Water repellent composition and windscreen washer comprising a siloxane, ether alcohol, and cationic surfactant

   
   

The water-repellent composition, in particular for a windscreen washer liquid, comprises a compound of organopolysiloxane type as hydrophobic active agent and a solvent. According to the invention, the composition is used in combination with a solubilizing mixture comprising: at least one ether alcohol, as third solvent, one nonionic silicone surfactant and one cationic surfactant.

La composition hydrofuge, en particulier pour un liquide de rondelle de pare-brise, comporte un composé du type d'organopolysiloxane comme agent actif hydrophobe et dissolvant. Selon l'invention, la composition est employée en combination avec une comportement de solubilisation de mélange : au moins un alcool d'éther, en tant que troisièmement le dissolvant, un agent tensio-actif non ionique de silicone et un agent tensio-actif cationique.
