COMPOSITIONS CONTAINING POLYORGANOSILOXANES WITH ANIONIC FUNCTIONALITY FOR HYDROPHOBIC MODIFICATION OF SURFACES AND IMPROVED TRANSPORTATION OF ACTIVE AGENTS TO SURFACE THUS TREATED Russian patent published in 2006 - IPC C08L83/04 C08L83/10 A61K6/93 

FIELD: polyorganosiloxane applications.

SUBSTANCE: compositions for treating and modifying surfaces contain siloxane polymers with functional side residues including two or more anionic groups, of which at least one being carboxyl group. Surface treated with such composition acquires hydrophobicity owing to deposited siloxane polymer with anionic functionality. The latter imparts a number of advantages to surface such as easiness of cleaning, removal of impurities, removal and prevention of spots, conditioning, and so forth. Moreover, siloxane polymer with anionic functionality acts as carrier when active agents are applied onto surface and improves retention and efficacy of active agents on treated surface.

EFFECT: enlarged assortment of surface-modification substances.
