Abstract (en)

[origin: WO2013092276A1] One aspect of the invention relates to a detergent composition comprising 20-99.7 wt.% of a continuous phase containing glutamic-N,N-diacetate (GLDA), water and optionally other components; and 0.3-80 wt.% of a dispersed phase comprising at least 0.3% of bleach particles by weight of the composition, said bleach particles having a particle size of at least 10 mum, wherein the continuous phase contains at least 10 wt.% of GLDA and at least 10 wt.% of water and wherein the weight ratio of GLDA to water lies within the range of 5:6 to 5:1. Despite the high water content, the present bleach containing detergent composition is storage stable and retains bleach activity for a prolonged period of time. The invention also provides a process of preparing a liquid base for a detergent composition comprising GLDA and water in a weight ratio of GLDA to water of 5:6 to 5:1, said process comprising combining 100 parts by weight of a liquid mixture of GLDA and water with 10-300 parts by weight of GLDA powder, said liquid mixture containing 20-50 wt.% of GLDA and 50-80 wt.% water and said GLDA powder containing at least 65 wt.% GLDA.
