<p>Stable enzymatic washing up liquids Composns. consists of 2-50% of a wash-active cpd. 4-36% water, 6-60% of a polyhydroxy alcohol and 0.001-2% enzymes. The most pref. polyhydroxy alcohols are glycerol or glycol. The pref. wash-active cpds. may be anionogenic-, non-ionogenic- or ampholytic compounds such as alkali metal soaps of fatty acids C10-24) etc., water-solublising polyoxyalkylene groups combined with an organic hydrophobic group such as those derived from alkylphenols (C6-12 alkyl) etc., or alkyldimethylammoniumpropanesulphonates. The enzymes used are e.g. proteases and amylases, pref. those obtained from bacteria or moulds. The compsns. are suitable for washing-up by hand. The enzymatic activity is not reduced in aq. dilutions.</p> |
