LIQUID CLEANING COMPOSITION AND METHOD OF CLEANING A SURFACE

摘要

The invention relates to a liquid cleaning composition for hard surfaces comprising: - a carrier, at least some of which is aqueous; - one or more surfactants; - solid inorganic microparticles having a particle size of from 0.5 to 5 µm, a surface area of from 10 to 50 m2/g and a crystallinity degree CD lower than 50%, the crystallinity degree being defined as CD = (X/Y) 100 wherein: Y= diffracted peaks net area + background area, X = diffracted peaks net area of the microparticles X-ray diffraction pattern. The liquid cleaning composition of the invention allows to allows to reduce in a substantial way the abrasive action on the surface to be cleaned and to facilitate the rinsing operations while attaining at the same time a satisfactory cleaning action. Another aspect of the invention includes a method of cleaning a surface of an article and of imparting hydrophilic properties to the surface comprising the steps of applying to the surface a liquid cleaning composition as defined above and of rinsing the composition applied to the surface.
