  • How is diisononyl phthalate (DINP) measured?
  • This method allows the simultaneous determination of gaseous and particulate diisononyl phthalate (DINP) occurring in the workplace air. A flow‐regulated pump is used for sampling by drawing ambient air through a sampling system consisting of a cellulose acetate filter and three silica gel tubes connected downstream.
  • What is diisononyl phthalate (DINP)?
  • Policies and ethics Diisononyl phthalate (DINP) is one of the widely used dialkyl phthalate (DAPs) softeners in the production of flexible polyvinyl chloride (PVC) plastics, copolymers, and resins. These phthalate plasticizers are incorporated into the PVC polymer matrix to impart...
  • How is diisononyl phthalate determined?
  • After sampling is complete, the filter and silica gel are desorbed with isopropanol (containing diethyl phthalate as an internal standard) and the content of diisononyl phthalate is determined by means of gas chromatography with a flame ionization detector (FID).
  • Is diisononyl phthalate a hazard?
  • Babich MA (1998) Preliminary hazard assessment of diisononyl phthalate (DINP) in children’s products. U.S. Consumer Product Safety Commission, Washington, DC. Babich MA, Chen S-B, Greene MA (1998) The risk of chronic toxicity associated with exposure to diisononyl phthalate (DINP) in children’s products.
  • What phthalate is present in the workplace air?
  • Long-chain phthalates such as diisononyl phthalate, di-n-decyl phthalate, diisodecyl phthalate, diundecyl phthalate and didodecyl phthalate present in the workplace air in the gaseous and particulate state can be simultaneously determined in a concen-tration range of 0.70 to 14.0 mg/m3 with this analysis method.
  • Is diisononyl phthalate soluble in water?
  • Diisononyl phthalate is an almost colourless, clear, water-insoluble liquid (boiling point approx. 270 °C (13 mbar), molar mass 418.6 g/mol). It is soluble in com-monly used organic solvents. DINP is one of the most commonly used plasticisers for PVC; 95% of the total amount of DINP is used as a plasticiser in PVC produc-tion.
