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.
