3.Application scope and Usage
Decanoic Acid is a natural medium-chain fatty acid, which is mainly used in food additives, the pharmaceutical field (antibacterial agents, drug carriers), cosmetics (emulsifiers, moisturizers), and industrial applications (lubricants, plastic additives).
4.Package and Storage
Caproic acid is packaged in 25kg HDPE plastic drums or aluminum drums. For food-grade products, nitrogen must be filled for protection. It should be stored in a cool and dry place (<25℃), sealed tightly to prevent moisture and oxidation, and kept away from strong alkalis and oxidants. The shelf life is 24 months.
