Abstract:
Aqueous fabric softener composition comprising:(A) cationic fabric softening compound having the formula: (R)4âˆ’mâ€”N+â€”[(CH2)nâ€”Yâ€”R2]mXâˆ’wherein each Y&boxH;â€”Oâ€”(O)Câ€”, â€”C(O)â€”Oâ€”, â€”NRâ€”(O)Câ€”, or â€”C(O)â€”NRâ€”; m=2 or 3; each n=1 to 4; each R substituent is a short chain C1-C6 alkyl, hydroxyalkyl, or benzyl group or mixtures thereof; each R2 is a long chain, C11-C21 hydrocarbyl, or substituted hydrocarbyl substituent and the counterion, Xâˆ’, is any softener-compatible anion; wherein said cationic fabric softening compound is in the composition in the form of vesicles; and (B) at least an effective amount of cationic polymer to improve the softening of the cationic fabric softening compound, said cationic polymer being water soluble to the extent of at least 0.5% by weight at 20Â° C. and having a concentration in the aqueous phase of from about 0.001% to about 10%; wherein the vesicles are formed prior to introduction of the cationic polymer into the composition.
