Abstract
Abstract @ This invention relates to a new permanent wave neutralizer and to methods of permanently waving hair. More particularly, the neutralizer comprises an oxidizing agent in combination with a polyvalent metal salt selected from water-dispersible, non-toxic salts of aluminum, zirconium, aluminum zirconium coordination complexes and mixtures thereof.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
75 words
A permanent wave neutralizer and oxidizing composition including: (a) about 0.01 to about 10 weight percent of a water-dispersible, non-toxic polyvalent metal salt of a strong mineral acid having a cation selected from the group consisting of aluminum (III), zirconium (IV), aluminum zirconium coordination complexes and mixtures thereof; (b) about 0.5 to about 15 weight percent of an oxidizing agent; (c) water; wherein the composition has a pH value of about 2 to about 7.
Claim 2
Dependent Claim
75 words
A permanent wave neutralizer and oxidizing composition including: (a) about 0.01 to about 10 weight percent of a water-dispersible, non-toxic polyvalent metal salt of a strong mineral acid having a cation selected from the group consisting of aluminum (III), zirconium (IV), aluminum zirconium coordination complexes and mixtures thereof; (b) about 0.5 to about 15 weight percent of an oxidizing agent; (c) water; wherein the composition has a pH value of about 2 to about 7.

Claim 8
Dependent Claim
8 words
A permanent wave neutralizer and oxidizing composition including
Claim 9
Dependent Claim
8 words
A permanent wave neutralizer and oxidizing composition including
Claim 10
Dependent Claim
68 words
(a) about 0.05 to about 1 weight percent of a water-dispersible non-toxic polyvalent metal salt of a strong mineral acid having a cation selected from the group consisting of aluminum (III), zirconium (IV), aluminum zirconium coordination complexes and mixtures thereof; (b) about 0.5 to about 15 weight percent of an oxidizing agent; and (c) water; wherein the composition has a pH value of about 2 to about 7.
Claim 11
Dependent Claim
68 words
(a) about 0.05 to about 1 weight percent of a water-dispersible non-toxic polyvalent metal salt of a strong mineral acid having a cation selected from the group consisting of aluminum (III), zirconium (IV), aluminum zirconium coordination complexes and mixtures thereof; (b) about 0.5 to about 15 weight percent of an oxidizing agent; and (c) water; wherein the composition has a pH value of about 2 to about 7.
Claim 12
Dependent Claim
36 words

Claim 13
Dependent Claim
37 words
The composition of claim 7 wherein the oxidizing agent is sodium bromate present at a concentration of about 5 to about 15 weight percent in a composition having a pH value of about 4 to about 7.
Claim 14
Dependent Claim
98 words
A method of treating hair for purposes of permanently waving said hair comprising the steps of contacting the hair with an effective amount of hair keratin disulfide-bond breaking agent selected from the group consisting of thiol and sulfite reducing agents; maintaining said contact for a period of time sufficient to form partially reduced hair keratin; removing the keratin reducing agent from the hair; contacting the partially reduced hair with the neutralizer composition of claim 1; maintaining said contact for a period of time sufficient to rebuild the broken keratin disulfide bonds; and removing the neutralizer from the hair.
Claim 15
Dependent Claim
97 words
A method of treating hair for purposes of permanently,waving said hair comprising the steps of contacting the hair with an effective amount of hair keratin disulfide-bond breaking agent selected from the group consisting of thiol and sulfite reducing agents; maintaining said contact for a period of time sufficient to form partially reduced hair keratin; removing the keratin reducing agent from the hair; contacting the partially reduced hair with the neutralizer composition of claim 7; maintaining said contact for a period of time sufficient to rebuild the broken keratin disulfide bonds; and removing the neutralizer from the hair.
