Abstract

Solid composition useful for the production of dishwashing, laundry or cleaning compositions are comprised of (a) a hydroxy mixed ether of the formula (I) wherein R1 is a linear or branched alkyl group having from 2 to 18 carbon atoms, R2 is hydrogen or a linear or branched alkyl group having from 2 to 18 carbon atoms, R3 is a linear or branched alkyl and/or alkenyl group having from 1 to 22 carbon atoms, each of n1 and n2 independently is a number from 0 to 60 and m is 0 or a number from 0.5 to 5, with the provisos that the total number of carbon atoms in the substituents R1 and R2 is at least 6 and the sum (n1+m+n2) is greater than 0; and (b) a polymer. The compositions according to the invention can optionally contain additional nonionic surfactants, carriers, auxiliaries and additives typically found in laundry detergents, dishwashing detergents and cleaning compositions.
