Abstract

An aerosol product comprises a foaming concentrate composition that comprises a surfactant and particulate material having a particle size of at least about 100 μm. The foaming concentrate composition and propellant are contained in a package comprising a container and a powder valve comprising an orifice having an orifice diameter of at least about 660 μm. Preferably, a ratio of the maximum particle size of the particulate material to the orifice diameter of the orifice is less than about 0.75.

Claims

1. An aerosol product comprising:

(a) a foaming concentrate composition comprising;

(i) a surfactant; and

(ii) from about 0.1% to about 10%, by weight of said foaming concentrate composition, of particulate material;

wherein said foaming concentrate composition comprises at least about 0.1%, by weight of said foaming concentrate composition, of particulate material having a particle size of at least about 150 μ

m;

(b) a propellant; and

(c) a package containing said foaming concentrate composition and said propellant;

wherein said package comprises a container and a powder valve comprising a valve stem;

wherein said valve stem comprises an orifice having an orifice diameter of at least about 660 μ

m;

wherein said orifice is sealed when said valve is in a closed position.
