Washing powder additives for increasing water solubility

摘要

Additives for increasing the solubility of washing powder formulations in water, added in amounts of 0.1-10 wt.%, comprise crosslinked alkoxylated alcohols prepared either by alkoxylating an alcohol with ethylene oxide (EO) and optionally propylene oxide (PO) and/or butylene oxide (BO) and then cross-linking the alkoxylated alcohol with an at least bifunctional crosslinking agent. Preferably reaction products of polyalkylene glycols with 2-6C alkylene glycol bisglycidyl ethers, or reaction products of polyethylene glycols having a weight average molecular weight of 100-2500 with a butane-1,4-diol glycidyl ether are used. The alkoxylation reaction products are addition reaction products of 1-100 moles EO, 0-30 moles PO and 0-10 moles BO with 1 mole of 1-22C alcohol. The amount of additive added is 0.5-5 wt.%. The washing powders have bulk weights of 550-1000 (at least 700) g/l.
