About
ISOPROPYLMETHYLHEXENAL is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
Isopropylmethylhexenal is an unsaturated aliphatic aldehyde derivative functioning as a fragrance ingredient with powerful green, floral, and slightly citrus notes. Alpha,beta-unsaturated aldehydes are inherently more reactive than saturated aldehydes and have higher sensitisation potential. While not specifically restricted in EU CosIng Annexes, the unsaturated structure places it in a class of fragrance materials requiring attention to use levels. The IFRA/WHO framework for unsaturated aldehydes applies general sensitisation precautions.
