A test method for the determination of dimethylformamide in protective glove materials is defined in the EN 16778 standard, which is a European standard. This test method is generally applicable to materials such as:
When analyzing dimethylformamide in protective gloves, the glove is cut into small pieces and extracted with methanol in a sealed bottle in an ultrasonic bath. A portion of the extract is analyzed by gas chromatography - mass spectrometry (GC-MS).
Dimethylformamide is a colorless, odorless, organic compound and miscible with most organic liquids. It is a commonly used solvent for chemical reactions. This compound is a derivative of formamide, the amide of formic acid. It is a polar (hydrophilic) solvent with a high boiling point.
As a solvent with a low evaporation rate, dimethylformamide is used in the production of acrylic fibers and plastics. It is also used as a solvent in peptide coupling for pharmaceuticals, in the development and manufacture of pesticides, and in the manufacture of adhesives, synthetic leathers, fibers, films and surface coatings.
Dimethylformamide is used as a solvent in various applications in the chemical industry, as well as in the production process of gloves made of polyurethane and its derivatives. However, this compound is a chemical that is inhaled or absorbed through the skin during use. Therefore, it is classified as harmful. Prolonged or repeated exposure has adverse effects on the liver. Exposure limits have been defined in many countries and represent the maximum concentration in air for which gloves made of polyurethane are compatible.
Polyurethane coated protective gloves may contain dimethylformamide production residues. To avoid unnecessary exposure to the dimethylformamide compound, protective gloves should not contain more than 10 mg of dimethylformamide per kilogram of glove material. Monitoring this preventive health measure requires a sensitive analytical testing method. The test method defined in the EN 16778 standard is based on solvent extraction and uses methanol as a solvent.
