Description

Alpha-ionone (CAS 127-41-3 ), also known by its FEMA 2594 designation, is a synthetic aroma chemical prized for its violet, woody, and orris-like scent profile. It is used across fragrance and flavor manufacturing as a key building block for fine perfumery and food flavoring systems. In fine fragrance and personal care formulations, alpha-ionone contributes a soft violet and floral character to perfumes, body lotions, and hair care products. It blends effectively with rose, iris, and musky bases to create sophisticated olfactory profiles. Food and beverage manufacturers use it as a FEMA-approved flavoring agent to impart berry, raspberry, and woody nuances in confectionery, baked goods, and beverages. It is a versatile component for creating realistic fruit profiles in various applications. In functional flavor systems, it supports the construction of complex top and heart notes where natural orris or violet extracts would be cost-prohibitive. This makes it an essential tool for flavorists seeking high-quality results at a competitive price point. Printing and packaging applications leverage its scent stability in scented inks and encapsulated fragrance coatings for consumer packaging. This ensures a long-lasting sensory experience for the end consumer throughout the product's shelf life. Alpha-ionone is supplied as a clear to pale yellow liquid. It is available in flavor-grade and fragrance-grade specifications, with FEMA 2594 status confirming its suitability for food and beverage use across global markets. Standard packaging ranges from small drums to bulk quantities depending on application volume requirements. Our supply chain ensures that the product meets rigorous quality standards for consistency and purity in every batch delivered. Contact us for supply of alpha-ionone Request Quote
