## Abstract

Disclosed herein is a personal care conditioning and/or styling composition for keratin substrate comprising: (A) at least one conditioning and/or styling copolymer obtained from polymerizing: (i) about 0.1 wt. % to 99.9 wt. % of at least one cationic or pseudo-cationic monomer selected from the group consisting of acrylamidopropyl trimethylammonium chloride (APT AC) and/or diallyl dimethyl ammonium chloride (DADMAC); and (ii) about 0.1 wt. % to 99.9 wt. % of at least one monomer comprising at least one functionalized or unfunctionalized acryloyl moiety and at least one lactam moiety; (B) at least one cosmetically acceptable excipient; and (C) optionally, at least one effective amount of personal care active ingredient. Also disclose is a process for preparing such composition and method of use thereof.

## Claims

### Claim 1

A personal care conditioning and/or styling composition for a keratin substrate comprising:
A. at least one conditioning and/or styling copolymer obtained from polymerizing:
(i) about 0.1 wt. % to 99.9 wt. % of acrylamidopropyl trimethylammonium chloride (APTAC) or diallyl dimethyl ammonium chloride (DADMAC); and
(ii) about 0.1 wt. % to 99.9 wt. % of pyrrolidonylethyl methacrylate (PyEMA);
B. at least one cosmetically acceptable excipient; and
C. optionally, at least one personal care ingredient;
wherein the at least one copolymer has a cationic charge density in the range of 1 meq/g to 6 meq/g and has a cationic degree of substitution (Cat-DS) of greater than 0.001 units; and
wherein said at least one conditioning and/or styling copolymer has a structure selected from the group consisting of:

### Claim 2 (depends on 1)

A method for treating or fixing regular or damaged keratin substrate comprising contacting said keratin substrate with an effective amount of the personal care composition of claim 1.

### Claim 3 (depends on 1)

A method for washing or caring for keratin substrate comprising applying an effective amount of the composition of claim 1 to said keratin substrate.

### Claim 4 (depends on 1)

A method of protecting dyed hair color from fading or wash-out during exposure to air and/or shampooing which comprises contacting said dyed hair with an effective amount of the personal care composition of claim 1.
