Common Name(s): Hevea brasiliensis seed oil,rubber tree seed oil,para rubber seed oil
DESCRIPTION
What It Does: Softens and nourishes skin with a lightweight, linoleic-rich oil from rubber tree seeds.
Why It's Used: Rubber tree seed oil is a sustainable byproduct of the rubber industry (from hevea brasiliensis seed, not the latex); rich in linoleic (c18:2, ~40%) and oleic (c18:1, ~27%) acids; mild and non-irritating.
How It Works: High linoleic acid content supports skin barrier lipid replenishment; oleic acid provides emolliency and penetration enhancement; tocopherols provide antioxidant stability; the seed oil contains no latex proteins (not from the tree sap).
Typically Found In: Skin care,barrier repair products,natural formulations,body lotions
