Abstract
Abstract Mercaptyl-containing quaternary nitrogen compounds, which may contain additional functional moieties such as dye, polysiloxane, or polyoxyalkylenes groups, are useful in the treatment of hair, used in hair-treating compositions, to impart properties such as conditioning, shape, color, sheen, and manageability.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A hair-treating composition comprising an effective hair-treating amount of a mercapto-containing quaternary nitrogen compound of the formula: ##STR4## a is 1; m and n are each independently about 1 to about 20; R 1 is alkyl; R 2 is alkyl; R 3 is a silicon containing substituent of the formula --(CH.sub.2).sub.p --OSi(R.sub.4)(R.sub.5)--[OSi(R.sub.4)(R.sub.5)].sub.b --R.sub.5 wherein: b is about 1 to about 25; p is about 1 to about 14; and R 4 and R 5 are each independently lower alkyl, with R 6 , R 7 , and R 8 each being independently lower alkyl; and X - is a nontoxic anion.
Claim 2
Dependent Claim
101 words
A hair-treating composition comprising an effective hair-treating amount of a mercapto-containing quaternary nitrogen compound of the formula: ##STR4## a is 1; m and n are each independently about 1 to about 20; R 1 is alkyl; R 2 is alkyl; R 3 is a silicon containing substituent of the formula --(CH.sub.2).sub.p --OSi(R.sub.4)(R.sub.5)--[OSi(R.sub.4)(R.sub.5)].sub.b --R.sub.5 wherein: b is about 1 to about 25; p is about 1 to about 14; and R 4 and R 5 are each independently lower alkyl, with R 6 , R 7 , and R 8 each being independently lower alkyl; and X - is a nontoxic anion.
Claim 3
Dependent Claim
26 words
A composition according to claim 1, including an effective catalytic amount of a mercaptyl-disulfide interchange catalyst which is thioredoxin, a thioredoxin-derived, or a thioredoxin-like dithiol peptide.
Claim 4
Dependent Claim
120 words
An aqueous composition useful for permanently conditioning and shaping hair comprising a compound of the formula: ##STR5## wherein: a is 1; m and n are each independently about 1 to about 20; R 1 is alkyl; R 2 is alkyl; R 3 is a silicon-containing substituent of the formula: --(CH.sub.2).sub.p --OSi(R.sub.4)(R.sub.5)--[OSi(R.sub.4)(R.sub.5)].sub.b --R.sub.5 wherein: b is about 1 to about 25; p is about 1 to about 14; and R 4 and R 5 are each independently lower alkyl, with R 6 , R 7 , and R 8 each being independently lower alkyl; and X - is a nontoxic anion; and an effective catalytic amount of a mercaptyl-disulfide interchange catalyst which is thioredoxin, a thioredoxin-derived or a thioredoxin-like dithiol peptide.
Claim 5
Dependent Claim

Claim 6
Independent Claim
101 words
A method for treating keratinous fiber to impart desired properties thereto comprising contacting keratinous fiber containing disulfide bonds with an aqueous composition containing a mercaptyl-containing quaternary nitrogen compound of the formula: ##STR6## wherein a is 1; m and n are each independently about 1 to about 20; R 1 is alkyl; R 2 is alkyl; R 3 is a silicone containing substituent of the formula --(CH.sub.2).sub.p --OSi(R.sub.4)(R.sub.5)--[OSi(R.sub.4)(R.sub.5)].sub.b --R.sub.5 wherein: b is about 1 to about 25; p is about 1 to about 14; and R 4 and R 5 each being independently lower alkyl; and X - is a nontoxic anion.
