1. Adsorption type deodorant
Adsorption type deodorant removes odor by physical adsorption. This type of deodorant usually contains materials with high specific surface area, such as activated carbon, zeolite and silica gel. Activated carbon is the most commonly used adsorbent, which can effectively capture odor molecules in the air. Zeolite and silica gel are also widely used in odor control because they have good pore structure and can adsorb and remove a variety of odor molecules.
2. Neutralization type deodorant
Neutralization type deodorant neutralizes odor molecules through chemical reaction. This type of deodorant usually contains some chemicals, such as acid-base neutralizers or reactive compounds, which can react chemically with odor molecules to change their chemical properties and reduce or eliminate odor. For example, some deodorants contain amino acids or ester compounds, which can react with odor molecules to produce odorless or lighter odor products.
3. Masking type deodorant
Masking type deodorant masks the original odor by releasing substances with strong aromatic odors. These deodorizers usually contain fragrances or aromatic compounds that can cover or mask unpleasant odors, making the environment smell fresher. Common masking deodorizers include air fresheners, scented candles, and sprays.
4. Biodegradable deodorizers
Biodegradable deodorizers remove odors through a biodegradation process. These deodorizers usually contain beneficial microorganisms or enzymes that can break down the raw materials of odor molecules, thereby removing odors. For example, some deodorizers have enzymes added to break down urine and other organic waste, effectively removing odors.
