Glyceryl Distearate

Glyceryl distearate is a fatty acid ester used mainly as an emollient/emulsifier, typically around ~1–5% in creams and lotions, and it is generally well tolerated in patch testing with low irritancy potential. In highly reactive or eczematous skin, occlusive lipid-esters can occasionally contribute to stinging or follicular issues depending on the full formula, but true irritant reactions to this ingredient alone are uncommon. Given its widespread use in sensitive-skin moisturizers with infrequent reports of irritation, it fits best as a very gentle (0.2) ingredient rather than inert. Safety Notes: In commercial emulsions, glyceryl distearate is often used as an auxiliary emollient/pearlizing or consistency agent at low levels around 0.1–0.5% (e.g., lotions, facial cleansers, and shampoos where it mainly supports texture/opacity). Typical leave-on creams and body lotions commonly use ~1–5% as part of the primary emulsifier/structurant system, while high-structure consumer butters, cold creams, and anhydrous or high-wax balm-like products can reach ~8–12% to build viscosity and a waxy, occlusive feel. It is broadly permitted in major cosmetic regulations without a specific maximum, so the practical upper end is driven by aesthetics, stability, and processing rather than regulatory caps.
