Deodorants are primarily classified as follows:

1. Adsorption deodorant

Containing substances that can perform excellent adsorption, utilizing intermolecular van der Waals forces to adsorb odors, with a larger surface area and larger air volume, it can reduce the concentration of odors in the air to achieve the desired effect.

2. Masking deodorants

Containing natural aromatic oils, spices, and other substances that can mask odor, it is primarily aimed at many environments that are difficult to remove odors, and mixed gases in proportion to reduce odor.

3. Oxidative deodorant

Substances with strong oxidizing properties such as NaClO or chlorine can oxidize the organic matter in the odor into compounds with lighter odor, which are then absorbed and purified by acid and alkali.

4. Salt compounds

It can be used as a deodorant, for example, a mixture of divalent iron ions and ascorbic acid reacts with foul smelling substances such as ammonia and mercaptan to make it odorless. In addition, the coordination of trivalent iron derivatives and metal complexes reacts with mercaptan or sulfur to eliminate odors.

5. Acid and alkali preparations

It can serve as a deodorant, such as zinc oxide reacting with hydrogen sulfide to remove hydrogen sulfide gas from the air, and wood essential oil components such as flavonoids and tannic acid continuously removing odorous substances through a series of effects and reactions.
