  • Who manufactures diethyl phthalate?
  • Thirumalai Chemicals is one of the leading manufacturers of Diethyl Phthalate. Industrial uses of DEP include plasticizers, detergent bases, aerosol sprays, and to bind cosmetics and fragrances.
  • What is diethyl phthalate (DEP)?
  • Diethyl phthalate (DEP) is a clear substance that is liquid at room temperature and is slightly denser than water with low volatility. It is synthetically produced and is commonly used to make plastics more flexible.
  • Is diethyl phthalate safe?
  • The only phthalate which still has some usage in cosmetic and personal care products is diethyl phthalate (DEP). The safety of DEP is well supported among the scientific community. Recognized scientific experts and governmental agencies have concluded repeatedly that DEP is safe for use in cosmetics and personal care products as currently used.
  • Is diethyl phthalate biodegradable?
  • Diethyl phthalate is likely to undergo biodegradation in the environment. However, abiotic degradation processes such as hydrolysis, oxidation, and photolysis are unlikely to play significant roles in the environmental fate of diethyl phthalate.
  • What is the purity of diethyl phthalate?
  • The reported purity of diethyl phthalate is between 99.70% and 99.97%. The main impurities are isophthalic acid, terephthalic acid, and maleic anhydride (Peakall 1975). The U.S. production volume of diethyl phthalate gradually declined from approximately 21 million pounds in 1980 to 19 million pounds in 1987 (USITC 1981, 1988).
  • How is diethyl phthalate measured in samples?
  • Diethyl phthalate can be measured in samples using gas chromatography (GC), combined with electron capture detection (ECD) or mass spectroscopy (MS). This method has been used to measure diethyl phthalate in human semen (Waliszewski and Szmczymski 1990), animal fat (van Lierop and van Veen 1988), and animal tissues (Giam and Chan 1976).
