  • Applications

    Citronellyl tiglate (CAS 24717-85-9) is a naturally inspired ester of citronellol and tiglic acid that emits a sweet floral-fruity note, making it a valued fragrance modifier in fine perfumes, air fresheners, scented candles and diffuser oils; it also serves as a fixative in skin-care cosmetics, shampoos and personal-care products, a flavor enhancer for fruit-profile foods and beverages, a masking agent for surfactant odors in detergents, an eco-friendly insect-behaviour disruptor, and an analytical reference in olfactory research, where it broadens scent palettes and prolongs aroma longevity when blended with aldehydes, lactones and other terpenoids.
