Bronopol fungicide introduction

Bronopol biocide with Chemical name of 2-Bromo-2-nitro-1,3-propanediol does not belong to the "formaldehyde release" fungicide. Bronopol at a concentration of 25ppm can effectively kill bacteria, Multi-bacterial mechanism, broad-spectrum killing of Gram-positive bacteria, Gram-negative bacteria, yeasts, molds commonly found in the environment.

A suitable pH range, it's effective in the range of pH Bronopol is a class of high-efficiency, broad-spectrum preservatives with the following distinct advantages:

4~9, that is, in the environment of weak acidity, neutrality and partial alkali, it can maintain strong antibacterial effect after adding.

It has special control effect on pseudomonas bacteria commonly found in water, and is a powerful supplement to KATHON preservatives. And Bronopol has been widely used in the preservation of washing industry products.

In some cases, bronopol releases a small amount of formaldehyde due to hydrolysis, but the amount of formaldehyde released in Bronopol is much lower than the dose required for bactericidal action. Therefore, Bronopol is not really meaningful Preservatives for "formaldehyde release". The United States and the relevant EU regulations have reached an agreement on this. As early as the EU Working Group meeting in January 2007, all participants reached a consensus that Bronopol's bactericidal ability is independent of formaldehyde, which relies mainly on the Bronopol molecule itself and the thiol group in the microbial cell structure. The group interaction is related to the formation of oxygen free radical sterilization. According to this mechanism of action, Bronopol is not a "formaldehyde-releasing body" fungicide.

Does the trace amount of formaldehyde produced by Bronopol affect product safety due to hydrolysis?

In fact, formaldehyde exists in humans and in a large number of common foods. The hydrolysis of Bronopol to form less than 1 ppm of formaldehyde is lower than the formaldehyde content of these common foods. At the same time, China's "Hygienic Standards for Cosmetics (2007)" stipulates that Bronopol's limited preservatives for cosmetics (the amount of additives should be less than 0.1%, while avoiding the formation of nitrosamines), also proved that under the correct use conditions Bronopol is used for the safety of liquid laundry products.
