Galaxolide

Galaxolide is a synthetic musk fragrance compound widely used in perfumery and in a range of consumer products to impart a lasting, musky scent. It belongs to the class of macrocyclic musk compounds and is not derived from natural essential oils. In commercial formulations, galaxolide is often abbreviated as HHCB.

As a fragrance ingredient, galaxolide is valued for its odor potency at very low concentrations, contributing lasting sillage and longevity to products. It is commonly found in perfumes, cosmetics, personal care items, detergents, and household products, where it is typically used in trace to low parts-per-million levels depending on the product and regulatory guidelines.

Production and usage practices: galaxolide is manufactured synthetically and distributed by fragrance houses and chemical suppliers for incorporation into a wide array of consumer goods. Its inclusion helps achieve a consistent musk note across many formulations.

Environmental and safety considerations: galaxolide has been detected in environmental samples, including wastewater and some aquatic organisms, raising discussions about persistence and potential bioaccumulation. Safety assessments generally support its use within established regulatory limits, and many formulators follow industry guidelines (such as those from fragrance associations) to manage exposure and release. Regulators in different regions may have varying recommendations or restrictions, and labeling requirements for fragrance ingredients can apply in some jurisdictions.

History and context: galaxolide became popular in the mid- to late 20th century as part of the broad adoption of macrocyclic musks in mainstream fragrance and consumer products. It remains a common, though increasingly scrutinized, component of many scented goods.
