Problems solved by technology

However, isothiazolinone compositions containing large amounts of divalent metal salts such as magnesium oxide are preferably not used in fungicides because it will present problems due to "salt clusters" of divalent metal salts

Embodiment 1-13 and comparative Embodiment 1

[0083] The concentrated solution of 3-isothiazolinone was prepared, and its composition and content are shown in Table 1. As the 3-isothiazolinone compound, use 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazoline in a mixing ratio of about 3:1 - Mixture of 3-ketones (MI).

[0084] As shown in Table 1, the samples of Examples 1-13 and Comparative Example 1 were prepared by the following method: 3-isothiazolinone compound, sodium nitrate, sodium carbonate, magnesium nitrate (comparative example), oxidation Magnesium (comparative example) was mixed with water and KIO was added to prevent precipitation 3 , NaBrO 3 and NaClO 2 .

Abstract

The present invention relates to an isothiazolone composition and a method for stabilizing the same, and particularly to an isothiazolone composition that does not comprise alkali earth metal salt of a divalent metal such as magnesium chloride, which causes salt shock, and thus that can be stably used as a sterilizer in a dispersion or emulsion such as paint acrylate or latex, therefore effectively preventing growth of microorganisms, and that has superior storage stability due to its low precipitation formation rate because it comprises a precipitation-preventing agent, and a method for stabilizing the same.

Description

Background of the invention [0001] (a) Field of Invention [0002] This invention relates to isothiazolone compositions and methods of stabilizing isothiazolones. In particular, the present invention relates to an isothiazolinone composition which does not contain divalent alkaline earth metal salts such as magnesium chloride which can cause salt clusters, and thus can be used stably in dispersions or emulsions such as acrylate paints or latex, etc. As a bactericide, it can effectively prevent the growth of microorganisms, because the composition has a low rate of sediment formation, and therefore has excellent storage stability. [0003] (b) Description of related technologies [0004] Isothiazolinones have broad-spectrum bactericidal activity against many harmful organisms derived from animals and plants, such as bacteria, molds, and algae. Adding them to cosmetics, paints, etc. as inhibitors can inhibit the growth of harmful microorganisms. [0005] However, because isot...
