amber spirolene
Amber spirolene is a synthetic fragrance agent known for its medium-strength dry woody amber odor and long-lasting substantivity.
General Material Description
Amber spirolene is a synthetic fragrance compound belonging to the chemical class of spirodioxolanes. Its molecular formula is C17H28O2. This compound exhibits a dry, woody amber, vetiver, and powdery musk character often described as fruity and balsamic when diluted. Common synonyms include hexahydrotetramethyl spirodioxolane methanonaphthalene and the trade name ysamber (Symrise). Amber spirolene is typically derived through complex synthetic routes involving spiro-structures incorporating methanonaphthalene moieties. It is listed in chemical databases such as PubChem, providing standard identifiers and physicochemical data. The material is usually supplied as a liquid and used in fragrance and perfumery industries for its appealing amber scent profile.
Occurrence, Applicability & Potential Uses
Amber spirolene does not occur naturally but is synthesized for use as a fragrance ingredient. Its primary application is as a fragrance agent imparting a dry, woody amber aroma with additional notes reminiscent of musk, moss, cedar, and vetiver. This compound finds use in perfuming agents and diffusion products, contributing to oriental and woody accords. Amber spirolene is compatible with various bases such as lotions, shampoos, soaps, and cleaners, providing good substantivity and stability. Usage recommendations align with IFRA (International Fragrance Association) standards (Global), which allow up to 10% concentration in fragrance concentrates for safe formulation. Its application enhances complex fragrance compositions requiring persistent and multifaceted amber notes.
Physico-Chemical Properties Summary
Amber spirolene has a molecular weight of approximately 264.41 g/mol and presents as a liquid with a specific gravity ranging from 1.044 to 1.054 at 25 °C. Its refractive index varies between 1.499 and 1.509 at 20 °C, indicating moderate optical density. The vapor pressure is low at 0.012 mmHg at 20 °C, contributing to its long-lasting odor presence. The flash point is about 93 °C (200 °F), denoting moderate volatility and safe handling under proper storage. It dissolves readily in alcohol but is insoluble in water, guiding solubility considerations in formulations. Recommended storage conditions involve cool, dry places away from heat and light to preserve stability over an expected shelf life of at least 24 months. These properties support its use in diverse cosmetic and cleaning product bases while retaining fragrance integrity and performance.
FAQ
What is amber spirolene and what are its main characteristics?
Amber spirolene is a synthetic fragrance ingredient characterized by a dry, woody amber scent with additional notes of powdery musk, vetiver, and subtle fruity accents. Chemically, it is a spirodioxolane derivative with the molecular formula C17H28O2. The compound is used primarily for its aromatic profile in perfuming and diffusion applications, offering medium intensity and long-lasting substantivity. It is recognized under several synonyms, including ysamber, and is valued in fragrance chemistry for its distinctive amber and woody odor.
How is amber spirolene used and where is it commonly applied?
Amber spirolene is used primarily as a fragrance agent in cosmetic products, such as perfumes, lotions, shampoos, and soaps. It imparts complex amber, woody, and musk notes that enhance oriental and balsamic fragrance accords. Its stability in various product forms, including body lotions and cleaning agents, makes it suitable for multiple applications. The compound is generally applied in concentrations up to 10% within fragrance concentrates following IFRA (Global) guidelines, ensuring optimal scent performance without compromising safety.
What safety and regulatory considerations are associated with amber spirolene?
Amber spirolene is classified under European regulations as an irritant to eyes, respiratory system, and skin and is harmful to aquatic environments, necessitating careful handling and usage. It holds no significant hazards under OSHA classification but requires precautionary measures such as avoiding skin contact and environmental release. IFRA (Global) provides usage limits recommending up to 10% concentration in fragrance concentrates. It is not approved for flavor use. Proper storage and adherence to safety data sheets avoid potential risks during formulation and application.
