Description

Eucalyptol (CAS 470-82-6 ), also known commercially as cineole, is a naturally derived cyclic ether extracted primarily from eucalyptus oil. It functions as both a flavoring agent and a functional solvent across food, fragrance, and personal care manufacturing. In oral care formulations, such as toothpastes, mouthwashes, and breath fresheners, it delivers a characteristic cool, camphoraceous flavor profile recognized under FEMA 2465 . Fragrance compounders use it as a top-note ingredient in fine fragrances and air care products. It is frequently utilized in functional perfumery where a fresh, medicinal character is required. In personal care, it acts as a penetration-enhancing carrier in topical formulations, improving the delivery of active ingredients through the skin barrier. Food and beverage manufacturers incorporate it at controlled use levels to impart minty, herbal notes in confectionery, baked goods, and liqueurs. This versatile compound is essential for creating complex flavor profiles in the food industry. The material is supplied as a colorless to pale yellow liquid, typically in drum and IBC quantities for industrial buyers. It is available in food-grade and cosmetic-grade specifications to meet various regulatory requirements. High-purity grades commonly exceed 99% eucalyptol content for flavor and fragrance applications. Natural and synthetic sourcing options exist, with natural-origin material derived from eucalyptus or rosemary oil commanding preference. These natural options are particularly favored in clean-label formulations. The product maintains high quality standards to ensure consistency across large-scale manufacturing batches and diverse industrial applications. Contact us for supply of Eucalyptol Request Quote
