Description

Camphor appears as a colorless or white colored crystalline powder with a strong mothball-like odor. About the same density as water. Emits flammable vapors above 150°F. Used to make moth proofings, pharmaceuticals, and flavorings.;Camphor oil appears as a colorless liquid with a characteristic odor. Flash point 125°F. Insoluble in water and generally less dense than water. Vapors heavier than air.;D-camphor appears as colorless or white crystals. Sublimes. Flash point 149°F. Burns readily with a bright, smoky flame. Penetrating aromatic odor. Pungent, aromatic taste followed by a sensation of cold.

Application

Synthetic camphor blocks serve a diverse range of purposes due to their unique properties and benefits. These blocks are known for their anesthetic, anti-inflammatory, antiseptic, and astringent characteristics, making them particularly effective in treating oily and acne-prone skin. With a scent reminiscent of eucalyptus, they provide a cooling and refreshing experience. Once absorbed by the skin, camphor combines with glucuronic acid in the body and is excreted through urine. While offering a slight stimulating effect on blood circulation and function, camphor must be used cautiously as high concentrations can cause irritation and numbness in peripheral sensory nerves. Traditionally derived from the evergreen Cinnamomum camphora tree, the synthetic version of camphor is now widely used. Its long-standing use in traditional Chinese medicine highlights its efficacy in treating pruritic skin diseases, fibrous tissue inflammation, neuralgia, and influenza. Moreover, the characteristic odor of synthetic camphor makes it useful in applications like mothballs, while its role as a plasticizer in celluloid showcases its versatility.
