Abstract
Description
It is known to remove stains and spots from textiles by the use of so-called "dry cleaning " sprays in which a non-aqueous medium is sprayed on the textile from an aerosol dispenser using a propellant to force the cleaning medium from the dispenser. The liquid medium may contain an absorbent solid. Halogenated hydrocarbons have been used as the cleaning fluid. Halogenated hydrocarbons have also been used as aerosol propellants. Such halogenated hydrocarbons are no longer acceptable in products released to the atmosphere because of their adverse effect on the ozone layer. Hydrocarbon propellants, e.g. propane or butane, have been used in place of halogenated hydrocarbons and hydrocarbon solvents have been used as the cleaning liquid. However the use of these hydrocarbons introduces a fire hazard because of their flammability. It should be noted that the hydrocarbon solvents, although less volatile than the propellant, must be sufficiently volatile to evaporate readily from the surfaces on to which they are sprayed. There is also a problem of the generation of static electricity if the aerosol canister is punctured and thus releases the contents. A spark may be produced which may ignite the hydrocarbons.
the composition comprises a water-in-oil microemulsion in an amount from 5% to 50% by weight of the total composition including propellant, said composition containing from 2.5 % to 25. % by weight of water based on weight of the total composition including propellant.
