Capryloyl Salicylic Acid
What is Capryloyl Salicylic Acid?
Capryloyl salicylic acid, often called lipohydroxy acid (LHA), is a lab-created ester of salicylic acid and caprylic acid. The addition of the eight-carbon capryloyl chain makes it more fat-loving than standard salicylic acid, improving its solubility in oily environments and skin penetration through lipid layers. Classified as a beta-hydroxy acid derivative, it appears in rinse-off cleansers, leave-on moisturizers, and targeted treatments within cosmetic products. It functions by mildly loosening bonds between dead skin cells for gradual surface renewal while conditioning the skin barrier. This dual action helps preserve hydration and suppleness. Due to its larger size, it releases salicylic acid slowly, supporting gentler application compared to plain BHA forms. Regulatory bodies like the EU CosIng database recognize it for keratolytic and conditioning roles in approved formulations.
