METHOD FOR PRODUCING GRANULATED OR POWDERY DETERGENT COMPOSITIONS

摘要

There is provided a method for producing granulated or powdery detergent compositions comprising adding into slurry a copolymer obtained by radical copolymerisation of (A) 50-99.5 mol % monoethylenically unsaturated monocarboxylic acid or the salt thereof, (B) 0.5-20.0 mol % monoethylenically unsaturated alkoxylated monomer of formula (I) (see formula I) in which the variables are defined as follows: R1 is hydrogen or methyl; R2 is -(CH2)x-O-, -CH2-NR5-, -CH2-O-CH2-CR6R7-CH2-O- or -CONH-; R3 is a C2-alkylene radical; R4 is hydrogen, -SO3M or -PO3M2; R5 is hydrogen or -CH2-CR1=CH2; R6 is -O-[R3-O]n-R4; R7 is hydrogen or ethyl; M is alkali metal or hydrogen; n is from 4 to 250; x is 0 or 1.
