Unit dose fabric softener
A unit dose fabric conditioner that contains a combination of a polyol, alkoxylated alcohol, and dispersing polymer to allow for incorporation of encapsulated fragrance slurries into unit dose fabric conditioners to disperse the encapsulated fragrance and fabric conditioner active during laundering.
1. A unit dose fabric conditioner comprising a fabric conditioner composition contained within a water soluble pouch, wherein the composition is liquid at 25° C. and comprises:
a) a cationic fabric softening active, wherein the cationic fabric softening active is at least one active chosen from esterquat, tallow esterquat, triolyeyl esterquat, and diolyeyl esterquat;
b) at least 50% by weight of the composition of a C 3 -C 12 polyol that is liquid at 25° C.;
c) a C 9 -C 15 alkoxylated alcohol having an average of 3 to 8 EO per mole and which is liquid at 25° C.;
d) a dispersing polymer for dispersing the cationic fabric softening active; and
encapsulated fragrance;
wherein the alkoxylated alcohol is present in an amount of 2.6 to 7.1% by weight of the composition; and
wherein the dispersing polymer is present in an amount of 1.6 to 5.8% by weight of the composition.
2. The unit dose fabric conditioner of claim 1 , wherein the water soluble pouch comprises polyvinyl alcohol.
3. The unit dose fabric conditioner of claim 1 , wherein the composition further comprises free fragrance, and wherein the free fragrance is present in an amount of 0.5 to 7% by weight of the composition.
4. The unit dose fabric conditioner of claim 1 , wherein the encapsulated fragrance is present in an amount of 1 to 10% by weight of the composition.
5. The unit dose fabric conditioner of claim 1 , wherein the cationic fabric softener is present in an amount of 10 to 30% by weight of the composition.
