Abstract

A free-flowing granular detergent component or composition having a bulk density of at least 650 g/l which comprises (i) at least 35 % by weight of anionic surfactant; (ii) 0.5 % to 10 % by weight of a chelating agent; (iii) 0.5 % to 30 % by weight of a polymer or co-polymer wherein the weight ratio of chelating agent to polymer/co-polymer is from 1:100 to 1:1. A process for making the granular detergent component or composition is also described. It is an essential feature of this process that aqueous solutions of a chelating agent and a polymer or co-polymer are added to a high active surfactant paste.
