The invention relates to the use of an aqueous polymer dispersions, which are obtainable by radical aqueous emulsion polymerization in the presence of a degraded starch as an opacifier in liquid formulations, in particula in liquid detergent formulations and liquid cosmetic preparations. The invention also relates to a process for producing the aqueous polymer dispersions. Further, the invention also relates to liquid formulations such as detergent formulations and liquid cosmetic preparations, which contain at least one aqueous polymer dispersion. The aqueous polymer dispersions are obtainable by radical aqueous emulsion polymerization of i) ethylenically unsaturated monomers M comprising or in particular consisting of a) at least 70% by weight, in particular at least 75% by weight, especially at least 80% by weight, based on the total weight of monomers M, of at least one monomer Ma, selected from the group consisting of monovinylaromatic monomers, and optionally b) up to 30% by weight, in particular up to 25% by weight, especially up to 20% by weight, based on the total weight of monomers M, of one or more ethylenically unsaturated monomers Mb, which are different from the monomer Ma; in the presence of ii) 50 to 300% by weight, in particular 70 to 250% by weight, especially 80 to 200% by weight, based on the total amount of monomers M, of a degraded starch. |
