Kettering, UK - Footwear and furniture test group SATRA Technology Centre says a recent European ban on the biocide dimethylfumarate is causing some confusion, as the abbreviation for the chemical, DMF, is also used for dimethylformamide a solvent used in the manufacture of polyurethanes.
An EU directive (2009/251/EC) has restricted import of products that contain dimethylfumarate.
A statement from Kettering, UK-based SATRA points out that dimethylfumarate is a biocide used to prevent mould growth on products during transit or storage. "It is often supplied in the form of a permeable paper sachet through which the chemical will be released. Dimethylfumarate is recognised as a potential skin irritant and has been implicated in cases of contact dermatitis from furniture and footwear in several EU countries," SATRA said.
SATRA can test materials for the presence of dimethylfumarate, and assist in looking at other restricted substances.
Dimethylformamide is not banned, but since it is harmful by inhalation it has workplace exposure limits (WELs) for use in manufacture, SATRA points out.
