Safety Conclusion

The conclusion for Fumaric Acid should be read as a CIR panel conclusion, not a regulatory limit. CIR assessments summarize expert-panel safety determinations for cosmetic use, while legal status still depends on the jurisdiction and product category.

On the basis of the data presented in this report, the CIR Expert Panel concluded that Fumaric Acid, Disodium Fumarate, Sodium Fumarate, Dibehenyl Fumarate, Di-C12-15 Alkyl Fumarate, Diethylhexyl Fumarate, Diisostearyl Fumarate, Sodium Stearyl Fumarate, and Ferrous Fumarate are safe as used in cosmetic formulations in the practices of use given in this Final safety assessment.

Formulation Reading

For formula review, begin with the exact INCI identity and the ingredient group covered by the CIR assessment. If the material is Fumaric Acid, the relevant comparison is whether the intended use aligns with the practices, concentration ranges, and conditions described in the CIR source.

The ingredient hub at Fumaric Acid should carry the substance-level profile. This page is the report-level summary, keeping the conclusion, ingredient scope, and use-context language attached to the CIR source rather than treating the conclusion as a universal permission.

Why This Page Exists
