Dicaprylyl ether is an oil derived from caprylic acid and is used to enhance the texture of the ingredient as well as of the skin and hair. Even being an oil, this magic ingredient is non-comedogenic and does not clog pores or cause acne breakouts. Dicaprylyl ether has fast-spreading capabilities and acts as an emollient and a solvent in formulations.

Dicaprylyl ether is derived from caprylic acid which is a fatty acid found in palm kernel oils and coconut oils. This fatty acid is esterified to separate caprylyl alcohol which is further etherified or dehydrated to form water and dicaprylyl ether. Therefore, Dicaprylyl ether can be synthetic or plant-derived.
