Abstract
Concentrated, liquid fabric-softening compositions containing 15-60% of a cationic fabric-softening agent, and an aqueous medium, are prepared by inclusion therein of an effective amount of polymer, such as polyethyleneglycol with a molecular weight of 6,000. These compositions are water-dispersible and pourable, and can be easily dosed into the rinse cycle of a washing process, e.g. by means of automatic dosing devices in the washing machine.
Claims22
An aqueous, liquid concentrated fabric-softening composition comprising from 25-75% by weight of an aqueous medium, from 15-60% by weight of a cationic softening agent which is a quaternary ammonium compound containing at least one C.sub.12 -C.sub.22 alkyl- or alkenyl group, said alkyl- or alkenyl group not being linked through an ester linkage, and from 4 to 25 by weight of a polymer, said polymer being water-soluble, having a viscosity (20% aqueous solution at 25.degree. C. and 110 sec..sup.-1 in a Haake Viscometer) of 50 or less cP, having a vapor pressure (20% aqueous solution ) equal to or lower than the vapor pressure of a 2% aqueous solution of polyethyleneglycol with a molecular weight of 6,000, said polymer having a molecular weight of at least 400.
