Claims14
A cleaning composition in the form of a stable, water-in-oil emulsion consisting essentially of
- from 0.5 to 5 wt. % of at least one surface-active agent selected from the group consisting of ammonium salts of C8 to C12 alkylbenzenesulfonates and mixtures of at least one fatty acid alkanol amide corresponding to the formula
- R.sup.1 --CO--N(R.sup.2)--(CH.sup.2).sub.n --OH
- wherein R.sup.1 --CO is a saturated or unsaturated C12 to C18 fatty acid group, R.sup.2 is hydrogen or a --(CH.sub.2).sub.n --OH group, and n is an integer from 1 to 6
- and at least one C8 to C12 alkylphenol polyglycol ether containing from 5 to 8 ethylene oxide units, and
- from 80 to 99 wt. % of 1,1-dichloro-1-monofluoroethane,
- from 0.5 to 15 wt. % water, and
- from 0 to 2 wt. % ammonia;
- the sum of the components being 100 wt. %.
