    • A single phase aerosol composition comprising the following constituents: (a) 5 to 75 wt % of a hydrofluorocarbon(s) (HFC) of vapor pressure greater than or equal to 4 bar at 20° C. (60 psig at 70° F.); (b) 10 to 30 wt % of a hydrocarbon propellant; (c) 1 to 70 wt % of a hydrocarbon solvent(s) with a vapor pressure of less than 0.1 mm Hg at 20° C.; (d) 0.01 to 10 wt % of an active constituent(s) selected from the group which includes fragrances, air-sanitisers, air fresheners, deodorizers, odor eliminators, malodor counteractants, insecticides, insect repellants, medicinal substances, disinfectants, aroma therapy compositions; and, (e) 0 to 25 wt % of an adjuvant constituent(s) other than (a), (b), (c) or (d). Methods of making the said composition and aerosol dispensers containing the said composition are also disclosed.

    • Provided are an acidic hard surface cleaning composition which includes: a surfactant system which includes one or more of anionic, cationic, nonionic, amphoteric or zwitterionic surfactants in amounts of at least 0.01% wt, preferably in amounts of between in excess of 1% wt, to 30% wt., with the proviso that if a cationic surfactant is present, is it present in an amount of in excess of 1% wt, more preferably in an amount of at least 1.1% wt; a volatile hydrocarbon having a volatility greater than that of water, and preferably wherein the volatile hydrocarbon has a vapor pressure of 0.2 mniHg or more at 20° C. in amount effective to impart motility when the composition is applied as a film or laminar layer to a hard surface at normal atmospheric conditions (‘sea level’) and at ambient temperature (approx. 20° C.); an acid constituent which includes one or more acids, including one or more organic or inorganic acids in an amount effective to impart an acidic pH to the composition; optionally, when the compositions of the invention comprise more than 1% wt. of a cationic surfactant, and/or when the compositions of the invention comprise one or more anionic, amphoteric or zwitterionic surfactants in amount of at least 0.01% wt, the compositions of the invention may include an amphiphilic solvent constituent; further optionally, one or more further constituents including coloring agents, fragrances and fragrance solubilizers, viscosity modifying agents including one or more thickeners, pH adjusting agents and pH buffers including organic and inorganic salts, optical brighteners, organic solvents, opacifying agents, hydrotropes, abrasives, and preservatives, as well as other optional constituents known to the art; and water in an amount of at least 80% wt, preferably in an amount of at least 85% wt. based on the total weight of the composition of which it forms a pan. wherein the composition exhibits self-induced movement when the composition is applied as a film or laminar layer onto a hard surface.
