Auto-generated CPSR Part A draft with source citations
Function
Saturated long-chain fatty acid (C16:0). One of the two predominant free fatty acids in the stratum corneum lipid matrix alongside stearic acid (C18:0). Contributes to the crystalline lamellar structure underpinning barrier function at the equimolar ceramide:cholesterol:FFA (1:1:1) molar ratio. Functions as emollient, consistency agent, co-emulsifier, and skin-conditioning agent. Predominantly palm-derived in cosmetic supply chains; also present in tallow and some plant oils.

US Notes
Endogenous SC lipid component. No FDA or CIR restrictions. Palm-derived supply chain: EU Deforestation Regulation (EUDR) mandates plot-level traceability for palm oil and derivatives. RSPO Mass Balance or Segregated certification required for EU market compliance. Fully saturated — no oxidative stability concerns.
