Abstract
Fabric softener compositions that include a quaternary ammonium ester fabric softening active, dispersed perfume, and a pentaerythritol ester, the compositions exhibiting viscosity stability while also delivering the softening benefits that are desired by consumers. Methods of making same.
Claims16
A liquid fabric softener composition, comprising by weight of the composition:
- from about 2% to about 25% of a quaternary ammonium ester softening active;
- from about 0.1% to about 7% of dispersed perfume;
- and
- from about 0.1% to about 5% of a pentaerythritol ester according to formula
- wherein each of R1, R2, R3, and R4 is independently selected from C3-C15 linear or branched, saturated or unsaturated, alkyl chains.
2 more elements
The liquid fabric softener composition according to 1, wherein the quaternary ammonium ester softening active has the following formula:
- {R2(4-m)—N+-[X—Y—R1]m}A-
- wherein:
- m is 1, 2 or 3 with proviso that the value of each m is identical;
- each R1 is independently hydrocarbyl, or branched hydrocarbyl group;
- each R2 is independently a C1-C3 alkyl or hydroxyalkyl group;
- each X is —CH2—CH(CH3)— or —CH(CH3)—CH2—;
- and
- each n is independently 1, 2, 3 or 4;
- each Y is independently —O—(O)C— or —C(O)—O—;
- A- is independently selected from the group consisting of chloride, methyl sulfate, and ethyl sulfate;
- with the proviso that when Y is —O—(O)C—, the sum of carbons in each R1 is from about 13 to about 21.
