Stearyl Glycyrrhetinate (CAS 13832-70-7) is the stearyl ester of glycyrrhetinic acid derived from licorice root, designed as an oil-soluble anti-inflammatory and skin-conditioning agent for cosmetic formulations. The introduction of the lipophilic stearyl group significantly enhances oil solubility and skin affinity, improving transdermal absorption compared to conventional licorice derivatives. With assay ≥98% and cosmetic-grade quality, it is suitable for soothing creams, sun care, sensitive-skin products, and lip care formulations.
