Aldehyde C-14 (Gamma Undecalactone)

Gamma Undecalactone, commonly known in perfumery as Aldehyde C-14 or Peach Aldehyde, is a premium aroma chemical valued for its rich, juicy peach character and creamy, fruity warmth. Despite its traditional name, it is not chemically an aldehyde but a lactone, prized for its smooth, velvety scent and excellent substantivity. It delivers a delicious blend of ripe peach, apricot, creamy coconut, and sweet lactonic notes, adding natural fruitiness, softness, and richness to fragrance compositions. Gamma Undecalactone is an essential ingredient for creating realistic peach accords, tropical fruit notes, creamy florals, and gourmand fragrances. It blends exceptionally well with jasmine materials, Hedione, Linalool, Phenyl Ethyl Alcohol, Benzyl Salicylate, Vanillin, Ethyl Vanillin, Coumarin, musks, sandalwood materials, and fruity aroma chemicals. Beyond fine fragrances, Gamma Undecalactone is widely used in soaps, shampoos, body washes, lotions, creams, candles, air fresheners, and other fragranced personal and household care products.
