  • Why is there a need for a DINP rule?
  • The need for a DINP rule arises because it will help increase public awareness of how DINP is being used and if it is being released into the environment. DINP, a common chemical name for a family of di-ester phthalates, is widely used as plasticizers. These chemicals are colorless, oily liquids with high boiling points, low volatilities, and poor solubility in water.
  • Which uses of DINP are excluded from TSCA?
  • There are other uses of DINP that are generally excluded from TSCA, such as personal care products, cosmetics, and food contact materials, and EPA did not evaluate risk associated with these uses. Workers may be exposed to DINP when making products containing DINP or otherwise using DINP in the workplace.
  • Does EPA need a peer review of the DINP human health hazard assessment?
  • EPA released the draft risk evaluation for DIDP in May 2024 and requested peer review on the DINP human health hazard assessment at that time. The Science Advisory Committee on Chemicals (SACC) is currently engaged in peer review of these documents.
  • How many uses contribute to the unreasonable risk of DINP?
  • In the draft risk evaluation, EPA preliminarily determined that two industrial uses and one consumer use significantly contribute to the unreasonable risk of DINP out of the 45 uses evaluated.
  • What is DINP used for?
  • DINP is a common chemical name for the category of chemicals that includes the following substances: 1,2-benzenedicarboxylic acid, 1,2-isononyl ester and 1,2-benzenedicarboxylic acid, and di-C9-11-branched alkyl esters, C9-rich. The primary use for DINP is as a plasticizer in plastic and rubber products.
  • Does DINP pose a risk to human health?
  • Past assessments, including the U.S. Consumer Product Safety Commission's (CPSC) risk assessment found that DINP exposure comes primarily from diet for women, infants, toddlers, and children. It is possible that DINP could pose risks to human health through uses or exposure pathways that are not regulated under TSCA.
