Chemical Properties

Camphor is a colorless glassy solid. Penetrating, characteristic odor.

Physical properties

Colorless to white, flammable granules, crystals or waxy semi-solid with a strong, penetrating, fragrant or aromatic odor. Odor threshold concentration is 0.27 ppm (quoted, Amoore and Hautala, 1983).

Uses

dl-Camphor is used as a plasticizer for celluloseesters and ethers; in the manufacture ofplastics and cymene; in cosmetics, lacquers,medicine, explosives, and pyrotechnics; andas a moth repellent.

Definition
