Process for preparing a spray-dried laundry detergent particle

The present invention relates to a process for preparing a spray-dried laundry detergent particle, wherein the process includes the step of contacting water-insoluble 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 includes detersive surfactant, wherein the aqueous mixture is substantially free of carbonate salt, wherein the water-insoluble 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.

Low-foaming warewash detergent containing mixed cationic / nonionic surfactant system for enhanced oily soil removal

The invention includes ware detergent compositions which provides superior cleaning and removal of oily and fatty soils, without the production of excessive foam. According to the invention applicants have discovered that use of a quaternary cationic surfactant in combination with a nonionic low foaming surfactant can provide oily soil removal from ware that is superior to traditional warewash detergent formulations. Compositions for alkaline, preferably solid, warewash detergents are disclosed, as well as their use in dish machines and methods of manufacture.
