How we scored it
Botanical leaf extract: all mass is plant-derived (n = 1). Extraction solvent leaves no counted mass. Natural mass 100% of total, NOI = 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Dominant feedstock is the dried leaf of Tephrosia purpurea, extracted with water, ethanol or a glycol/glycerin mixture and concentrated. No synthetic route exists; carriers such as glycols, if used, are declared separately on the label.
In plain English
A skin-conditioning extract made from the leaves of Tephrosia purpurea, a small legume (Fabaceae) that grows in warm regions. The leaves are steeped in a solvent such as water or alcohol and the liquid is concentrated, so it comes entirely from the plant.
CosIng definition: Tephrosia Purpurea Leaf Extract is the extract of the leavess of the Tephrosia purpurea, Fabaceae
