Embodiment 1

[0036] Embodiment 1. Dimethicone alkyl / Evaluation of oxazolidine in paint

[0037] In this example, 2,6-dimethyl-dimethyl-m-dioxan-4-ol (DMX) was evaluated in a commercial (inside eggshell) water-based latex paint formulation (pH 7.4) , 4,4-Dimethyl Oxazolidine (DMO), 7-Ethyl-bicyclo Antimicrobial profiles of oxazolidine (EBCO) and combination DMX / DMO, combination DMX / EBCO. Before commencing evaluation of preservative efficacy, ensure that the paint formulation is free of microbial contaminants.

[0038] Construction of experiments. For all evaluations, tests were performed in a 96-deep well block format using a total sample volume of 600 μl. In these samples, no more than 10% of the total volume consisted of biocides and biological solutions, all non-matrix additions were normalized for all samples. The 96-well block for each experiment contained biocide treated samples and no biocide control samples.

Embodiment 2

[0055] Example 2. Dimethicone alkyl / Evaluation of oxazolidine in spinning finish emulsion

[0056] In this example, 2,6-dimethyl-dimethyl-m-dioxan-4-ol (DMX), 4,4-dimethyl Oxazolidine (DMO), 1-(3-Chloroallyl)-3,5,7-Triaza-1-nitrogen Antimicrobial profiles of adamantane chloride (CTAC), 2-hydroxymethyl-2-nitro-1,3-propanediol (TN), and combinations of DMX / DMO, DMX / CTAC, and DMX / TN . Before commencing evaluation of preservative efficacy, ensure that the spin finish emulsion is free of microbial contamination. A spin finish emulsion was prepared by adding 1 part spin finish oil to 9 parts distilled water followed by stirring for 30 minutes.

[0057] Construction of experiments. For all evaluations, tests were performed in a 96-deep well block format using a total sample volume of 300 to 600 μl. In these samples, no more than 10% of the total volume consisted of biocides and biological solutions, all non-matrix additions were normalized for all samples. The 96-well blo...

Abstract

Provided are compositions comprising 2,6-dimethyl-m-dioxane-4-ol acetate and a biocidal compound selected from the groups consisting of: a biocidal oxazolidine; 1-(3- chloroallyl)-3,5,7-triaza-1-azoniaadamantane; and tris(hydroxymethyl)-nitromethane. The compositions are useful for controlling microorganisms in aqueous systems.

Description

technical field [0001] This invention relates to biocidal compositions and their use in aqueous systems and methods of controlling microorganisms in aqueous systems. The composition includes 2,6-dimethyl-m-dioxan-4-ol and a second biocide. Background technique [0002] Water-based materials generally require protection from undergoing microbial degradation and / or damage during shelf life and use. Preservatives are used to control microbial degradation and / or damage in aqueous materials, however, sometimes they do not provide effective control of a broad spectrum of microorganisms, even when used in high concentrations. Furthermore, preservatives are often expensive components of the product. Although combinations of different biocides are sometimes used to provide overall control of microorganisms in a particular end-use environment, there remains a need for other combinations of biocides with increased activity against various species of microorganisms. Combinations that...
