Washing powder compns - contng plastifiable enzyme components and non-enzyme wash-active materials

摘要

Compns. consist of min two separately prepd. powder-components of which (a) 0.5-20% consists of a homogeneous mixture of 3-30 pts. of an enzyme prepn., 25-75 pts. of the Na- or K-salt of an alkylsulphuric acid ester (8-18C alkyl), 10-50 pts. of starch and 5-20 pts. water; (b) 50-99% enzyme-free components contng. at least one cpd. of the type of anionogenic-, non-ionogenic- or zwitter-ionogenic surface-active materials and at least one cpd. of the type of inorganic and organic non-surfactant cleaning salts, as well as opt. customary wash excipients. For the full wash the compns. contain also pref. 10-40% of opt. water-contng. sodium perborate, esp. sodium perborate-tetrahydrate.
