PROCESS FOR PREPARING A SPRAY DRIED DETERGENT PARTICLE

The present invention relates to a process for preparing a spray-dried detergent particle. Particularly to spray-dried laundry detergent particles with low pH, low alkalinity and have good particle characteristics. It is thus an object of the present invention to provide a process for preparing a spray dried detergent particle having low pH and low alkalinity. It is yet another object of the present invention to provide a spray dried detergent particle with low levels of alkaline builders such as carbonate and silicate and yet having good powder properties over extended storage periods.The present inventors have found that a spray dried detergent particle having an aqueous slurry having one or more ingredients selected from the group consisting of a carboxylic acid salt of aluminium, an aluminium complex of carboxylic acid or mixtures thereof provides for excellent powder properties and extended shelf life without getting caked. It is also surprisingly found that the spray-dried particle provides desired pH in wash solution required for good stain removal performance without being harsh on the hands or the fabrics.
