Abstract

Abstract The invention pertains to a particulate detergent composition comprising a detergent active system consisting of a fatty acid soap component having a Krafft temperature of below 30° C. and an alkoxylated alcohol nonionic component having an HLB value of between 12 and 16, an alkaline buffering agent and a builder. The composition provides a particulate product, which is easily water-dissolvable without any significant agitation to form stable concentrated alkaline stock-solutions.
