What it is
This is a fixed oil obtained from the seeds of the rapeseed plant, composed largely of oleic, linoleic, and linolenic fatty acids. It softens and conditions the skin, reinforces the surface lipid layer to help limit moisture loss, and contributes a light, spreadable emolliency to creams and lotions. In sun care it serves as part of the oil phase and as a vehicle that improves texture and skin feel.
Safety & warnings
Rapeseed oil is generally well tolerated and considered low-irritation. As a fatty plant oil it has moderate richness, so users who are very acne-prone may prefer to use it cautiously in heavy formulas; it is not a known fragrance allergen.
Origin & sourcing
Natural, plant-derived. It is cold-pressed or extracted from rapeseed (Brassica campestris) seeds.
