Washing and cleaning powders with enzyme coated particles

摘要

Washing and cleaning powders with enzyme-coated particles The powders consists of at least 2 separately made constituents, namely 1 to 20% of enzyme-coated washing powder particles (A), 50-99% of enzyme-free washing powder particles (B) and 0 to 35% powder particles of a per compound (C). (A) is 40 to 60 parts pentasodium triphosphate, 10 to 40 parts sodium sulphate, 0 to 12 parts disodium hydrogen phosphate, 1 to 10 parts of an enzyme prepn. 4 to 12 pts. water (mainly as water of crystallisation), and 3 to 8 parts of an addn. product of 6 to 12 mols ethylene oxide on 1 mol of an alcohol or alkyl phenol with 14 to 18C atoms. (B) contains at least one anionic, non-ionic or amphoteric detergent and at least one organic or inorganic cleaning salt which is not a surface active agent. The compsns. are free-flowing and do not tend to cake, dust or separate. The enzyme activity is maintained over long storage periods. They are esp. for fully automatic washing machines.
