Pentadecanoic acid

Pentadecanoic acid (CAS 1002-84-2, EC 213-693-1) is a saturated odd-chain fatty acid also identified as C15:0, C15 acid, or NSC 28486. It carries no E-code designation and is classified under HS code 29159000. It belongs to the saturated fatty acid series and is commercially positioned within the surfactant and emulsifier category.

In personal care formulations, pentadecanoic acid functions as an emulsifier and hair conditioner by reducing interfacial tension between oil and water phases, enabling stable emulsion formation. In metalworking and lubricant applications, its carboxylic acid group adsorbs onto metal surfaces, forming a boundary film that reduces friction and wear under load.

Pentadecanoic acid is supplied as a white powder or flakes and is subject to REACH registration requirements for EU market supply. Procurement teams should confirm grade suitability against FCC or Ph.Eur. standards depending on end-use application. Standard industrial packaging applies; documentation including SDS and CoA is available upon request.
