What it is
Shorea Robusta Resin is obtained from the sal tree (Shorea robusta), native to South Asia, which yields a resinous exudate sometimes called sal dammar. In cosmetic formulas the resin and its derivatives contribute film-forming and conditioning properties that can improve the smoothness and feel of a product. The closely related butter and esters from the same tree are more common, while the resin itself is used less frequently.
Safety & warnings
Tolerability data specific to this resin in cosmetics are limited. As with other botanical resins, sensitive individuals may occasionally react, so patch testing is reasonable for reactive skin.
