further comprises a minor but effective amount of fragrance.

10. A hair coloring, 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 65-75% water, about 10-20% of a temporary hair coloring agent, about 10-20% of a polymeric organic film-forming hair conditioning agent, about 0.25-5% of a nonionic surfactant, and an amount of an inorganic salt effective to substantially enhance the release of the aqueous phase from the foam matrix when the pad is pressed against the hair.

11. The pad of claim 10 wherein the cells of said pad substantially vary in diameter.

12. The pad of claim 10 wherein a substantial number of said cells are about 1.0-5.0 mm in diameter.

13. The pad of claim 10 wherein the aqueous phase further comprises about 1-20% of a particulate soft mineral absorbent which is silane-coupled to the foam matrix.

14. The pad of claim 10 wherein the aqueous phase further comprises a minor but effective amount of a topically active insecticide or a minor but effective amount of an antidandruff agent.

15. The pad of claim 10 wherein the aqueous phase further comprises a minor but effective amount of fragrance.

16. The pad of claim 10 wherein the hair conditioning agent comprises hydrolyzed animal protein or a derivative thereof.

17. The pad of claim 10 wherein the hair conditioning agent comprises a cationic polymer.

18. The pad of claim 17 wherein the hair conditioning agent comprises a cationic cellulosic polymer.
