Glyceryl Palmitate

Glyceryl Palmitate is a fatty acid monoester used primarily as an emollient/emulsifier in low percentages (typically ~0.1–5%) and is generally well tolerated, with a low rate of irritation in patch testing compared with surfactants, acids, or preservatives. In highly reactive or eczema-prone patients, it can still contribute to intolerance as a lipid-based excipient (rare contact allergy/follicular occlusion-related flare), so it is best classified as very gentle rather than inert. Safety Notes: In commercial skincare, glyceryl palmitate is most often used as a co-emulsifier/emollient in leave-on lotions/creams and cleansing products at low levels around 0.05–0.5% (commonly as part of emulsifier blends or to add slip/skin feel). Mid-range usage in moisturizers, sunscreens, and hair/skin conditioners is frequently ~1–3% to support lamellar structure and viscosity. High-strength consumer-available anhydrous balms, barrier creams, and rich body butters can reach ~5–8% when used as a primary structuring lipid/emollient; higher levels are uncommon due to waxy feel, crystallization risk, and formula stability constraints.
