Application

Capric acid, a straight-chain saturated fatty acid also known as decanoic acid, serves a versatile role in various applications due to its unique properties. It appears as a white crystalline solid and has a fatty, rancid odor reminiscent of goats, a quality from which its name is derived. Primarily, capric acid is utilized in the manufacture of esters that are integral to creating artificial fruit flavors and perfumes. Beyond its use in flavors and fragrances, it acts as an intermediate in diverse chemical syntheses. Naturally occurring in small quantities in coconut oil and palm kernel oil, capric acid also plays significant biological roles-as an antibacterial and anti-inflammatory agent, and as a metabolite in humans, plants, and algae. Furthermore, as a component of volatile oils and various fats, it contributes to the composition of goat milk along with related fatty acids like caproic and caprylic acid.
