  • What is dimethyl phthalate (DMP) concentration?
  • Dimethyl phthalate (DMP) concentration (presented as cumulative amount ug/cm²) in receptor phase over time (h) during permeation experiments with: a—Strat-M® membrane (SMM), b—in vitro epidermal model (Reconstructed Human Epidermis, RHE) and c – ex vivo human skin (HS).
  • What is the difference between diethyl phthalate and DMP?
  • Compared with diethyl phthalate (DEP), DMP is considered to be slowly absorbed via the skin membrane. Dermal absorption of DMP through rat skin is about 10–20 times higher than through human skin (410 vs 39.5 µg/cm 2 /hr) (NICNAS 2014).
  • What are the optimum conditions for dimethyl phthalate removal from water?
  • This study investigates the degradation of dimethyl phthalate (DMP) with hydrogen peroxide and ferrate (Fe (VI)) under various reaction conditions. The results showed that the optimum conditions for dimethyl phthalate removal from water were as follows: (a) pH 7.0 and (b) the original molar ratio of [Fe (VI)]/ [H 2 O 2 ]/ [DMP] equal to 10:2:1.
  • What is the concentration of DMP in household products?
  • Concentrations of DMP in domestic detergents, cosmetics, perfumes and personal care products are highly variable and range from 0.00004 % to 34 % (in combination with its analogue diethyl phthalate (DEP)).
  • Is dimethyl phthalate recalcitrant to biodegradation?
  • Dimethyl phthalate (DMP) ester is a common short-chained ester, which has been detected in many natural environments including marine waters, water courses, and sediments. (2) DMP is relatively recalcitrant to biodegradation in the natural environment because of its benzene carboxylic group and its hydrolysis half-life of about 3 years.
  • Is DMP phthalate toxic?
  • Due to the toxicological properties of DMP (low acute toxicity, low skin and eye irritation, low skin sensitizing potential), the occurrence, among consumers, of adverse acute effects resulting from use of cosmetics containing this phthalate is relatively low.
