Abstract
A synergistic antimicrobial composition having two components. The first component is a hydroxymethyl-substituted phosphorus compound. The second component is one of the following biocides: hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine, 2,6-dimethyl-1,3-dioxan-4-yl acetate or ortho-phenylphenol or its alkali metal or ammonium salts.
Claims7
A synergistic antimicrobial composition comprising:
- (a) a hydroxymethyl-substituted phosphorus compound selected from the group consisting of tetrakis(hydroxymethyl)phoshponium salts and tris(hydroxymethyl)phosphine;
- and (b) a second biocide selected from the group consisting of (i) hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine;
- (ii) 2,6-dimethyl-1,3-dioxan-4-yl acetate;
- and (iii) ortho-phenylphenol or its alkali metal or ammonium salts;
- wherein a weight ratio of the hydroxymethyl-substituted phosphorus compound to hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine is from 15:1 to 1:15, a weight ratio of the hydroxymethyl-substituted phosphorus compound to 2,6-dimethyl-1,3-dioxan-4-yl acetate is from 15:1 to 1:15, and a weight ratio of the hydroxymethyl-substituted phosphorus compound to ortho-phenylphenol or its alkali metal or ammonium salts is from 15:1 to 1:5.
