Properties: white scaly crystal, slightly spicy taste, soluble in alcohol, ether, chloroform and other solvents, slightly soluble in water.

Ii. Mechanism of action: The bacteriostatic activity of dimethyl fumarate body for dimethyl fumarate molecular state, in the molecular state of dimethyl fumarate can smoothly through the microbial cell membrane, enters the cells, so as to exert its bacteriostasis, dimethyl fumarate effectively through contact and fumigation double way into a microbe, inhibition of microbial cell division, By inhibiting the enzyme activities of HMP and EMP in TCAC, microbial respiration was inhibited, so that the growth and reproduction of microorganisms could be effectively controlled.

Three, antibacterial spectrum and effect: it has special inhibitory effect on many molds and has anti-fungal ability. According to reports, the United States of dimethyl fumarate used for bread mildew test, in the same conditions stored bread not moldy period, add calcium propionate bread for 16-30 days, and add dimethyl fumarate bread for days, its efficacy is much better than calcium propionate. The Beijing Institute of Nutrition Sources, the Chinese Academy of Preventive Medicine and institutions in Hunan have carried out mildew prevention experiments on dimethyl fumarate in food, bread and grain. The results showed that dimethyl fumarate had significant inhibitory effect on eight kinds of fungi commonly found in food, such as Aspergillus flavus, Aspergillus Niger, penicillium penicillium, Alternaria alternaria, Terra-dendri candida and Fusarium glossum. The mildew proof agent used in feed is better than acid mildew proof agent such as propionate sorbic acid and benzoic acid. The anti-mildew effect of cosmetics is better than methyl paraben and propyl ester, and has no adverse effect on human skin. The volatile solution made of dimethyl fumarate was sprayed in wardrobe and bookcase, and good mildew proof effect was also obtained. In addition, dimethyl fumarate has been used in traditional Chinese medicine, textile, leather and other fields to obtain satisfactory results.

Four, features and uses: Is the United States developed in the 80 s a new fungicide, named "bad" the enemy, and has low toxicity (LD rat oral/kg) as high efficiency, broad spectrum antibacterial, security, good chemical stability, long duration, wide PH range of used, etc, can inhibit a variety of mold, yeast and bacteria, particularly of clostridium botulinum and yellow aspergillus has a good inhibitory effect. The antibacterial activity of dimethyl fumarate was not affected by PH value. And both insecticidal activity, but also has a touch and fumigation effect, widely used in food, beverage, feed, Chinese medicine, cosmetics, fish, meat, vegetables, fruits and other mildew, anti-corrosion, anti-insect, fresh.

Five, usage and dosage: this product can replace the current often used calcium propionate, sorbic acid, benzoic acid and other products, its freshness time up to 60-90 days, the amount of addition is -/kg. Vi. Others: The content of this product is 99.5%, packing specification: / barrel. Do not store in aluminum cans.
