Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
187 words
A pressurized container having a discharge valve and charged with a self-propelling composition, said composition being separated in two phases when said container is allowed to stand, forming a stable homogeneous emulsion of said two phases in said container when said container is shaken and being dispensed in an aerosol mist form when said discharge valve is opened, said composition consisting essentially of A. 15 to 80 wt.% of a liquid propellant effective for discharging an aerosol of said composition when said discharge valve is opened and B. 85 to 20 wt.% of a liquid consisting essentially of i. 30 to 80 wt.%, based on the weight of B, of an alkanol having one to 3 carbon atoms, ii. 0.05 to 1.0 wt.%, based on the weight of B, of an emulsifier consisting of an adduct of 1 to 300 moles of ethylene oxide to a substance selected from the group consisting of castor oil, hydrogenated castor oil and lanolin, iii. 0.01 to 20 wt.%, based on the weight of B, of an active component or a mixture of active components and iv. the balance is water.
