Ionone

CAS: 8013-90-9

Overview

Ionone (CAS 8013-90-9 ) is a naturally derived fragrance and flavor compound obtained from the oxidative cleavage of carotene. It is available commercially as a mixture of alpha and beta isomers.

It delivers the characteristic violet, woody, and orris-like scent profile that perfumers and flavorists rely on across both fragrance and food applications. This versatile chemical is essential for modern scent design.

In fine fragrance and personal care formulations, it provides the floral-powdery violet note found in perfumes, body lotions, and hair care products. It is highly valued for its ability to blend with other floral notes.

Food and beverage manufacturers use it as a flavoring agent to impart berry, raspberry, and woody nuances in confectionery, baked goods, and beverages. It adds a sophisticated depth to fruit-based flavor profiles.

Cosmetic formulators also incorporate it into soaps and detergents where a lasting floral character is required. In tobacco flavoring, it contributes depth and smoothness to various blended profiles for the industry.

The product is supplied as a pale yellow to yellow liquid. It is available in alpha-ionone, beta-ionone, and mixed isomer grades to suit specific fragrance or flavor performance requirements for industrial use.

Food-grade and fragrance-grade specifications are standard across the market. FCC -compliant material is available for use in regulated food and beverage applications to ensure safety and quality standards.
