A foam forming aerosol cleaning composition for carpets, rugs, and the like is provided. The dispensable composition includes: (a) about 0.1 % to 6 % of a foam forming surfactant; (b) about 0.5 % to 5 % of a non-volatile, hydrophobic organic solvent which has a water solubility of less than about 18 % at 25 ~C; (c) an effective amount of an emulsifier; (d) an effective amount of a propellant; and (e) the balance as water; where said surfactant and solvent admixing and interacting with said propellant so as to form an initial foam upon dispensing to collapse without abrasion into a fabric surface and said emulsifier emulsifies the solvent after the collapse. The composition can also include magnesium lauryl sulfate which facilitates the removal of greasy dirt, corrosion inhibitor, fragrance, and/or an oxidizing agent. Use of a hydrophobic solvent/surfactant blend in the composition produces a foam that readily penetrates into the fibers of the carpet and emulsify and dislodge the greasy soil particles.

L'invention concerne une composition de nettoyage en aérosol formant une mousse destinée aux moquettes, tapis et analogues. La composition distribuable comprend: (a) environ 0,1 à 6 % d'un tensioactif formant une mousse, (b) environ 0,5 à 5 % d'un solvant non volatile, hydrophobe, organique présentant une solubilité dans l'eau inférieure à environ 18 % à 25 ·C, (c) une quantité efficace d'un émulsifiant, (d) une quantité efficace d'un gaz propulseur et (e) le solde constitué d'eau. Ledit tensioactif et le solvant mélangés et en interaction avec ledit gaz propulseur forment une mousse initiale lors d'une distribution, destinée à pénétrer sans abrasion dans la surface du tissu, ledit émulsifiant émulsionnant le solvant après la pénétration. La composition peut également comporter du magnésium lauryle sulfate facilitant l'élimination des tâches de graisse, un inhibiteur de corrosion, un parfum et/ou un agent d'oxydation. L'utilisation d'un mélange de solvants hydrophobes/tensioactifs dans la composition produit une mousse pénétrant facilement dans les fibres de la moquette, formant une émulsion et délogeant les particules de salissure de graisse.
