Neopentyl Glycol Dicaprylate/Dicaprate

Neopentyl Glycol Dicaprylate/Dicaprate is a low-polarity emollient ester used to improve slip and barrier feel, typically present at a few percent up to higher levels in moisturizers and makeup. As a large, non-volatile lipid ester it is generally non-stinging and shows low rates of irritation in standard use, but like other emollient esters it can still trigger mild irritation or follicular issues in a small subset of highly reactive or eczematous patients, especially under occlusion. Given sensitive-skin safety considerations, it fits best as very gentle rather than fully inert. Safety Notes: Neopentyl Glycol Dicaprylate/Dicaprate is a lightweight emollient/skin-conditioning ester used both as a minor slip/sensory modifier and as a primary emollient in anhydrous or low-water lipid phases. In mass-market leave-on lotions/serums it is often present at trace-to-low single digit levels (~0.1–5%) to improve spreadability and reduce greasiness, while higher-oil products (body oils, lip products, oil-based makeup/removers, balms, and water-resistant sunscreens) commonly use it around 10–25% as a key emollient. The upper end observed in consumer OTC products can reach ~30–35% where it functions as a major component of the oil phase; rinse-off products typically use lower levels due to cost and deposition needs.
