Trilaurin

Trilaurin (glyceryl trilaurate) is a fatty acid triglyceride used primarily as an emollient/texture agent, typically at low to moderate concentrations, and it is not a reactive acid, surfactant, or preservative class commonly associated with stinging. Available safety and patch-test experience for triglyceride emollients indicates low irritation potential, though compromised eczema skin can still react to occlusive lipids or formulation context, so it is best categorized as very gentle rather than inert. Safety Notes: Trilaurin (glycerol trilaurate) is a niche lipid/emollient and structuring agent that most often appears at very low levels as part of a blend (typically ~0.01–1%) in leave-on creams/lotions and some rinse-off cleansers where it supports slip and texture rather than being a headline active. In consumer-available specialty anhydrous balms, solid cleansing bars, and lipid-base products where it functions as a primary oil-structurant/emollient, observed use can rise into the mid-to-high single digits; ~10% represents the upper end seen in OTC products before texture/waxiness and cost typically become limiting. It is not specifically restricted by major cosmetic regulations (EU/FDA) beyond general safety requirements, so the practical market range is driven mainly by sensorial and formulation constraints rather than legal limits.
