About

PENTAMETHYL-SPIROBICYCLOHEPTANE-DIOXANE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

Pentamethyl-spirobicycloheptane-dioxane (CAS 121251-67-0) is a spirocyclic fragrance combining a spiro-bicycloheptane skeleton with a dioxane ring and five methyl substituents. The GHS hazard profile includes H315 (causes skin irritation), H319 (causes serious eye irritation), and H411 (toxic to aquatic life with long-lasting effects). The dioxane ring is a chemically stable heterocycle, but the high degree of substitution may affect biodegradability. Under EU Regulation (EC) No 1223/2009, no specific cosmetic restrictions apply, but the compound's irritation and environmental hazard profile necessitate careful formulation management and adherence to IFRA guidelines.
