Description
Palmitoylethanolamide (PEA, CAS 544-31-0) is a naturally occurring fatty acid amide classified as a surfactant, also referenced under the trade names Impulsin and Palmidrol. It carries no assigned E-code and is identified under EC number 208-867-9 with molecular formula C18H37NO2.
In personal care formulations, PEA functions as a foam-boosting agent and hair conditioner by reducing interfacial tension between oil and water phases, improving lather stability and surface wetting. It also acts as an antistatic agent in hair care systems, neutralising charge build-up on fibre surfaces through its amphiphilic structure.
PEA is supplied as a white solid and is subject to REACH registration requirements for EU market access. Pharmaceutical-grade material may be evaluated against Ph.Eur. monograph standards where applicable. Procurement teams should confirm available pack sizes and certificate of analysis specifications directly with our technical sales team.
