LIQUID COMPOSITION FOR CLEANING SUFACES AND FOR PROVIDING HYDROPHOBIC COATING FILM THEREON

摘要

The invention relates to a liquid composition for cleaning hard surfaces comprising: a carrier, at least some of which is aqueous; one or more surfactants; and an effective amount of a compound of formula (I) wherein m and n, equal or different, are integers from 2 to 8 and R is an optionally substituted alkyl chain having from 8 to 18 carbon atoms, for providing a hydrophobic coating film on said hard surfaces. The invention also relates to a liquid composition for coating a substrate and for providing a hydrophobic coating film thereon comprising: a liquid carrier and an effective amount of a compound of formula (I). The liquid composition of the invention is effective for rendering self-cleaning said hard surface and for reducing the presence of water marks on said hard surface, even after said hard surface has been later subjected to aqueous contacts. Another aspect of the invention includes a hydrophobic coating film for at least partially covering a substrate, said hydrophobic coating film comprising a compound of formula (I).
