Abstract

Disclosed is a hair conditioning composition comprising by weight: (a) from about 0.1% to about 15% of a silicone polymer containing quaternary groups wherein said silicone polymer comprises silicone blocks with greater than about 200 siloxane units; (b) a solvent for the silicone polymer which is a silicone copolyol, at a level such that the weight % of the silicone copolyol in its mixture with the quaternized silicone polymer is in the range of from about 1% to about 50%; (c) from about 0.001% to about 0.1% of a carbamate preservative; (d) an aqueous carrier.

Claims

1. A hair conditioning composition comprising by weight:

(a) from about 0.1% to about 15% of a silicone polymer containing quaternary groups wherein said silicone polymer comprises silicone blocks with greater than about 200 siloxane units;

(b) a solvent for the silicone polymer which is a silicone copolyol, at a level such that the weight % of the silicone copolyol in its mixture with the quaternized silicone polymer is in the range of from about 1% to about 50%;

(c) from about 0.001% to about 0.1% of a carbamate preservative;

(d) an aqueous carrier.

2. The hair conditioning composition of claim 1 comprising from about 0.01% to about 0.02% of a carbamate preservative.

3. The hair conditioning composition of claim 1, wherein the carbamate preservatives are alkynyl carbamates of formula (I):

4. The hair conditioning composition of claim 3, wherein the carbamate preservatives are the alkynyl carbamates of formula (I), wherein X denotes an iodine atom and R denotes a lower alkyl group containing from 1 to 4 carbon atoms.

5. The hair conditioning composition of claim 4, wherein the carbamate preservative is 3-iodo-2-propynyl butylcarbamate.

6. The hair conditioning composition of claim 1, wherein the composition is substantially free of paraben preservatives.

7. The hair conditioning composition of claim 1, wherein the composition is substantially free of salt preservatives and acid preservatives

8. The hair conditioning composition of claim 1, wherein said quaternized silicone polymer corresponds to the following formula:

A¹-B-(A²-B)_m-A¹

wherein,

B is a silicone block with greater than about 200 siloxane units;

A² is a non-silicone block containing quaternary nitrogen groups;

A¹ is an end group; and

m is an integer 0 or greater; and

wherein when m is 2 or greater, each A² independently can be the same or different.

9. The hair conditioning composition of claim 1, wherein the quaternized silicone polymer has the following structure (XIII)

10. The hair conditioning composition of claim 1 further comprising:

(e) from about 0.1% to about 10% by weight of the composition of a cationic surfactant; and

(f) from about 1% to about 20% by weight of the composition of a high melting point fatty compound;

wherein the cationic surfactant, the high melting point fatty compound, and the aqueous carrier form a gel matrix.

11. The hair conditioning composition of claim 10, wherein the composition is substantially free of diol preservatives.

12. The hair conditioning composition of claim 10, wherein the composition is substantially free of anionic surfactants and anionic polymers.
