Abstract:
Storage-stable compositions comprising soil release polymers. Compositions are described comprising A) of from 45 to 55% by weight of one or more polyesters according to the following formula (I) wherein R and R2 independently of one another are X—(OC2H4) n—(OC3H6)m wherein X is C1-4alkyl, the —(OC2H4) groups and the —(OC3H6) groups are arranged block-wise and the block consisting of the —(OC3H6) groups is bound to a COO group or are HO—(C3H6) n is based on a molar average a number of from 12 to 120, m is based on a molar average a number of from 1 to 10, and a is based on a molar average a number of from 4 to 9, and B) of from 10 to 30% by weight of one or more alcohols selected from the group consisting of ethylene glycol, 1,2-propylene glycol, 1,3 -propylene glycol, 1,2 -butylene glycol, 1,3 -butylene glycol, 1,4 -butylene glycol and butyl glycol and C) of from 24 to 42% by weight of water, the amounts in each case being based on the total weight of the composition. The compositions may advantageously be used in laundry detergent and fabric care products. Process for making laundry liquid compositions comprising said active blend.
