Description

Irone CAS NO 79-69-6 is a high-purity, naturally occurring ketone belonging to the ionone family, prized for its distinctive woody, violet, and iris-like aroma. This compound is a key fragrance ingredient, valued for its ability to impart sophisticated and long-lasting olfactory notes. It is essential for manufacturers in the flavor and fragrance, cosmetics, and fine chemical synthesis industries seeking premium aroma chemicals.

Application

• Fragrance Formulation: A core component in creating and enhancing perfumes, colognes, and eau de toilettes, particularly for floral, woody, and powdery accords.
• Cosmetic & Personal Care: Used as a fragrance ingredient in soaps, lotions, creams, shampoos, and other scented personal care products.
• Flavor Enhancement: Employed in trace amounts to add subtle, complex notes to certain food and beverage flavorings.
• Aromatherapy & Home Scents: Incorporated into essential oil blends, diffuser oils, candles, and air fresheners for its calming and elegant scent profile.
