CAS: 127-41-3
Alpha Ionone is an aromatic ketone belonging to the ionone family, known for its distinct and highly valued fragrance profile. It possesses a delicate, floral, woody, violet-like scent, often with fruity nuances, particularly reminiscent of raspberry. While naturally occurring in various essential oils, it is predominantly produced synthetically for commercial applications due to its widespread use in perfumery and flavor industries. It is an important isomer among the ionones (alpha, beta, gamma), with alpha-ionone being characterized by its specific floral-violet aroma.
It is primarily used as a fragrance ingredient in a wide range of consumer products and as a flavoring agent in the food and beverage industry. Alpha Ionone also serves as a masking agent to neutralize or cover undesirable odors.
Applications include fine fragrances (perfumes, colognes), personal care products (e.g., soaps, shampoos, lotions, cosmetics), and household cleaning products (e.g., detergents, fabric softeners, air fresheners). In the food and beverage industry, it is utilized as a flavor component in products such as candies, baked goods, and various drinks.
Alpha Ionone is generally recognized as safe (GRAS) for use as a food additive within specified limits by regulatory bodies like the FDA. However, it can act as a skin sensitizer or allergen in some susceptible individuals, potentially causing irritation to the skin and eyes upon direct contact. It is a flammable liquid and should be handled with appropriate safety precautions, including good ventilation and avoidance of ignition sources. Occupational exposure limits should be observed.
