A powdered rinse conditioner comprising a nonionic active water insoluble cationic active having the formula: ##STR1## in which R.sub.1 is independently selected from C.sub.1-4 alkyl, hydroxyalkyl, or C.sub.2 -C.sub.4 alkenyl groups and wherein each R.sub.2 group is independently selected from C.sub.2-27 alkyl or alkenyl groups and n is an integer from 0 to 5 and relatively low levels of a long chain alcohol ethoxylate as a nonionic dispersion aid. The rinse conditioner exhibits good softening results when added directly to the wash liquor.

Novel block copolymers comprising from 20 to 95 mole % of monomer units derived from itaconic acid or a homologue thereof and from 5 to 80 mole % of monomer units derived from vinyl alcohol or a lower vinyl ester are excellent binders of divalent or polyvalent metals and are useful as potentially biodegradable builders in detergent compositions as well as in machine dishwashing compositions and anti-scaling rinse compositions.
