Uses2

  • Esters for perfumes and fruit flavor, base for wetting agents; intermediates; plasticizer; resins; intermediate for food-grade additives
  • Chemical intermediate for the synthesis of capryl imidazoline, ethyl caprate
  • In both the model membrane and guinea pig skin experiments, capric acid is used as an absorption enhancers.
