What it is
Rhus Verniciflua Peel Wax is a natural wax derived from the fruit peel of Rhus verniciflua, the East Asian lacquer tree. In sunscreen and skincare formulas it functions mainly as a structuring and viscosity-building agent, helping to thicken emulsions, stabilize the oil phase, and contribute a smooth, cushioned skin feel. It is most often encountered as a minor textural ingredient rather than a primary active.
Safety & warnings
Rhus verniciflua is the same botanical genus associated with urushiol, the contact allergen in poison ivy and lacquer sap, so individuals with known sensitivity to this plant family may wish to exercise caution; however, the refined wax fraction used in cosmetics is processed to remove the reactive sap components. As with other plant waxes, the finished material is generally well tolerated topically.
Origin & sourcing
Plant-derived. It is sourced from the peel of the fruit of Rhus verniciflua, a tree native to East Asia that is also the source of traditional urushi lacquer.
