In this report, the ingredient list includes Dimethyl Stearamine, Dimethyl Lauramine, Dimethyl Myristamine, Dimethyl Palmitamine, Dimethyl Behenamine, Dimethyl Cocamine, Dimethyl Tallowamine, Dimethyl Hydrogenated Tallowamine, and 1 more.

Safety Conclusion

The conclusion for Dimethyl Stearamine 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

The CIR Expert Panel concluded that dimethyl stearamine, dimethyl lauramine, dimethyl myristamine, dimethyl palmitamine, dimethyl behenamine, dimethyl cocamine, dimethyl tallowamine, dimethyl hydrogenated tallowamine and dimethyl soyamine are safe in the present practices of use and concentration as currently used in non-coloring hair care products, as described in this 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 Dimethyl Stearamine, 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 Dimethyl Stearamine 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.
