What is "Seed Oil" and what is its utility?
What is Seed Oil?
Seed Oil is the INCI (International Nomenclature of Cosmetic Ingredients) term for seed oil on skincare packaging. Most vegetable oils are derived from seeds. On the ingredient list, a vegetable oil is presented by its Latin name followed by the INCI designation "seed oil" or "extract". Thus, you can find on the packaging: Helianthus Annuus Seed Oil to designate sunflower vegetable oil or Argania Spinosa Seed Oil for argan vegetable oil.
What should we understand by the term "Seed Oil" on packaging?
The term "seed oil" indicates that the oil used in the formulation is a virgin vegetable oil, not an esterified oil. The latter is referred to by names such as "ethylhexyl palmitate" or "coco caprylate caprate". Due to the treatments they have undergone, esterified oils are concentrated in vitamins, essential fatty acids, and phytosterols (plant actives). Indeed, esterified oils have been enhanced at the fatty acid level to stabilize them and make them penetrative. On the other hand, a virgin vegetable oil retains all the properties of the seeds used.
