Formaldehyde sodium bisulfite is a true chemical compound, not a mixture of two chemicals. For example, when formaldehyde is mixed with a proteinaceous material as described in U.S. Pat. No. 3,942,969, Mar. 9, 1976, volatile formaldehyde may be detected from this mixture; whereas no volatile formaldehyde is detected from the chemical compound formaldehyde sodium bisulfite. This chemical compound produces a slow release of formaldehyde only by the oxidation of the "sulfite" to the "sulfate."
