Abstract
Aqueous liquid rinse-added fabric conditioning compositions comprising diamine static control agents, quaternary ammonium fabric softeners and, optionally, particulate sorbitan ester material provide fabric softening and exceptional fabric static control.
Claims11
Liquid rinse-added fabric conditioning compositions comprising:
- a. from about 0.5 to about 50% by weight of a static control agent selected from the group consisting of water-soluble acid salts of diamine compounds of the formula ##STR7## wherein n ranges from 2 to 5;
- R.sub.1 is an alkyl group containing from about 12 to 200 carbon atoms;
- and R.sub.2, R.sub.3 and R.sub.4 are each hydrogen or alkyl groups containing 1 to 20 carbon atoms, provided that at least two of R.sub.2, R.sub.3 and R.sub.4 are each hydrogen or alkyl containing from about 1 to about 3 carbon atoms, said salts having a solubility in water of at least 1 gram per liter at 25.degree. C;
- b. from about 0.5% to about 20.0% by weight of a quaternary ammonium fabric softener selected from the group consisting of compounds of the formula ##STR8## wherein R.sup.1 is an alkyl group containing from about 12 to 20 carbon atoms;
- R.sup.2 is alkyl of about 1 to 20 carbon atoms, R.sup.3 and R.sup.4 are each alkyl of about 1 to 3 carbon atoms;
- X is a non-interfering anion;
- and m is 1 when X is monovalent and m is 2 when X is divalent;
- and
- c. from about 50 to 98% by weight of water;
- said composition having a pH value within the range of from about 3 to 9.
