Safety re-evaluation finds unsupported cosmetic use for five glyceryl monoesters, indicating insufficient evidence and absence of commercial application.
The Expert Panel for Cosmetic Ingredient Safety (Panel) considered whether the safety of Glyceryl Collagenate, Glyceryl Sesquioleate, Glyceryl/Sorbitol Oleate/Hydroxystearate, Glyceryl Stearate/Maleate, and Glyceryl Thiopropionate as used in cosmetics should be reassessed. The Panel considered that there were no newly available safety data related to these ingredients and no reported uses in cosmetics. The Panel concluded, based on the lack of sufficient data and the lack of reported uses, that the use of these ingredients in cosmetics is not supported.
