Lactones are a family of aromatic molecules known for their creamy, milky, and slightly fruity character. Their scent recalls warm milk, ripe peach skin, or coconut cream — soft, smooth, and delicately sweet. In perfumery, lactones bring roundness and warmth, creating a seamless transition between notes. They are commonly used in gourmand, woody, and fruity fragrances, where they add depth and natural harmony. Acting as a bridge between heart and base notes, lactones provide a velvety, comforting texture that makes the perfume feel rich and enveloping.
