Hydnocarpus (Cactus) Oil

What is Hydnocarpus (Cactus) Oil?

Hydnocarpus (Cactus) Oil is a plant-derived fixed oil extracted from the seeds of trees in the Hydnocarpus genus, native to tropical regions of Asia. Despite the 'cactus' descriptor in its INCI name, it originates from woody plants in the Flacourtiaceae family, not true cacti. This oil is categorized as a vegetable oil in cosmetic formulations, where it serves primarily as an emollient and skin conditioning agent. Composed mainly of unique cyclopentenyl fatty acids like chaulmoogric and hydnocarpic acids, along with triglycerides, it works by forming a lightweight barrier on the skin's surface. This helps to soften rough textures, enhance product spreadability, and dissolve lipophilic ingredients, contributing to overall formula stability and sensory feel in creams, lotions, and serums.
