About
An ethoxylated phenyl ether used as a specialty fragrance material. Thin public data — defaulted to a conservative yellow.
Alpha-ethoxyphenetole (CAS 5426-78-8) is a specialty fragrance material with an ether/acetal architecture. Publicly available SCCS/CIR cosmetic safety monographs are limited. Acetal-type structures can hydrolyze under acidic conditions to regenerate the corresponding aldehyde, which is a relevant formulation consideration. No established sensitization or carcinogenicity concerns have been flagged for this specific structure, but the absence of data is itself the primary reason for a conservative rating. RIFM/IFRA presumably manage its use; no leave-on safety case can be made from public literature alone.
