Sodium alginate is a natural polysaccharide derived from alginic acid found in the cell walls of brown seaweed. Sourced from marine plants, it has excellent biocompatibility, biodegradability, and gel-forming abilities.

Deodorizing Principle

Sodium alginate has high hydrophilicity and a large specific surface area. Its adsorption and deodorizing properties are mainly related to the carboxyl, hydroxyl, and ether bonds in its structure. These functional groups provide active sites for interaction with target substances, enabling it to effectively adsorb odor molecules in the air, including volatile organic compounds (VOCs), ammonia, hydrogen sulfide, and other common sources of unpleasant odors, thereby achieving deodorizing effects.
