C.I. Disperse Yellow 3 (Cancer)
C.I. Disperse Yellow 3 is listed under California Proposition 65 for the Cancer endpoint. Its established safe harbor level is 80 µg/day as a NSRL, determined for exposure primarily via the ingestion route. CAS registry number: 2832-40-8.

What this level means
A NSRL is a daily exposure level for C.I. Disperse Yellow 3 that — at or below 80 µg/day per day — does not require a Proposition 65 warning because it poses no significant risk for the Cancer endpoint. This is the No Significant Risk Level (NSRL) — the daily intake for the cancer endpoint.
- Level: 80 µg/day per day (NSRL).
- Endpoint: Cancer.
- Route: exposure is assessed primarily through the ingestion route.
- CAS: 2832-40-8.
Businesses that expose consumers to more than the safe harbor level for C.I. Disperse Yellow 3 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 NSRL of 80 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.
