Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A synergistic antimicrobial composition comprising: (a) tetrakis(hydroxymethyl)phosphonium sulfate; and (b) a second biocide which is ortho-phenylphenol or its alkali metal or ammonium salts; wherein a weight ratio of tetrakis(hydroxymethyl)phosphonium sulfate to ortho-phenylphenol or its alkali metal or ammonium salts is from 9:1 to 3:1 or 2.25:1 to 1:2.25. 2. The composition of claim 1 in which the second biocide is a sodium salt of ortho-phenylphenol.
