Food grade co2 description
Carbon dioxide is a compound containing carbon and oxygen. At atmospheric temperatures and pressures, carbon dioxide is in gaseous form. It is colorless, odorless, about 1.5 times heavier than air and a slightly acid gas. The gas is nonreactive, nontoxic and nonflammable. Solid carbon dioxide (dry ice ) is formed at a temperature of -78.5℃.
