Properties and stability
1. It has the ability to inhibit molds, bacteria, and yeasts. It has stronger sterilizing power against bacteria than molds. It has special effects on Staphylococcus and Streptococcus and is effective against Aerobacilli. The inhibitory content is 0.05%, but it is almost ineffective against Pseudomonas. The complete inhibitory content against Aspergillus niger is 0.3%, and against Penicillium chrysanthemum 0.1%. The inhibitory ability against Aspergillus flavus is poor.
Storage method
Store in a cool and dry place.
Synthesis method
1. Reaction of 3,5-Dimethylphenol and dichlorosulfonyl It can also be obtained by reacting 3,5-dimethylphenol with chlorine through zinc catalysis.
Purpose
1. Used as antifungal preservative in emulsions, cosmetics, leather, ink, plywood, etc., and commonly used as skin disinfectant in medicine.
