Abstract (en)
The present invention relates to a process for preparing a spray-dried laundry detergent particle, wherein the process comprises the step of contacting water-soluble silicate salt to monomeric organic carboxylic acid in an aqueous mixture, wherein the aqueous mixture has a pH of 4.2 or less, wherein the aqueous mixture comprises detersive surfactant, wherein the aqueous mixture is substantially free of carbonate salt, wherein the water-soluble silicate salt reacts with the monomeric organic carboxylic acid to form silica, wherein the aqueous mixture is spray-dried to form a spray-dried laundry detergent particle, wherein the particle comprises: detersive surfactant; monomeric organic carboxylic acid; and silica, wherein the particle is substantially free of carbonate salt.
