    Abstract: 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.

    Abstract: The present invention relates to aqueous polymer compositions, which are obtainable by radical copolymerization in water of i) ethylenically unsaturated monomers M comprising a.1) 50 to 95% by weight, in particular 60 to 93% by weight, more particularly 70 to 92% by weight, especially 75 to 90% by weight, based on the total weight of the monomers M, of at least one monomer M1, selected from the group consisting of C1-C3-alkyl esters of acrylic acid and C1-C3-alkyl esters of methacrylic acid and mixtures thereof, and a.2) 5 to 50% by weight, in particular 7 to 40% by weight, more particularly 8 to 30% by weight, especially 10 to 25% by weight, based on the total weight of the monomers M, of at least one monomer M2, selected from the group consisting of monoethylenically unsaturated C3-C8-monocarboxylic acids and monoethylenically unsaturated C4-C8-dicarboxylic acids, and mixtures thereof; in the presence of ii) 110 to 600 by weight, in particular 130 to 500% by weight, more particularly 150 to 480% by weight and especially 170 to 450% by weight, based on the total amount of monomers M, of a carboxymethylcellulose. Further aspects of the present invention relate to a process for producing the aqueous polymer compositions of the present invention; - the use of the aqueous polymer compositions as defined herein as an anti-grey- ing additive in the washing or laundry; - the use of the aqueous polymer compositions as defined herein as an anti-grey- ing additive in laundry detergent formulations, in particular in liquid laundry detergent formulations or gel-type laundry detergent formulations; laundry detergent formulations, in particular a liquid or gel-type laundry detergent formulations, which contain at least one aqueous polymer composition as defined herein.

    Abstract: The present invention relates to dispersions of cellulose acetate (CA), a process to produce CA-dispersions and the CA-dispersion obtainable from such process, and the use of such CA-dispersions as opacifiers in formulations or compositions within the field of application of fabric and home care, industrial and institutional cleaning, cosmetics, personal care, lacquer and colorants formulations, agricultural active formulations; such process comprising steps of adding certain solvent mixture, a feed mixture and optionally a further solvent feed, the feed mixture comprising dissolved CA, such mixtures and feeds being added to a mixing zone at certain ratios and contents such that the overall ratio of the various solvents are maintained at a specific ratio throughout the additions and mixing, de- agglomerating the CA-dispersion obtained, removing at least partially organic solvent employed in the previous steps, optionally adding additives and/or stabilizer, optionally further reducing the amounts of organic solvent(s) present, optionally further imparting shear energy to obtain smaller particle sizes and preferably a narrower particle size distribution of the dispersed CA within the CA-dispersion, and optionally drying the CA-dispersion to a fine-particulate CA-powder.
