Aerosol foam marking compositions

The aerosol composition of claim 2, wherein said liquid propellant comprises at least one hydrocarbon propellant.

The aerosol composition of claim 3, wherein said propellant is present in an amount ranging from about 5 to about 40 wt. percent of said composition.

An aerosol composition which provides a foam upon discharge from a suitable containment means, said composition comprising (a) a liquid propellant in an amount ranging from about 10 to about 30 wt. percent of the composition, (b) water, (c) a water-insoluble acrylic polymer present in an amount ranging from about 2 to about 15 wt. percent of the composition, (d) a surfactant present in an amount ranging from about 0.1 to about 15 wt. percent of the composition which stabilizes the foam produced upon discharge of the composition from said containment means yet allows the foam to become unstable and collapse upon exposure to water, (e) a foam stabilizing agent present in an amount ranging from about 0.05 to about 10 wt. percent of the composition, and (f) a solvent which solvates said foam stabilizing agent present in an amount ranging from about 3 to about 15 wt. percent of the composition. a thickener.

An aerosol composition adapted for providing a foam upon discharge from a suitable containment means, said composition comprising (a) a liquid propellant selected from the group consisting of methane, ethane, propane, butane, and mixtures thereof present in an amount ranging from about 18 to about 22 wt. percent of the composition, (b) water, (c) a water-insoluble acrylic polymer comprising a copolymer of styrene, acrylonitrile, and an acrylic ester present in an amount ranging from about 5 to about 15 wt. percent of the composition, (d) a surfactant selected from the group consisting of lauryl sulfate, lauryl ether sulfate, and mixtures thereof;

• and mixtures thereof present in an amount ranging from about 1 to about 5 wt. percent of the composition, (e) a foam stabilizing agent selected from the group consisting of cetyl alcohol, stearyl alcohol, and mixtures thereof present in an amount ranging from about 0.5 to about 3 wt. percent of the composition, and (f) a solvent adapted for solvating said foam stabilizing agent selected from the group consisting of ethylene glycol monomethyl ether, propylene glycol monomethyl ether, and mixtures thereof present in an amount ranging from about 8 to about 10 wt. percent of the composition.
