Use caution with:
High-concentration L-Ascorbic Acid Strong Acids Strong Alkalis High Electrolyte Concentrations
Glyceryl Stearate is a non-ionic emulsifier and is generally very compatible with most cosmetic ingredients; it works synergistically with co-emulsifiers like PEG-100 Stearate and fatty alcohols to stabilize O/W emulsions. Strongly acidic environments (pH below 4) or high alkalinity can hydrolyze the ester bond, reducing efficacy. High electrolyte concentrations may disrupt emulsion stability.
Formulation notes
Glyceryl Stearate (CAS 11099-07-3) is the monoester of glycerin and stearic acid; it is self-emulsifying only when combined with a co-emulsifier. It is considered safe and well-tolerated; no specific regulatory concentration restrictions in major markets (EU, US). Often used in conjunction with PEG-100 Stearate as a pre-blended SE (self-emulsifying) grade. Add to the oil phase during formulation, typically at 65–75°C.
