Embodiment Construction

[0008] The following is a detailed description of the present invention.

[0009] As used herein, the following terms have the assigned definitions unless the context clearly dictates otherwise.

[0010] The term "antimicrobial compound" refers to a compound capable of inhibiting or controlling the growth of microorganisms; antimicrobial compounds include bactericides, bacteriostats, fungicidal agents, depending on the dosage level applied, system conditions and the level of microbial control desired agents, fungistatic agents, algaecides and algaecides. Such term "antimicrobial compound" as used herein is synonymous with the term "biocide".

[0011] The term "microorganism" includes, for example, fungi (eg, yeast and molds), bacteria, and algae.

[0012] The following abbreviations are used throughout this specification: ppm = parts per million by weight (weight / weight), mL = milliliters, ATCC = American Type Culture Collection, SAG = University of Göttingen algal culture ...

Abstract

A synergistic antimicrobial composition containing zoxamide and one of 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one or 2-n-octyl-4-isothiazolin-3-one is provided. Also provided is a method of inhibiting the growth of or controlling the growth of microorganisms in a building material by adding such a synergistic antimicrobial composition. Also provided is a coating composition containing such a synergistic antimicrobial composition, and a dry film made from such a coating composition.

Description

technical field [0001] The present invention relates to combinations of antimicrobial compounds and their use in dry film protection applications that are unexpectedly more active than expected when using two individual antimicrobial compounds. Background technique [0002] Using a combination of at least two antimicrobial compounds can broaden the potential market, reduce usage concentrations and costs, and reduce waste. In some cases, commercial antimicrobial compounds fail to provide effective control of microorganisms even at high use concentrations due to weak activity against certain types of microorganisms, such as those resistant to some antimicrobial compounds. those microorganisms. Combinations of different antimicrobial compounds are sometimes used to provide overall control of microorganisms in a particular end-use environment. For example, WO1998 / 121962 discloses the combination of 3-iodo-2-propynyl butylcarbamate and pyridinethione, but this reference does no...
