Abstract

A treatment agent for animal fiber protection which comprises an aqueous solution containing divalent metal ions or a divalent metal salt. The treatment agent prevents hair and animal fiber damage associated with permanent wave treatments, bleaching treatments, etc.

Claims

1. A treatment agent for animal fiber protection comprising an aqueous solution containing divalent metal ions or a divalent metal salt.

2. The treatment agent according to claim 1, wherein the divalent metal is calcium.

3. The treatment agent according to claim 1, wherein the divalent metal salt is a chelate-like substance selected from the group of calcium hydroxide, magnesium hydroxide, hydroxy acid salt, and ethylene diamine tetraacetate salt.

4. An animal fiber treatment method, wherein, in a process of conducting oxidation treatment for animal fibers consisting of keratin, the treatment agent according to claim 1 is brought into contact with the animal fibers before and/or after said treatment.

5. The treatment method according to claim 4, wherein, in a process, of conducting permanent wave treatment for human hair, the treatment agent is brought into contact with the human hair before and/or after said wave treatment.

6. The treatment method according to claim 4, wherein, in a process of conducting coloring treatment for human hair, the treatment agent is brought into contact with

7. The treatment method according to claim 4, wherein, in a process of conducting bleaching treatment of sheep'"'"'s wool, the treatment agent is brought into contact with the sheep'"'"'s wool before and/or after said bleaching treatment.

8. A method of treating hair that is subject to a process of varying a physical characteristic of the hair, comprising:

applying a reducing agent including thioglycolic acid to the hair;

applying a hair treatment agent that provides cystic acid to the hair; and

applying a hair stabilizing treatment containing one of calcium, magnesium and barium in sufficient quantity to react with the cystic acid from the hair treatment for protect the hair.

9. The method of claim 8 further including providing a chelating agent in the hair stabilizing treatment.

10. The method of claim 8 wherein the hair stabilizing treatment includes a metal compound selected from a group consisting of calcium hydroxide, magnesium hydroxide, calcium lactate, magnesium lactate, calcium gluconate, calcium citrate, calcium malate, calcium saccharate, and calcium chloride.

11. The method of claim 10 further including a chelating agent to assist dissolution of divalent metals selected from a group consisting of ethylene diamine tetraacetate, nitrilo triacetate, diethylene triamine pentaacetate, hydroxy ethyl ethylene diamine triacetate, triethylene triamine hexaacetate, 1,3-propane diamine tetraacetate, 1,3-diamino-2-hydropropane tetraacetate, hydroxy ethylimino diacetate, dihydroxy ethyl glycine, glycol ether diamine tetraacetate, and dicarboxy methyl glutamic acid.

12. The method of claim 8 wherein the calcium, magnesium and barium are organic acid salts selected from a group consisting of aliphatic hydroxy acid metal salts and aromatic hydroxy acid metal salts.

13. The method of claim 12 wherein the aliphatic hydroxy acid metal salts include lactic acid, gluconic acid, ascorbic acid, citric acid, malic acid, glycolic acid, oxypropionic acid, tartaric acid, and glucaric acid.

14. The method of claim 12 wherein the aromatic hydroxy acid metal salts include gallic acid and hydroxybenzoic acid.
