Ingredients Reviewed

The review scope matters because CIR conclusions often apply to an ingredient family rather than a single INCI name. In this report, the ingredient list includes benzalkonium montmorillonite, benzalkonium sepiolite, hydrogenated tallowalkonium bentonite, quaternium-18/benzalkonium bentonite, quaternium-90 bentonite, quaternium-90 montmorillonite, quaternium-90 sepiolite, stearalkonium bentonite.

Safety Conclusion

The conclusion for benzalkonium montmorillonite 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.

For use levels, the report gives this concentration context: present practices of use and concentration described in the safety assessment. That language is the safe-use context shown for this page.

Conditions

Formulation Reading

For formula review, begin with the exact INCI identity and the ingredient group covered by the CIR assessment. If the material is benzalkonium montmorillonite, 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 benzalkonium montmorillonite 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.
