Product Name
Camphor, Synthetic, Blocks
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.
