Process for making a detergent composition comprising a hydrophilic silica and a copolymer containing a carboxylic acid monomer and a sulfonic acid monomer

摘要

A process for making a detergent composition, the detergent composition comprising: a) from about 0.1% to about 50% by weight of the composition of a polymer in particulate form comprising: i) a carboxylic acid monomer; ii) more than about 5% by weight of the polymer of a sulfonic acid monomer; and iii) optionally a non-ionic monomer; and b) from about 0.01% to about 10% by weight of the composition of a hydrophilic silica. the process comprising the steps of: a) pre-mixing the polymer with the hydrophilic silica to obtain a polymer/silica premix; and b) mixing polymer/silica premix with any additional detergent components.
