Abstract
Alkyl polyglycoside containing industrial and institutional liquid cleaning compositions which provide for the elimination, or the reduction in the amount, of stabilizing agents.
Claims21
An industrial and institutional liquid cleaning composition which comprises:
- (a) from about 1% to about 30% active by weight of a 1:1 to 1:0 mixture of an alkyl polyglycoside in which the alkyl group contains 12 to 16 carbon atoms to an alkyl polyglycoside in which the alkyl group contains 8 to 10 carbon atoms;
- (b) from 0% to about 50% by weight of an alkali metal hydroxide;
- (c) from 0% to about 40% by weight of an alkali metal silicate;
- (d) from 0% to about 40% by weight of a builder;
- (e) from 0% to about 5% by weight of a dispersing/antiredeposition agent;
- (f) from about 5% to about 75% by weight of water;
- and
- (g) from 0% to about 5% by weight of a hydrotrope, with the proviso that the sum of the percentages for the alkali metal hydroxide, alkali metal silicate and the builder must be greater than zero;
- and wherein the composition is free from ethoxylated alcohols and alkylphenol ethoxylates.

- (f) from about 5% to about 75% by weight of water;
- and
- (g) from 0% to about 5% by weight of a hydrotrope;
- with the proviso that the sum of the percentages for the alkali metal hydroxide, alkali metal silicate and the builder must be greater than zero.
