Abstract

A hard surface cleaning composition forming upon agitation a relatively unstable emulsion breakable when applied to the hard surface to be cleaned comprising on a weight basis from about 2 to about 10% of an organic polar solvent; from about 0.1 to about 2.0% of a volatile organosiloxane; from about 0.1 to about 2.0% of a volatile surfactant having the formula: ##STR1## wherein R.sub.1 is an alkynyl of from 2 to 5 carbons; R.sub.2 is hydrogen or an alkyl of less than 4 carbons, and R.sub.3 is an alkyl or hydroxy alkyl of from 1 to 8 carbons, the total number of carbons being from 4 to 12, and water, the ratio of said volatile surfactant to said volatile organosiloxane being between about 3:1 to about 1:3. The preferred volatile surfactant is 3,5-dimethyl-1-hexyn-3-ol, while the preferred siloxane is the dimethyl siloxane cyclic tetramer.

A hard surface cleaning composition forming upon agitation an unstable emulsion breakable when applied to the hard surface to be cleaned, the composition comprising on a weight basis:

(a) from about 2 to about 10% of an organic polar solvent having a boiling point in the range of from about 75.degree. to 250.degree. C.;
(b) from 0 to about 2.5% of a nonvolatile surfactant selected from the group consisting of anionic, nonionic, amphoteric, and zwitterionic surfactants;
(c) from 0.1 to about 2.0% of a volatile organosiloxane oligomer having a boiling point in the range of from about 134.degree. to about 250.degree. C.;
(d) from about 0.1 to about 2.0% of a volatile surfactant having the formula ##STR5## wherein R.sub.1 is an alkynyl of from 2 to 5 carbons;
R.sub.2 is hydrogen or an alyl of less than 4 carbons, and R.sub.3 is an alkyl or hydroxy alkyl of from 1 to 8 carbons, the total number of carbons in the molecule being from 4 to 12, and
