Claims
- 1. A method of treating hair to cause the hair to maintain a desired configuration, said method comprising contacting the hair while in said desired configuration with an effective amount of an aqueous composition comprising the product formed by mixing in an aqueous medium at least one water-soluble quanidine salt in solution in said aqueous medium in an amount of greater than 0.25 molar in quanidine and an effective amount of at least one particulate, strong-base, quaternary ammonium, hydroxide-form ion-exchange resin, wherein said resin has an affinity for the anion of said quanidine salt which is at least equal to the affinity of the resin for the hydroxyl ion, and removing said composition from the hair after said composition has been in contact with the hair for an effective time.
- 2. Method of claim 1, wherein said ion-exchange resin is in finely divided form.
- 3. Method of claim 1, wherein said salt is selected from the group consisting of guanidine sulfate, guanidine hydrochloride, guanidine nitrate, guanidine tartrate, guanidine sulfite and guanidine oxolate.
- 4. Method of claim 1, wherein said guanidine salt and said ion-exchange resin are mixed together at a temperature of about 5.degree. to about 95.degree. C.
- 5. Method of claim 1, wherein said desired configuration is a straightened configuration, and the hair is in the straightened configuration at least during a portion of the time it is contacted by said aqueous composition.
- 6. Method of claim 1, wherein said guanidine salt is selected from the group consisting of guanidine sulfate, carbonate, hydrochloride, nitrate, sulfite, phosphate, fluoride, oxalate, thioglycolate and alginate and guanidine carboxylic acid salts of alkane and alkene carboxylic acids having from 2 to about 20 carbon atoms.
- 7. Method of claim 2, wherein the resin has a particle size of less than 400 mesh.
- 8. A system for treating hair to cause the hair to maintain a desired configuration, said system comprising an aqueous medium containing a hair treating-effective amount of guanidine hydroxide and at least one particulate, strong-base, quaternary ammonium ion-exchange resin having bound thereto at least a stoichiometric amount, based on the amount of said guanidine hydroxide, of an anion which when combined with the guanidine ion produces a water-soluble salt, said resin having an affinity for said anion at least as great as for the hydroxyl ion.
- 9. System of claim 8, wherein said system is suitable for straightening hair to cause the hair to maintain a straightened configuration.
- 10. System of claim 8, wherein said resin has a particle size of less than 400 mesh.
- 11. System of claim 8, wherein said anion is selected from the group consisting of sulfate, nitrate, tartrate, oxolate, hydrochloride and sulfite anions.
- 12. A method of treating hair to cause the hair to maintain a desired configuration, said method comprising contacting the hair while in said desired configuration with an effective amount of an aqueous composition comprising the product formed by mixing in an aqueous medium at least one water-soluble guanidine salt in solution in said aqueous medium in an amount of greater than 0.25 molar in guanidine and an effective amount of at least one particulate, strongbase, quaternary ammonium, hydroxide-form ion-exchange resin, wherein said resin has a salt splitting capacity of at least about 3.0 meq/g. and an affinity for the anion of said guanidine salt which is at least equal to the affinity of the resin for the hydroxyl ion, and removing said composition from the hair after said composition has been in contact with the hair for an effective time.
- 13. Method of claim 12, wherein said salt splitting capacity is at least about 3.5 meq/g.
- 14. Method of claim 13, wherein at least 40 grams of resin are used to treat each adult head of hair.
- 15. Method of claim 14, wherein at least 50 grams of said resin are used for each adult head of hair.
