Galaxolide (Cat No.: R051638) is a synthetic polycyclic musk fragrance composed of a mixture of diastereomers, with the molecular formula C₁₈H₂₆O. It is widely used in perfumes, personal care products, detergents, and household cleaners due to its long-lasting, sweet, musky scent. Galaxolide’s chemical structure includes a tetramethyl-substituted hexahydroindanone core, contributing to its high lipophilicity and environmental persistence. Although popular for its fragrance stability, Galaxolide has raised concerns regarding bioaccumulation and aquatic toxicity, prompting ongoing evaluations of its environmental and health safety profiles.
