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 Alkyl PEG Ethers.
Safety Conclusion
The conclusion for Alkyl PEG Ethers 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: 10%; 1.35%; 15%; 1.25%. That language is the safe-use context shown for this page.
