Risk Evaluation for Dibutyl Phthalate (1,2-Benzene
Dibutyl phthalate (CASRN 84-74-2) is a colorless to faint yellow oily liquid. The primary use for dibutyl phthalate is as a plasticizer, in adhesives and sealants, and paints and coatings.
Final Scope of the Risk Evaluation for Dibutyl Phthalate (1,2
In December 2025, EPA designated dibutyl phthalate (CASRN 84-74-2) as a high-priority substance for risk evaluation following the prioritization process as required by Section 6(b) of the Toxic Substances Control Act (TSCA) and implementing regulations (40 CFR Part 702) (Docket ID: EPA-HQ-OPPT- 2025-0131).
