Abstract
Liquid fabric softening compositions generally comprise: (a) a fabric softening active system comprising at least two fabric softening actives, preferably cationic fabric softening actives, each having a recrystallization onset temperature; wherein the recrystrallization onset temperature of a first fabric softening active is at least about 5° C., preferably at least about 10° C., more preferably at least about 15° C., and even more preferably at least about 20° C., below the recrystallization onset temperature of a second fabric softening active; (b) liquid carrier, typically aqueous-based, to act as a continuous phase for the formation of a dispersion; and (c) optional ingredients.
Claims23
A liquid fabric softening composition comprising:
- (a) a fabric softening active system comprising at least two fabric softening actives, each having a recrystallization onset temperature;
- wherein the recrystrallization onset temperature of a first fabric softening active is at least about 5° C. below the recrystallization onset temperature of a second fabric softening active;
- (b) liquid carrier to act as a continuous phase for the formation of a dispersion;
- and
- (c) optional ingredients.
A method of formulating a liquid fabric softening composition having improved freeze/thaw cycling characteristics or for providing improved absorbency in fabrics treated with the composition, the method comprising the steps of:
- providing a fabric softening active system comprising at least two fabric softening actives, each having a recrystallization onset temperature;
- wherein the recrystrallization onset temperature of a first fabric softening active is at least about 5° C. below the recrystallization onset temperature of a second fabric softening active;
- mixing the fabric softening active system in a fluid medium to form a dispersion;
- and
- optionally mixing additional ingredients into the fabric softening active system or dispersion.
A process for making cationic softening actives, the process comprising the steps of:
- (a) blending fatty acids having an iodine value of from about 10 to about 60 with fatty acids having an iodine value of from about 70 to about 140 to form a mixture of fatty acids;
- (b) reacting the mixture with an amine to form a reaction product;
- and
- (c) quaternizing the reaction product.
