Abstract
Antimicrobial composition comprising iodide and thiocyanate anions, periodic acid, and nitrogen and/or phosphorous containing polymers.
Claims35
An antimicrobial composition comprising
- (1) a mixture of iodide anions and thiocyanate anions,
- (2) periodic acid or a salt thereof, and
- (3) at least one copolymer comprising as units
- (a) 5 to 100% by weight of at least one monoethylenically unsaturated monomer comprising nitrogen and/or phosphorous containing groups,
- (b) 0 to 95% by weight of at least one monoethylenically unsaturated comonomer comprising acidic groups,
- (c) 0 to 75% by weight of at least one further comonomer, and
- (d) 0 to 5% by weight of crosslinking comonomers and
- wherein there are at least two different units of (a).
