Dimethylfumarate - DMFu

Dimethylfumarate, DMFu, CAS No：624-49-7.
DMFu is used for consumer products, such as leather furniture and footwear, to prevent moulds that may deteriorate leather furniture or footwear during storage or transport in a humid climate. DMFu is often used in desiccant sachets, which can be placed within the product or in its packaging.

DMFu penetrates through clothing, and can get onto consumers’ skin. Consumers exposed to DMFu have experienced health problems like dermatitis or allergies, with symptoms, such as skin itching, irritation, redness, burns, and respiratory difficulties.

On May 1, 2009, the EU Commission ban of the use of DMFu in consumer products came into effect. The EU Commission Decision requires Member States to ensure that consumer products sold in the European Union shall not contain more than 0.1 ppm (mg/kg) of DMFu. Products already on the market must be recalled and withdrawn without delay, and consumers have to be informed about the serious risk associated with excess levels of DMFu.

On May 16, 2012, in (EU) No 412/2012 DMFu was added into the annex XVII (entry 61) of REACH.
