Di(2-ethylhexyl)phthalate (DEHP) (Cancer & Reproductive)
Di(2-ethylhexyl)phthalate (DEHP) is listed under California Proposition 65 for the Cancer & Reproductive endpoint. Its established safe harbor level is 200 µg/day as a MADL, determined for exposure primarily via the ingestion route. CAS registry number: 117-81-7.

What this level means
A MADL is a daily exposure level for Di(2-ethylhexyl)phthalate (DEHP) that — at or below 200 µg/day per day — does not require a Proposition 65 warning because it poses no significant risk for the Cancer & Reproductive endpoint. This is the Maximum Allowable Dose Level (MADL) — the daily intake for the reproductive/developmental endpoint.
- Level: 200 µg/day per day (MADL).
- Endpoint: Cancer & Reproductive.
- Route: exposure is assessed primarily through the ingestion route.
- CAS: 117-81-7.
Businesses that expose consumers to more than the safe harbor level for Di(2-ethylhexyl)phthalate (DEHP) must provide a clear and reasonable Prop 65 warning. Compliance is assessed against the applicable OEHHA safe harbor level above; where no safe harbor level is established, an exposure assessment may be required.
Compliance notes
- Compare the daily exposure to the MADL of 200 µg/day.
- If exposure exceeds the level, a Prop 65 warning is generally required.
- Confirm the current OEHHA listing and any updates to the level before relying on it — safe harbor levels are amended periodically.
