About
A saturated branched-chain aldehyde used for aldehydic fragrance effects. Less reactive than unsaturated aldehydes but public cosmetic data is thin.
Tetramethyl-octanal (CAS 114119-97-0) is a branched saturated C8 aldehyde used as a specialty perfumery material. Unlike conjugated dienals, saturated aldehydes are substantially less protein-reactive, though they can still contribute to overall fragrance sensitization burden. Public SCCS/CIR monographs specific to this structure are limited, and RIFM/IFRA assessments are typically held privately by the industry. Used at low percentages in fine fragrance; not an EU Annex III declared allergen. Expected to be skin-compatible at normal use levels but default to caution without a dedicated safety monograph.
