ABSTRACT:
An extruded particulate body comprises a binder, usually having a melting point in the range 20.degree.-80.degree. C., with particulate bleach activator and particulate water-soluble disintegration aid substantially uniformly distributed throughout the body. The bleach activator is a mixture of a relatively non-surface active bleach activator, preferably tetra-acetylethylene diamine, and a relatively surface active activator, usually a C.sub.6-10 alkanoyloxy benzene sulphonate. The disintegration aid is usually a bleach stabilizor preferably a phosphonic acid or salt thereof. The extruded bodies are for incorporation into a particulate detergent formulation which contains a peroxy bleach component.
