Abstract

A batch process for the preparation of detergent powder of high bulk density comprises neutralising a detergent acid (anionic surfactant precursor), eg linear alkylbenzene sulphonic acid, with a particulate solid water-soluble alkaline inorganic material, for example, sodium carbonate (optionally plus other alkaline materials and/or detergency builders, for example, alkali metal aluminosilicate), in a high-speed mixer/granulator, eg Fukae mixer, and granulating the product in the mixer.
The reaction mixture remains particulate throughout the process, without the need to keep the temperature during the neutralisation step to 55°C or below, and a high-quality high-bulk-density particulate product is obtained.
