Aqueous cleaning and surface treatment compositions for imparting oil and water repellency to treated surfaces which comprise: (a) fluoroaliphatic radical-containing poly(oxyalkylene) compound; (b) anti-resoiling composition; (c) anionic surfactant compound, preferably one or more selected from alkyl sulfates, alkyl benzene sulfates, and alkane sulfonates as well as salts thereof; (d) organic solvent; (e) citric acid salts, preferably one or more anhydrous and dihydrous sodium citrates; (f) water, wherein the compositions of the invention are at a neutral or alkaline pH, especially from about 8 to about 10. The compositions are particularly shelf stable, and exhibit excellent shelf stability in pressurized aerosol containers.
L'invention concerne des compositions aqueuses de traitement de surface et de nettoyage conférant déperlance et oléophobie à des surfaces traitées. Ces compositions comprennent: (a) un composé poly(oxyalkylène) contenant des radicaux fluoroaliphatiques; (b) des compositions anti-resalissures; (c) un composé tensioactif anionique, de préférence un ou plusieurs, sélectionné parmi des alkyle sulfates, alkyle benzène sulfates et des alcane sulfonates ainsi que des sels de ceux-ci; (d) un solvant organique; (e) des sels d'acide citrique, de préférence un ou plusieurs citrates de sodium anhydres ou dihydratés; (f) de l'eau, celles-ci ayant un pH neutre ou alcalin, compris notamment entre environ 8 et environ 10. Ces compositions ont une longue durée de vie en général, et une longue durée de conservation dans des récipients aérosol sous-pression.
