ABSTRACT:
A liquid concentrate comprises between about 4 and about 10 wt % of an isothiazolinone compound or mixture of isothiazolinone compounds, between about 25 and about 92 wt % of a plasticizer in which said isothiazolinone compound is soluble and between about 4 and about 50 wt % of 2,4,4'-trichloro-2'-hydroxydiphenyl ether. The 2,4,4'-trichloro-2'-hydroxydiphenyl ether stabilizes the concentrate against crystallization and/or freezing at sub-freezing conditions, particularly when the isothiazolinone compound has a melting point of 30.degree. C. or above. 2,4,4'-trichloro-2'-hydroxydiphenyl ether also enhances the anti-microbial properties of an isothiazolinone-containing concentrate.
