Abstract

A hair cleaning and conditioning 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 1-20% of a water-immiscible organic solvent, about 0.05-1.5% of a hair conditioning agent and a mixture of surfactants comprising a nonionic surfactant, a cationic surfactant and, optionally, an amphoteric surfactant. The pad is preferably affixed to the tines of a styling brush to yield a composite brush which is effective to clean and condition dry hair.

Claims

1. A hair cleaning and conditioning pad comprising a , resilient, open-celled, hydrophilic polyurethane foam matrix, wherein bound to said matrix is an aqueous phase incorporating about 70-90% water, about 1-20% of a water-immiscible organic solvent, about 0.05-1.5% of a polymeric organic film-forming hair conditioner and about 0.5-15% of a mixture of an anionic surfactant and a nonionic surfactant.

2. The pad of claim 1 wherein the aqueous phase further comprises about 0.25-5% of an amphoteric betaine surfactant.

3. The pad of claim 1 wherein the ratio of anionic surfactant to nonionic surfactant is about 7.5-0.25:

1.

4. The remover pad of claim 1 wherein the anionic surfactant comprises a sulfated fatty alcohol amine salt and the nonionic surfactant comprises a polyoxyalkylene block copolymer.

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

6. The pad of claim 1 wherein the hair conditioner comprises a cationic organic polymer.

7. The pad of claim 6 wherein the hair conditioner comprises collagen or a collagen derivative.

8. The pad of claim 6 wherein the hair conditioner comprises a cationic cellulosic polymer.

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

10. A hair cleaning and conditioning pad comprising a resilient, open-celled, hydrophilic polyurethane foam matrix, wherein bound in or on said matrix, is an aqueous phase incorporating about 75-87.5% water, about 0.025-7.5% of a polymeric organic film-forming, hair conditioner, about 5-15% of a water-immiscible organic solvent, about 0.1-5% of a nonionic surfactant, about 0.5-10% of an anionic surfactant, and an amount of an inorganic salt effective to substantially enhance the release of the aqueous phase from the foam matrix to the hair when the pad is pressed against the hair.

11. The pad of claim 10 wherein the water-immiscible organic solvent comprises an isoparaffin oil.

12. 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.

13. The pad of claim 10 wherein the aqueous phase further comprises minor but effective amounts of an antidandruff agent.

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

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

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

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

18. The pad of claim 10 wherein the hair conditioner comprises a cationic cellulosic polymer.

19. An assembly for treatment of hair or the like;

said assembly comprising;

(a) a base member;

(b) a hair cleaning pad member mounted on said base member;

said pad member comprising a resilient, open-celled, hydrophilic polyurethane foam matrix, wherein bound to said matrix is an aqueous phase incorporating about 70-90% water, about 1-20% of a water-immiscible organic solvent, about 0.05-1.5% of a polymeric organic film-forming hair conditioner and about 0.5-1.5% of a mixture of an anionic surfactant and a nonionic surfactant.

20. An assembly according to claim 19 including tine means upon which said hair cleaning pad member is impaled.

21. An assembly according to claim 19 wherein:

(a) said base member comprises a brush having a plurality of tines projecting outwardly therefrom; and

,

(b) said pad member is impaled upon said plurality of tines.

22. A kit for providing cleaning and conditioning of hair;

said kit including;

(a) at least one base member;

(b) at least one pad member mountable on said base member;

said at least one pad member comprising a resilient, open-celled, hydrophilic polyurethane foam matrix, wherein bound to said matrix is an aqueous phase incorporating about 70-90% water, about 1-20% of a water-immiscible organic solvent, about 0.05-1.5% of a polymeric organic film-forming hair conditioner and about 0.5-1.5% of a mixture of an anionic surfactant and a nonionic surfactant.

23. A kit according to claim 22 wherein:

(a) said at least one member comprises a brush having a plurality of tines projecting outwardly therefrom; and

,

(b) said at least one pad member is operably impalable on said plurality of tines.

24. A method of cleaning and conditioning hair;

said method comprising;

(a) providing an assembly comprising a base member with a pad member mounted hereon;

said pad member comprising a resilient, open-celled, hydrophilic polyurethane foam matrix, wherein bound to said matrix is an aqueous phase incorporating about 70-90% water, about 1-20% of a water-immissible organic solvent, about 0.05-1.5% of a polymeric organic film-forming hair conditioner and about 0.5-1.5% of a mixture of an anionic surfactant and a nonionic surfactant; and

,

(b) manipulating said base member to bring said pad member into contact with hair to be cleaned and conditioned.

25. The method according to claim 24 including the steps of:

(a) providing tine means projecting through said pad member; and

,

(b) brushing said tine means through the hair to be cleaned and conditioned.

26. The method according to claim 24 wherein:
