Abstract
A foaming cosmetic product is provided packaged in a non-aerosol mechanical dispenser. The dispenser includes a container for holding a liquid composition, a dispensing head with a housing enclosing a pump mechanism and a screen material in the flow path to convert liquid composition into a foam, and a diptube for delivering liquid from the container to the dispensing head. The cosmetic composition is an opaque creamy, relatively non-viscous fluid, the creamy appearance imparted by a latex with suspended polymer particles compatible with the foaming mechanism.
