Description
Alpha-Hexylcinnamaldehyde (CAS 101-86-0, EC 202-983-3) is a synthetic aromatic aldehyde commonly identified by the abbreviations HCA and FEMA 2569, and also referenced as 2-benzylideneoctanal or Hexylcinnamaldehyde. It carries no assigned E-code and belongs to the flavors and fragrances chemical category.
In personal care formulations, HCA functions as a fragrance ingredient, contributing a jasmine-like character to fine fragrances, soaps, and rinse-off products. In plastics and coatings, it acts as a UV absorber by capturing ultraviolet radiation through its conjugated aldehyde structure, helping to protect polymer matrices and printed substrates from photodegradation.
Alpha-Hexylcinnamaldehyde is supplied as a neat liquid conforming to FEMA and IFRA quality standards and is subject to REACH registration requirements within the EU. It is available in standard drum and IBC packaging formats suited to industrial procurement volumes.
