Abstract

Provided is a biocidal composition comprising 2,6-dimethyl-m-dioxane-4-ol acetate and an isothiazolinone biocidal compound. The composition is useful for controlling microorganisms in aqueous or water containing systems.

First claim

What is claimed is:

1. A composition comprising:
2,6-dimethyl-m-dioxane-4-ol acetate; and
a mixture of 5-chloro-2-methyl-3-isothiazolinone and 2-methyl-3-isothiazolinone
wherein the weight ratio of 2,6-dimethyl-m-dioxane-4-ol acetate to the mixture of 5-chloro-2-methyl-3-isothiazolinone and 2-methyl-3-isothiazolinone is between 892:1 and 10:1.

2. A composition according to claim 1 further comprising one or more surfactants, ionic/nonionic polymers and scale, corrosion inhibitors, oxygen scavengers or additional biocides.

3. A method for controlling microorganisms in an aqueous or water containing system, the method comprising treating the system with a composition according to claim 1 .

4. A method according to claim 3 wherein the aqueous or water containing system is selected from the group consisting of paints and coatings; latexes; adhesives; inks; pigment dispersions; household and industrial cleaners; detergents; mineral slurries; polymer emulsions; metalworking fluids;
construction products; personal care products; textile fluids; industrial process water; oilfield functional fluids and fuels.

5. A method according to claim 4 wherein the aqueous or water containing system is selected from the group consisting of paints and detergents.

6. A method for controlling algae growth in a latex, the method comprising treating the latex with a composition comprising:
2,6-dimethyl-m-dioxane-4-ol acetate; and
a mixture of 5-chloro-2-methyl-3-isothiazolinone and 2-methyl-3-isothiazolinone.
