Meadowfoam Seed Oil is a vegetable oil extracted by a cold process (hexane free) from the seeds of the Limnanthes Alba plant. It contains omega-6 and omega-9 fatty acids. It brings a good emolliency without tackiness and it is strongly photostable because it possesses a high level of oxidative stability mainly due to the position of the double carbon bond on Δ5. The oxidative stability is defined as the Oil Stability Index (OSI) that is the duration (in hours) for which the oil starts to be oxidised. This commonly used method exposes a sample of oil to oxygen at a determined temperature.
