Caprylic acid is a medium-chain saturated fatty acid naturally found in coconut and palm oils, as well as in dairy products. Being a medium-chain fatty acid (C8) means its molecule contains between 6 and 12 carbon atoms.
In cosmetics, it is valued for its antimicrobial and soothing properties, making it a common ingredient in formulations for sensitive skin.
Thanks to its stability, caprylic acid helps preserve product freshness and prevent microbial growth. It also contributes to skin hydration by strengthening the protective barrier and reducing moisture loss.
When combined with other fatty acids, it is used in hair care products to add softness and help hair strands become more resilient to external factors.
