Claims22
A fabric softening and anti-static composition comprising a softening amount of an alkyl ammonium carbamate compound of the formula
- R.sub.1 R.sub.2 NH.sub.2 .sup.+O.sup.-(O)CNR.sub.3 R.sub.4
- wherein R.sub.1 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, R.sub.2 is an alkyl group having from 6 to 9 carbon atoms, R.sub.3 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, and R.sub.4 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, provided the sum of the carbon atoms in R.sub.1, R.sub.2, R.sub.3, and R.sub.4 is at least 10;
- and sufficient suspending agent to suspend said alkyl ammonium carbamate in water.
A combined fabric softening and detergent composition comprising a softening amount of an alkyl ammonium carbamate compound of the formula
- R.sub.1 R.sub.2 NH.sub.2 .sup.+O.sup.-(O)CNR.sub.3 R.sub.4
- wherein R.sub.1 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, R.sub.2 is an alkyl group having from 6 to 9 carbon atoms, R.sub.3 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, and R.sub.4 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, provided the sum of the carbon atoms in R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is at least 10;
- and a detersive amount of a water-soluble detersive surfactant compound.
A dryer-added fabric softener comprising a fabric softening amount of an alkyl ammonium carbamate of the formula
- R.sub.1 R.sub.2 NH.sub.2 .sup.+O.sup.-(O)CNR.sub.3 R.sub.4
- wherein R.sub.1 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, R.sub.2 is an alkyl group having from 6 to 9 carbon atoms, R.sub.3 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, and R.sub.4 is hydrogen or an alkyl group having from 1 to 9 carbon atoms, provided the sum of the carbon atoms in R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is at least 10, in releasable combination with a dispensing means comprising a sheet of paper or woven or non-woven cloth.
