IFRA to Prohibit 2,4-Double Conjugated alpha, beta Unsaturated Aldehydes
Posted: February 9, 2009
The International Fragrance Association (IFRA) is expected to prohibit the use of 2,4-hexadienal (CAS# 80466-34-8) and other 2,4-double conjugated alpha, beta unsaturated aldehydes as part of the 44th Amendment to the IFRA Code of Practice. The move follows the completion of a review of these materials' safety, which concluded their continued use in skin applications was not sufficiently supported by the data.
