Sal Butter (Shorea robusta seed fat) is a plant-derived butter rich in stearic and oleic acids used in skincare to soften, condition, and form an occlusive barrier that reduces transepidermal water loss. It is valued for its emollient texture and oxidative stability in balms, creams, and lip products.
