Product Overview

Applications

Documented applications: Uses: Main component of citronella oil, Present in many other volatile oils, [Merck Index] Used as flavoring agent, insect repellent, fragrance (soaps, detergents, creams, lotions, and perfumes), and chemical intermediate for citronellol and hydroxycitronellal, [HSDB], In soap perfumes, insect repellant., Citronellal is used in small amounts for scenting soaps and detergents. Its principal application is in the preparation of isopulegol, citronellol, and hydroxycitronellal., Among the plant families with promising essential oils used as repellents, Cymbopogon spp., Ocimum spp. and Eucalyptus spp. are the most cited. Individual compounds present in these mixtures with high repellent activity include alpha-pinene, limonene, citronellal, camphor and thymol. Finally, although from an economical point of view synthetic chemicals are still more frequently used as repellents than essential oils, these natural products have the potential to provide efficient, and safer repellents for humans and the environment., MEDICATION, Reported uses (ppm):, Table: Reported uses (ppm): (Flavor and Extract Manufacturers' Association, 1994) [Table#1696], Use Classification: Fragrance Ingredients, Flavouring Agent -> FLAVOURING_AGENT -> JECFA Functional Classes, Flavoring Agents -> JECFA Flavorings Index, Cosmetics -> Masking, Industry Uses: Fragrance, Consumer Uses: Fragrance, Household Products: Information on 29 consumer products that contain Citronellal in the following categories is provided:, • Auto Products, • Commercial, Institutional, • Inside the Home, • Personal Care, • Pesticides, • Pet Care, Methods of Manufacturing: DEHYDROGENATION OF BETA-CITRONELLOL OR BY CATALYTIC HYDROGENATION OF CITRAL, SYNTHETIC D, L-CITRONELLAL BY CATALYTIC REARRANGEMENT OF SYNTHETIC GERANIOL, NEROL, (+)-Citronellal is obtained from citronella oils by fractional distillation.
