What is DMF?

In recent years, desiccant manufacturers have often been asked a question, that is: Does the desiccant contain DMF? Can it be used in import and export? Does it meet EU certification standards?  

So what is DMF? Should the desiccant contain DMF?

DMF is the abbreviation of "dimethyl fumarate", also known as (E) dimethyl 2-butenedioate, dimethyl fumarate, dimethyl allomaleate, commonly known as anti-mildew preservative Mysterious 1. It is white crystal or crystalline powder at room temperature.

Dimethyl fumarate (DMF) has the characteristics of low toxicity, high efficiency and antibacterial. It is mainly used for sterilization and anti-mildew in the production, storage and transportation of leather, footwear and textiles. Dimethyl fumarate (DMF) is much better than calcium propionate in preventing mildew in bread. According to domestic research, dimethyl fumarate (DMF) has good antifungal ability, and its antifungal effect on feed is better than that of acid preservatives such as propionate, sorbic acid and benzoic acid. It can completely inhibit many molds and bacteria in PDA medium containing 500-800 ppm. In addition, some factories also spray dimethyl fumarate (DMF) on products or packaging for sterilization and mildew prevention.

The picture comes from the Internet, if it is violated, it must be deleted.

However, dimethyl fumarate (DMF) is corrosive and allergenic to humans. According to clinical trials, dimethyl fumarate (DMF) can be inhaled through the esophagus, causing corrosive damage to the human intestine and internal organs and causing allergies; and when the substance comes into contact with the skin, it can cause contact dermatitis pain (including Itching, irritation, redness and burns); it will cause great harm to human health, especially to the growth and development of children.

On January 29, 2009, the European Union passed a draft resolution on "guaranteeing that consumer products containing dimethyl fumarate will not be placed on the European market", which came into effect on May 1, 2009. The draft clearly stipulates that if the content of dimethyl fumarate in consumer products or their parts exceeds 0.1 mg/kg, or if the product itself has declared its content of dimethyl fumarate, it will be identified as "containing dimethyl fumarate." methyl ester” products are prohibited from entering the EU market.

China banned the addition of dimethyl fumarate in food desiccants, and the "Notice on Printing and Distributing the List of Non-edible Substances that May Be Illegally Added in Foods (Second Batch)" (Food Regulation Office [2009] No. 5) will It is included in the list of illegally added non-edible substances, and a method for detecting dimethyl fumarate gas chromatography (the detection limit is 25 mg/kg) is specified. This method has the advantages of high analytical sensitivity and wide application range. It played a huge role in the "sniper battle" against dimethyl fumarate.

Topone's dried products do not contain dimethyl fumarate (DMF) and other harmful substances to human body, and comply with EU import and export standards. ) and the U.S. Environmental Protection Agency (EPA) certification and registration, the product quality fully complies with the latest European and American laws and regulations.
