Abstract
An aerosol foam cleaning composition for carpets and other soft-furnishings is provided. It has a volatile hydrocarbon propellant, a surfactant, a foam stabilizer polymer, a stain repellent fluorocarbon, an amine oxide foam booster, and water. The foam does not release hydrocarbon propellant at such a rate so as to create flammability problems, yet provides adequate residual stain repellent.
Claims11
An aqueous aerosol foam cleaning composition comprising from 2.5 to 3.5 weight percent of at least one volatile hydrocarbon propellant, the balance of the composition being a foam structure composition comprising by weight of the foam structure composition:
- (a) from 2.4 to 4.5 weight percent of at least one surfactant that is other than an amine oxide surfactant;
- (b) from 2.00 to 3.5 weight percent of at least one foam-stabilizer polymer;
- (c) from 0.1 to 0.2 weight percent of at least one stain-repellent fluorocompound;
- (d) from 0.25 to 0.5 weight percent of at least one amine oxide foam booster;
- and
- (e) water;
- wherein the proportions of said components provide a foam of anti-flammability, stability, and with a sufficient residual amount of stain repellant.
