Uses:
- Food Preservation: Used as a food additive (E280) to prevent mold growth in baked goods and as a preservative.
- Animal Feed: Used to preserve and improve the quality of animal feed.
- Industrial Applications: Used in the manufacture of herbicides, plastics, and as a chemical intermediate in various processes.
- Fungal Inhibitor: Common in some personal care products and as a component in cosmetics to prevent microbial growth.
