Glyceryl Dipalmitate

Glyceryl dipalmitate is a waxy emollient/structuring lipid (glycerol diester of palmitic acid) typically used at low-to-moderate percentages to improve texture and reduce transepidermal water loss, and it is not an inherently reactive active. Clinical and patch-test data for similar fatty acid glycerides show very low irritancy, but in severely compromised or acne-prone skin it can occasionally contribute to occlusion-related discomfort or follicular issues, so I rate it very gentle rather than fully inert. Safety Notes: Glyceryl dipalmitate is typically used as an emollient/structuring lipid and pearlizing/opacifying aid, and in mass-market leave-on lotions/creams it is often present at very low levels (around 0.05–0.5%) as part of a fatty phase blend. In richer anhydrous balms, body butters, cleansing creams, and some high-lipid sticks, it can be pushed much higher (commonly 2–5% and observed up to ~8%) to build viscosity, improve glide, and reinforce the lamellar/oily structure. It is not generally restricted by specific cosmetic regulations, so the upper end is mainly limited by sensorial waxiness, crystallization risk, and overall oil-phase design rather than legal caps.
