Draft 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 required by Section 6(b) of the Toxic Substances Control Act (TSCA) and implementing regulations (40 CFR Part 702) (Docket ID: EPA-HQ-OPPT- 2018-0503).

Dibutyl Phthalate 84-74-2 Hazard Summary Dibutyl phthalate is used in making flexible plastics that are found in a variety of consumer products. It appears to have relatively low acute (short-term) and chronic (long-term) toxicity. No information is available regarding the effects in humans from inhalation or oral exposure to dibutyl phthalate
- When is dibutyl phthalate included in the iris database?
- Dibutyl phthalate; CASRN 84-74-2 Human health assessment information on a chemical substance is included in the IRIS database only after a comprehensive review of toxicity data, as outlined in the IRIS assessment development process.
- What is dibutyl phthalate?
- It has a role as an environmental contaminant, a teratogenic agent, a plasticiser, a metabolite and an EC 3.2.1.20 (alpha-glucosidase) inhibitor. It is a phthalate ester and a diester. It is functionally related to a butan-1-ol. Dibutyl phthalate is produced from n-butanol and phthalic anhydride in an ester formation reaction.
- Does dibutyl phthalate have health effects?
- The health effects data for dibutyl phthalate were reviewed by the U.S. EPA RfD/RfC Work Group and determined to be inadequate for derivation of an inhalation RfC. For additional information on health effects of this chemical interested parties are referred to the EPA documentation listed below. U.S. EPA. 1987.
- What is the LD50 of dibutyl phthalate?
- Acute oral LD50 for rats 8,000 mg/kg (RTECS, 1985). Dibutyl phthalate is included as an insect repellent in some aerosol sprays used to treat flystrike in sheep. It is colorless oily liquid with a very weak aromatic odor. Dibutyl phthalate occurs as an odorless, oily, colorless, or very slightly yellow-colored, viscous liquid.
- Does dibutyl phthalate cause fetal toxicity?
- I.A.4. Additional Studies/Comments (Oral RfD) Fetotoxicity was observed when mice were fed 2100 mg/kg/day dibutyl phthalate throughout gestation (Shiota and Nishimura, 1982). An increase in terata of borderline statistical significance was observed in progeny of this treatment group.
- Does dibutyl phthalate increase Terata?
- An increase in terata of borderline statistical significance was observed in progeny of this treatment group. Dibutyl phthalate produces degeneration of the seminiferous tubules, probably as a result of increased urinary excretion of zinc (Gangolli, 1982). I.A.5. Confidence in the Oral RfD
