Hydrogenated Palm Glycerides

Hydrogenated Palm Glycerides are a non-volatile, saturated lipid mixture used as an emollient/structurant in leave-on products, typically at a few percent to higher levels, and are generally well tolerated in patch testing with low inherent irritancy. In highly eczema-prone or follicularly reactive patients, heavy occlusive lipids can occasionally provoke stinging on fissured skin or trigger intolerance via occlusion/heat and barrier disruption in an already inflamed area, so I do not rate it fully inert. Overall, the clinical risk is low and consistent with a "very gentle" score for sensitive-skin use. Safety Notes: Hydrogenated Palm Glycerides is used as a lipid structurant/emollient and can appear at low levels (~0.1–1%) in lotions and facial creams to subtly thicken and improve slip. In anhydrous sticks/balms (lip balms, deodorant sticks, solid moisturizers) and some rich body butters, it is commonly used as part of the main structuring fat phase and can reach ~10–30% in consumer OTC products. Ranges are generally similar for leave-on and rinse-off, but the highest levels are most often observed in anhydrous leave-on formats where it functions like a waxy hardener.
