Limnanthes Alba (Meadowfoam) Seed Oil

What is Limnanthes Alba (Meadowfoam) Seed Oil?

Limnanthes alba (meadowfoam) seed oil comes from the seeds of the meadowfoam plant, a native North American species grown for its oil-rich seeds. The oil is mechanically pressed or extracted, yielding a light, non-greasy liquid rich in long-chain fatty acids, particularly 5-eicosenoic acid (around 60%), along with smaller amounts of other unsaturated fats. This unique composition gives it exceptional oxidative stability, outperforming many common seed oils. In cosmetics, it belongs to the emollient and skin-conditioning category, commonly found in moisturizers, serums, lip balms, and deodorants. It functions by mimicking skin's natural lipids, helping to smooth surface irregularities, enhance product spreadability, and form a breathable barrier that limits water evaporation without clogging pores. Its stability makes it ideal for natural formulations needing longevity.
