Sodium caprylate is widely used in the food industry as a preservative and antimicrobial agent. It helps extend the shelf life of products by inhibiting the growth of bacteria, yeast, and molds. This makes it particularly valuable in baked goods, dairy products, and processed foods.

In the pharmaceutical and cosmetic industries, it serves as an emulsifier and stabilizer, enhancing the texture and consistency of creams, lotions, and ointments. Its antimicrobial properties also make it effective in formulations designed to treat skin infections or maintain product hygiene.

Additionally, sodium caprylate is utilized in dietary supplements, often marketed for its potential to support gut health by balancing intestinal flora and combating harmful microorganisms. Its versatility and safety profile make it a valuable ingredient across various applications.
