  • Applications

    Mintlactone (CAS 38049-04-6) is a minty-green, slightly creamy flavor and fragrance ingredient used to build and refine mint profiles in foods and oral care (chewing gum, lozenges, toothpaste, mouthwash, beverages), extending freshness and clean-mouth perception while softening menthol harshness and blending well with menthol, menthone, carvone, and eucalyptol; in perfumery and functional scents for personal and home care (soaps, body washes, shampoos, detergents, air care, candles, fabric refreshers) it delivers bright cool top notes, rounds off rough edges, and offers good substantivity on surfaces and textiles, and can be microencapsulated or complexed with cyclodextrins for controlled, long-lasting release; in R&D it serves as a keystone for modern, less-bitter mint accords, background-odor masking, and a “fresh-clean” impression in reduced-sugar or plant-protein matrices, and as an analytical reference standard, with practical notes on stability across typical cosmetic/food pH ranges and the need to confirm local safety and regulatory limits before use at appropriate dosages.
