Assignee:

Vitec Speciality Chemicals Limited - London

International Classification:

C11D 3/48
C11D 1/645
C11D 3/43

US Classification:

Abstract:

The present invention relates to water-stable compositions and compounds formed by mixing an organosilane, optionally having a non-hydrolyzable organic group, but having one or more hydrolyzable groups, and an acidified stabilizing solution prepared from at least one acid, at least one glycol ether, and at least one cationic surfactant, preferably at least one quaternary ammonium salt (QAS), in water. The present invention also relates to methods of treating a substrate by mixing or contacting the substrate with the product, compound, or composition of this invention for a period of time sufficient for treatment of the substrate, methods of antimicrobially treating a food article, methods of antimicrobially coating a fluid container, methods of dyeing and treating a substrate, and methods of antimicrobially coating a latex medical article. The invention also pertains to a treated substrate having adhered thereto the product, compound, or composition of this invention.

William Crook - Isle of Wight, GB

Assignee:

Vitec Speciality Chemicals Limited - London

International Classification:

A01N 55/00
A01N 25/34
A01N 25/28

US Classification:

514 63, 424411, 424417, 424421

Abstract:

The present invention relates to methods for diluting water-stable organosilane compositions comprising an organosilane, optionally having a non-hydrolyzable organic group, but having one or more hydrolyzable groups, and an acidified stabilizing solution prepared from at least one acid, and at least one cationic surfactant, preferably at least one quaternary ammonium salt (QAS), in water. The organosilane composition is diluted with a glycol ether. The resultant diluted organosilane composition may be used to antimicrobially treat a substrate.

US Classification:

427314, 427384, 514 63

Abstract:

The present invention relates to water-stable compositions formed by mixing an organosilane, optionally having a non-hydrolyzable organic group, but having one or more hydrolyzable groups, and an acidified stabilizing solution prepared from at least one acid, and at least one cationic surfactant, preferably at least one quaternary ammonium salt (QAS), in water.
