(WO9205229-A)      Two-phase system for delivering an aerosol from a pressurised container has propellant reservoiring effect and comprises 75-98 wt.% of an aq. component (I) and 25-2 wt.% of a propellant component (II).(I) comprises a mixt. of a non-ionic surfactant, a 9-18C prim. alcohol, a cpd. which is a polyhydroxy alcohol and/or ester, and an active ingredient, the balance being water. (II) comprises a 3-5C linear hydrocarbon. Pref. (I) comprises a mixt. of 0.25-6.5% of a fatty acid alkanolamide surfactant, 0.01-3.5% of a C11 prim. alcohol, 0.1-6% of glycerol and 0.01-20% of an organic active ingredient, the rest being water, and (II) comprises a mixt. of propane and butane.    USE/ADVANTAGE -   The system is effective in forming vesicles and dispensing the entire contents of the container whilst utilising a lower level of propellant and volatile organic cpd. (voc) than previously possible. It may be used to form delivery systems for polishes, air fresheners, insecticides, cleaning prods. and dermal treatments    (JP6501201-W)      Two-phase system for delivering an aerosol from a pressurised container is characterised by a propellant reservoiring effect and comprises 75-98 wt.% of an aq. component (I) and 25-2 wt.% of a propellant component (II).
