ABSTRACT:
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; andiii) optionally a non-ionic monomer; andb) from about 0.01% to about 10% by weight of the composition of a hydrophobic silica the process comprising the steps of:a) pre-mixing the polymer with the hydrophobic silica to obtain a polymer/silica premix; andb) mixing polymer/silica premix with any additional detergent components.
