  • Applications

    Terpinene 4-acetate (terpinen-4-yl acetate, CAS 4821-04-9) is a terpenic ester used broadly in perfumery, personal care, and flavors for its fresh, herbaceous, slightly woody tea-tree/lavender nuance; it builds fougère, citrus, herbal, pine, and spicy accords, acting as a fragrance modifier to soften harsh terpenic notes, enhance bloom, and deliver a clean impression in soaps, detergents, shampoos, deodorants, creams, candles, and air care; in food flavoring it can be applied at very low levels to add citrus–herbal facets to beverages, confectionery, gum, and baked goods; in aroma-chemical manufacture it serves as a versatile intermediate and diluent, blending well with limonene, linalool, esters, and terpene alcohols to balance volatility; formulate to IFRA and local regulations, typically from trace to a few percent depending on end-use, and avoid strong acids/bases and prolonged heat/UV to limit hydrolysis.
