Brassica Campestris (Rapeseed) Seed Oil
What is Brassica Campestris (Rapeseed) Seed Oil?
Brassica Campestris (Rapeseed) Seed Oil comes from the seeds of Brassica campestris, an annual plant in the mustard family grown worldwide for its nutrient-dense seeds. The oil is obtained through cold-pressing or solvent extraction, then refined to remove impurities for cosmetic applications. Compositionally, it features a mix of fatty acids, predominantly oleic acid, alongside linoleic and alpha-linolenic acids, forming a semi-occlusive layer on the skin. In skincare formulations, it acts as an emollient and skin conditioning agent, enhancing product texture and aiding in moisture retention by reducing water evaporation from the skin surface. This makes it ideal for lotions, serums, and balms where a non-greasy finish is desired. Its botanical origin provides a natural alternative to synthetic conditioners, supporting skin suppleness without heavy residue, though it may interact with certain skin microbes.
