DMF Testing

BLC offers Dimethyl fumarate testing DMF in product and specialises in DMF in leather, footwear, product or anti mould sachets which can be conducted within 5 days or less.

DMF testing in product. BLC have experience extracting Dimethyl fumarate DMF from leather and other materials. BLC has developed a method for detection of dimethylfumarate DMF and other fungicides with a reliable detection limit of less than 0.1mg/kg. BLC advises that immediate due diligence testing of products or parts of products, such as materials prone to mould growth, packaging and silica gel sachets, be carried out.

Dimethyl Fumarate DMF – Properties
Dimethylfumarate, also known as DMF, has good antifungal properties, and has been associated with mould inhibitor sachets used in finished footwear and furniture. Recently, DMF has been highlighted as being an allergenic sensitizer causing eczema at low concentrations

Dimethyl fumarate is a methyl ester of fumaric acid, with a chemical structure of C₆H₈O_4.This white crystalline solid is a chemical with preservative properties that diminish over time.

Dimethylfumarate DMF has good antifungal properties, and as such has been used as a mould inhibitor within sachets in finished leather products. Like all living organisms, moulds need certain basic requirements to grow and multiply; a source of moisture and a source of nutrients. In wet blue leather the source of moisture is clear. In finished product the level of moisture is much lower and therefore the growth of mould is less. However, when transporting leather between different climates, or if the product is stored in an inappropriate manner, moisture build up in certain areas, such as inside packaging, can readily lead to the growth of mould. Many of the process chemicals used in the manufacture of leather can act as nutrients for mould growth, for example phosphates, surfactants and fatliquoring agents. DMF has been found in sachets placed within the furniture structure or inside the shoe box, often labelled as ‘anti-mould agent’. Its function is as a biocide to kill any mould that may arise from storage and transportation from hot and humid climates. In these environments, the volatile DMF in the sachet evaporates and can impregnate the leather. However, it has also been found to severely affect some consumers when they come into contact with these products.
