Abstract:
A paste-form detergent composition that is substantially free of water and comprises a solid phase dispersed in a liquid phase, said detergent composition containing (A) 20% to 58% by weight of a liquid surfactant component comprising a nonionic surfactant (B) 2% to 40% by weight of solid builders, and (C) 2% to 40% by weight of a solid bleaching component comprising a peroxygen-containing oxidizing agent and a bleach activator, based on the weight of the composition, wherein the paste-form detergent composition has a viscosity, at 20.degree. C. of from 70,000 mPas to 110,000 mPas, as measured with a Brookfield rotational viscometer at 5 r.p.m, wherein the liquid phase comprises the liquid surfactant component (A), said liquid surfactant component comprising a nonionic surfactant or surfactants selected from the group consisting of ethoxylated and optionally propoxylated alcohols corresponding to formula I:R.sup.1 --(OC.sub.2 H.sub.4).sub.m --(OC.sub.3 H.sub.6).sub.n --OH (I)in which R.sup.1 is an alkyl or alkenyl group containing 6 to 11 carbon atoms, m has a value of 3 to 15 and n has a value of 0 to 6, and formula II:R.sup.2 --(OC.sub.2 H.sub.4).sub.o --(OC.sub.3 H.sub.6).sub.p --OH (II)in which R.sup.2 is an alkyl or alkenyl group containing 12 to 22 carbon atoms, o has a value of 3 to 15 and p has a value of 0 to 6, and wherein the solid phase comprises the builder and bleaching components (B) and (C) in fine particulate form having a mean particle size of 5 to 200 .mu.m and no more than 10% by weight of the particles are larger than 200 .mu.m.
