DMP belongs to a group of phthalates used ubiquitously as solvents and plasticisers (plastic softeners) worldwide.  DMP is not manufactured in Australia, but imported mainly as solvents for the mining industry, and in the manufacture of various commercial and domestic products with a small proportion in children's toys, childcare articles and cosmetics.  Based on the assessment findings, NICNAS is not recommending any amendments to the existing regulatory controls in Australia for DMP.
