What is Galaxolide CAS 1222-05-5?

Galaxolide is a synthetic polycyclic musk fragrance ingredient also known by the abbreviation HHCB. It has the molecular formula C18H26O, a molecular weight of about 258.40 g/mol, and the systematic name Hexamethylindanopyran.

What is the fragrance profile of Galaxolide?

Galaxolide has a clean, sweet, powerful musk character with woody and slightly floral nuance. It is valued for strong diffusion and long-lasting substantivity, which makes it useful as a base musk note in complex fragrance accords.

Where is Galaxolide commonly used?

It is used in fragrance compounds for laundry detergents, fabric conditioners, household cleaners, deodorizing products, air care systems, and selected personal care fragrances. It typically functions as a persistent musk note rather than as a single-note finished fragrance.

What are the main physical properties of Galaxolide?

Commercial Galaxolide is usually a colorless to pale yellow viscous liquid with a low vapor pressure at room temperature. It is practically insoluble in water and soluble in common fragrance solvents and organic systems.

Is Galaxolide regulated for fragrance use?

Galaxolide has been extensively evaluated as a fragrance ingredient, and earlier EU assessments concluded it could be used in cosmetic fragrance applications under the conditions reviewed. Because regulatory and IFRA requirements can change, each formulation should still be checked against current regional rules and customer limits.
