Abstract
The present invention relates to a water-repellant composition consisting essentially of at least one hydrophobic agent and at least one solvent which is compatible with the at least one hydrophobic active agent, this solvent being other than a fluorinated hydrocarbon, wherein the solvent is organic compound comprising at least one oxygen-comprising functional group and in that the hydrophobic active agent is a compound of an organopolysiloxane of formula (I): where P is an integer ranging from 0 to 150 and each R independently represents an alkyl or alkoxy group with 1 to 10 carbon atoms, a cycloalkyl group with 3 to 10 carbon atoms, a phenyl group, an aminated group, a halogen or a hydrogen, with the condition that at least one R is an aminated group.
