How we scored it
Plant extract: all constituents derive from plant biomass (n=1); extraction solvent leaves no mass. 1.00 / 1.00 = 1.00.
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
Harvested Lavandula spica flowers, leaves and stems are extracted with water, ethanol or glycerin-type solvents, then filtered. No synthetic route exists; a carrier such as propylene glycol is a separate INCI line and is not scored here.
In plain English
A skin-conditioning ingredient extracted from the flowers, leaves and stems of Lavandula spica, an older botanical name applied to lavender. It is a mixture of plant compounds, and its makeup depends on the solvent and supplier.
CosIng definition: Lavandula Spica Flower/Leaf/Stem Extract is an extract of the flowers, leaves and stems of the Spikenard, Lavandula spica, Labiatae
