Washing and cleaning agents

摘要

Washing and cleaning agents containing a combination of dextrin and alkali percarbonate-containing bleaching agent. The dextrin preferably has an average molecular weight of 440-500,000 and a dextrose equivalent of 0.5-40 (2-30). Preferably the washing agent contains 0.5-10 (2-7) wt. % dextrin and 10-30 (15-25) wt. % alkali percarbonate, especially where the weight ratio of dextrin to alkali percarbonate is 1:1 to 1:8, especially 1:2 to 1:5. The washing agent preferably contains alkali carbonate in addition to alkali percarbonate, especially where the weight ratio of dextrin to the sum of alkali percarbonate and alkali carbonate is 1:1 to 1:10, especially 1:2 to 1:7. The washing agent preferably also contains 5-50 (8-30) wt. % surfactants and up to 60 wt. %, preferably 5-40 wt. % total builders.
