C12-18 Acid Triglyceride

C12-18 Acid Triglyceride is an emollient lipid (medium/long-chain fatty acid triglycerides) typically used at a few percent up to higher levels to improve slip and barrier feel; it is not a pH-dependent active and has low inherent reactivity. Clinical experience and patch-test data for similar triglyceride emollients show a very low rate of irritation, though a small subset of highly reactive or compromised-skin patients can still experience stinging or contact reactions to any lipid vehicle or impurities. Given its generally excellent tolerability but non-zero risk in severe sensitivity populations, it fits 'very gentle' rather than completely inert. Safety Notes: C12-18 Acid Triglyceride (a medium-to-long-chain triglyceride emollient) appears at low levels (~0.1–1%) as a slip agent/emollient adjunct in lotions, serums, and facial cleansers, especially where it supports sensory feel without materially changing the oil phase. In leave-on creams, balms, and body butters it is commonly used as a primary emollient/oil-phase component and can reach ~20–60% in anhydrous or near-anhydrous consumer products (balms, ointment-style moisturizers, cleansing balms), with rinse-off formats typically lower due to surfactant system limits. No specific EU/FDA maximum restriction is generally applied to this type of triglyceride; practical upper limits are driven by texture, stability, and packaging.
