Abstract

Liquid conditioning compositions that include alkyl ester quaternary ammonium (“ester quat”) softening actives, where the ester quat softening actives are derived in part from trans-unsaturated fatty acids, such as elaidic acid. Related methods and uses.

First claim

What is claimed is:

1. A liquid conditioning composition comprising:
from about 2% to about 20%, by weight of the composition, of an alkyl ester quaternary ammonium (“ester quat”) softening active,
wherein the ester quat softening active is derived from a fatty acid feedstock derived from plants,
wherein the fatty acid feedstock comprises from about 15% to about 25%, by weight of the fatty acid feedstock, of C16 fatty acids, and wherein the fatty acid feedstock comprises fatty acids that are derived from cottonseed,
wherein the fatty acid feedstock comprises from about 6% to about 12%, by weight of the fatty acid feedstock, of trans-unsaturated fatty acids,
wherein the trans-unsaturated fatty acids comprise elaidic acid, and
wherein elaidic acid is present at a level of:
(a) about 4% to about 20%, by weight of the fatty acid feedstock, and/or
(b) about 50% to about 100%, by weight of the trans-unsaturated fatty acids.

2. The liquid conditioning composition according to claim 1 , wherein elaidic acid is present at a level of:
(a) about 4% to about 15%, by weight of the fatty acid feedstock, and/or
(b) about 75% to about 100%, by weight of the trans-unsaturated fatty acids.

3. The liquid conditioning composition according to claim 1 , wherein the fatty acids of the fatty acid feedstock comprise cis-unsaturated fatty acids, and wherein the weight ratio of the cis-unsaturated fatty acids to the trans-unsaturated fatty acids (“cis:trans ratio”) is about 1:2 to about 1:1.6.

4. The liquid conditioning composition according to claim 1 , wherein the fatty acid feedstock is characterized by an iodine value of about 5 to about 60.

5. The liquid conditioning composition according to claim 1 , wherein the composition comprises about 2% to about 15%, by weight of the composition, of the ester quat softening active.

6. The liquid conditioning composition according to claim 1 , wherein the ester quat softening active comprises about 10% to about 30%, by weight of the ester quat softening active, of triester quat material.

7. The liquid conditioning composition according to claim 1 , wherein the liquid conditioning composition further comprises a treatment adjunct selected from the group consisting of: additional conditioning agents, dyes, pH control agents, solvents, rheology modifiers, structurants, cationic polymers, surfactants, perfume, perfume delivery systems, chelants, antioxidants, preservatives, or mixtures thereof.

8. The liquid conditioning composition according to claim 1 , wherein the liquid conditioning composition comprises less than 0.1%, of a rheology modifier, a structurant, or a mixture thereof.

9. The liquid conditioning composition according claim 1 , wherein the liquid conditioning composition comprises an antioxidant.

10. The liquid conditioning composition according to claim 1 , wherein the liquid conditioning composition is characterized by a viscosity of about 50 cps to about 300 cps.

11. A method of treating a surface, the method comprising the step of contacting a surface with a liquid conditioning composition according to claim 1 , optionally in the presence of water.

12. The method according to claim 11 , wherein the surface is a fabric comprising cotton fibers.
