Abstract (en)
[origin: WO2022243264A1] The present invention relates to a process for preparing of a particulate, free flowing detergent particle by a slurry making and spray drying technique. In particular it relates to the process for preparing a slurry with lower alkalinity for the production of spray dried laundry detergent particle. Accordingly, it is one object of this invention to provide a process for preparing a spray dried detergent particle where the spray dried particle has excellent powder properties and provides a wash liquor with lower alkalinity and provides good stain removal performance without being harsh on hands and fabrics.. The present inventors have found that a spray-dried detergent particle having a combination of silicate salt and/or disilicate salt of alkaline earth metal, alkali metal silicate and low levels of carbonate salt prepared by a process where the silicate and/or disilicate salt of alkaline earth metal is formed in-situ provides for excellent powder properties with extended shelf life without getting caked and the spray-dried particles provides desired pH in wash solution to provide for good stain removal performance without being harsh on the hands or the fabrics.
