  • What is Di-isononyl phthalate (DINP)?
  • Di-isononyl phthalate (DINP) is a phthalate used as a plasticizer in e.g. many technical products. It exists in two forms (and two CAS numbers), reflecting the two possible routes for isononanol precursor production. However their properties are similar.
  • What is a CAS RN for diisononyl phthalate?
  • On May 23rd EPA received a manufacturer requested risk evaluation for diisononyl phthalate (DINP; CAS RN 28553-12-0 & 68515-48-0). This substance is represented by two CAS RNs (28553-12-0 & 68515-48-0) that reflect differences in how the chemical is manufactured.
  • How is Di-isononyl phthalate produced?
  • Di-isononyl phthalate is produced by one-step ester-ification of phthalic anhydride with isononanol (INA) and a catalyst. Two types of isononanol can be used for the synthesis: either a pure C9 fraction (synthe-sized from isooctene), or a C8-C10 fraction, C9-rich (synthesized from C7-C9, C8-rich alkene).
  • Which phthalates are used in plastic products?
  • DINP is one of the phthalates most frequently used in plastic products. Some polyvinyl chloride (PVC, vinyl) flooring, materials used in automobile interiors, wire and cable insulation, gloves, tubing, garden hoses, and shoes. DINP is also used in some non-PVC products, such as some inks and pigments, adhesives, sealants, paints and lacquers.
  • What are the properties of DINP Plastisol?
  • The main properties of DINP are low volatility and density. DINP displays good resistance to aging as well as easy plastisol coating, spraying and dipping. Further, it is also compatible with secondary plasti-cizers. Low volatility and density enables reduced process emissions and improved working conditions.
  • How much phthalate should a manufacturer report?
  • For chemicals such as di-isobutyl phthalate which are not subject to specific TSCA actions, a manufacturer is required to report any volume generally above 25,000 pounds, while small manufacturers are only required to report any volume generally above 100,000 pounds.
