Abstract
An improved detergent mixture for cleaning hard surfaces comprising a mixture of a non-ionic detergent, a tertiary amine oxide, and a quaternary dimethyl ammonium halide. The mixture having a particular combination of ingredient concentrations described exhibits improved detergency compared with compositions containing only one or two of these ingredients at equivalent concentrations.
Claims6
A detergent concentrate composition comprising:
- A. about 1.5-2.0% by weight of a non-ionic detergent which is a condensation product of about 8-16 moles of ethylene oxide with one mole of a compound selected from the group consisting of
- 1. an alkyl phenol having about 7-10 carbon atoms in the alkyl group;
- 2. an alkyl amine having about 12-16 carbon atoms in the alkyl group;
- and
- 3. an aliphatic alcohol having about 12-16 carbon atoms;
- B. about 0.25-0.30% by weight of an alkyl dimethyl amine oxide in which the alkyl group has about 12-16 carbon atoms;
- C. about 0.30-0.40% by weight of a quaternary ammonium halide having the formula ##STR2## where R.sub.1 and R.sub.2 are methyl;
- R.sub.3 is methyl or a phenyl-substituted alkyl group having about 8-12 carbon atoms;
- and R.sub.4 is an alkyl group having about 12-18 carbon atoms;
- D. about 5-5.8% by weight of an alkaline inorganic builder selected from the group consisting of the alkali metal carbonates, phosphates, and borates;
- and
- E. a defoaming agent in an amount effective to control foaming of the composition in use;
- and
- F. the remainder water.
