Claim 2
Dependent Claim
79 words
A fabric treatment composition comprising A. from about 0.1% to about 10% by weight of i. a condensation product of (a) an aliphatic dicarboxylic acid, or an ester- or amide-forming derivative thereof; (b) a hydroxypolyoxy-alkylene compound containing at least one polyalkylene chain consisting of a plurality of oxyalkylene radicals linked directly to one another, or an ester- or amide-forming derivative thereof; and (c) a compound selected from the groups 1. an aliphatic or cycloaliphatic amino acid or lactam, 2.
Claim 3
Dependent Claim
89 words
an aliphatic or cycloaliphatic diamine or salt thereof with aliphatic dicarboxylic acid, 3. a mixture of the amino acid or lactam compound with the diamine compound or salts thereof, and 4. an ester- or amide-forming derivative of reactants 1), 2) or 3) above; or ii. a reaction product of an alkylene oxide with polyamide; in an admixture with P. from about 1% to about 60% by weight of a cationic fabric softener compound having a solubility in water not greater than 500 parts per million at 25° C and
