ABSTRACT:
A detergent having improved detergency particularly with respect to greasy soil comprising (a) a mixture of water-insoluble nonionic surfactants, (b) a water-soluble anionic surfactant of the sulfonate or sulfate type, (c) a detergent builder and (d) other standard detergent ingredients. The nonionic surfactant comprises a mixture of (i) an ethoxylated C.sub.16 -C.sub.18 alcohol with 4 to 6 glycolether groups, (ii) an ethoxylated C.sub.10 -C.sub.14 alcohol with 4 to 6 glycolether groups and (iii) an ethoxylated C.sub.10 -C.sub.18 alkylamine with 1 to 3 glycolether groups. The nonionic surfactant is adsorbed on a granular carrier material which is soluble or dispersible in water. The weight ratio of constituent (i) to constituent (ii) to constituent (iii) is within the range of 1:2(2-6):(0.8-2.5) and the weight ratio of the nonionic surfactant to the anionic surfactant is within the range of 4:1 to 4:3. The carrier material preferably comprises a spray-dried mixture of from 60 to 80% zeolite, from 3 to 20% of a copolymeric carboxylic acid, from 0.1 to 3% sodium silicate and water and may contain up to 40% by weight of nonionic surfactant. The carrier material which is impregnated with the nonionic surfactant is combined with other, optionally spray-dried powder constituents containing the other components to form a homogeneous powder mixture.
