COMPOSITION FOR DEMOISTENING SURFACES

摘要

Demoisturizing composition used for the displacement of liquid water, comprising a chlorofluorocarbon that is liquid at room temperature, containing a surface-active agent responding to the formula: in which R is an alkyl group in C6-C18 R' is an alkyl group in C1 to C2 R'' is an alkyl group in C1 to C18 p is a value ranging between 1 and 2 characterized in that the surface-active composition is prepared by mixing the following three constituents: (R''O)p(OH)2-pPO2H where RF represents a straight or branched perfluorinated alkyl chain of formula CqF2q+1 in which q is a whole number ranging between 2 and 20 and where X is a divalent bond group that may be partially halogenated and R1 and R2 represent a hydrogen atom, an alkyl radical or a hydroxyalkyl radical, containing less than 6 carbon atoms.
