CAS: 3391-83-1
Musk R1, also known as Galaxolide (CAS: 3391-83-1), is one of the most widely used synthetic polycyclic musk compounds in the fragrance industry. It is a colorless to pale yellow viscous liquid or solid at room temperature. It possesses a clean, sweet, powerful, and persistent musky odor with woody and slightly floral nuances. Known for its excellent stability and longevity, it serves as a base note in many fragrance formulations.
Musk R1 is primarily used as a fragrance ingredient to impart a musky scent. It is a key component in perfumery, acting as a fixative and enhancing the overall aroma profile of fragrance compositions.
Its applications are widespread across various consumer products. It is found in fine fragrances (perfumes, colognes), personal care products (soaps, shampoos, deodorants, lotions, body washes), cosmetics, and a broad range of household products such as laundry detergents, fabric softeners, air fresheners, and surface cleaners. Its stability makes it suitable for use in products where other musks might degrade.
Musk R1 is generally considered safe for use in fragrances at specified concentrations. However, it is recognized for its environmental persistence and potential for bioaccumulation, leading to its identification as a potential PBT (Persistent, Bioaccumulative, Toxic) or vPvB (very Persistent, very Bioaccumulative) substance. Regulatory bodies like IFRA (International Fragrance Association) set usage limits to ensure consumer safety. It has a low potential for skin sensitization.
