Dipentaerythrityl Hexacaprylate/Hexacaprate

Dipentaerythrityl Hexacaprylate/Hexacaprate is a non-volatile emollient ester used to improve slip and reduce tack, typically at a few percent up to higher levels in color cosmetics and sunscreens. As a large, chemically inert lipid-like molecule, it is generally low on irritant potential in patch testing and clinical use, with reactions more likely to be rare idiosyncratic intolerance or comedogenicity rather than true irritation. For highly reactive or barrier-compromised patients, I still score it above “exceptionally gentle” because any leave-on emollient at meaningful concentrations can occasionally sting on fissured eczema skin or contribute to occlusive discomfort in a subset of users. Safety Notes: Dipentaerythrityl Hexacaprylate/Hexacaprate is a lightweight emollient/texture and slip modifier most often used at very low levels (~0.05–1%) in leave-on serums, sunscreens, and makeup to improve spreadability and reduce greasiness. In richer leave-on creams, balms, lip products, and some anhydrous oil-gel/primer-type formulas, it can function as a primary emollient phase component and is seen in the ~10–40% range in consumer OTC products. There are no specific EU/FDA maximum limits for this type of cosmetic emollient ester, so the upper end is driven by sensory goals, solubility, and overall oil-phase design rather than regulatory caps.
