Diethyl phthalate - inhalable fraction. Documentation of proposed values of occupational exposure limits (OELs)
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2015, Vol 31, Issue 4
Abstract
Diethyl phthalate (DEP) is a colorless, oily liquid. It is obtained in the reaction of phthalic acid with ethanol in the presence of concentrated sulfuric acid. Diethyl phthalate is used as a plasticizer in plastics, a solvent of cellulose acetate and nitrocellulose and a base of perfume in cosmetics and detergents. It is also used as a lubricant and a moisturizer in the production of packaging for food and pharmaceuticals.The exposure to diethyl phthalate occurs during its production and use. The exposure of the general population is associated with contact with products containing this compound (cosmetics, toys) and the consumption of contaminated food or water.According to GUS, in 2007, 2010 and 2011 there were no cases of exceedances of the existing norms for diethyl phthalate in workplace air (MAC-TWA 5 mg/m3, STEL 15 mg/m3). Available data from measurements taken in 5 provinces reported two people who in 2010 were exposed to diethyl phthalate concentrations in the range of 0.1 ÷ 0.5 of the MAC-TWA (NDS). According to the Classification of Activities (PKD) of the Polish Central Statistical Office (GUS) these persons were employed in education sector (section 85). The exposure of workers to diethyl phthalate at a concentration above 0.1 TWA values in these 5 provinces was not noticed in 2011.Skin irritation, sensitization, phototoxicity and photosensitization were not observed after application of diethyl phthalate to the human.
