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 Sodium Lauryl Sulfate, Ammonium Lauryl Sulfate.
Safety Conclusion
The conclusion for Sodium Lauryl Sulfate 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: In products intended for prolonged contact with skin, concentrations should not exceed 1%.. That language is the safe-use context shown for this page.
Conditions
Sodium Lauryl Sulfate and Ammonium Lauryl Sulfate appear to be safe in formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin.
Formulation Reading
For formula review, begin with the exact INCI identity and the ingredient group covered by the CIR assessment. If the material is Sodium Lauryl Sulfate, 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 Sodium Lauryl Sulfate 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
CIR reviews are long documents, and the practical answer is usually buried in the conclusion and the table of current practices. This summary keeps those CIR facts in one indexable page for Sodium Lauryl Sulfate, with source details retained at the bottom for audit.
