How we scored it
Steam distillate of myrtle leaves in water: water (n=1) plus trace plant volatiles (n=1); nothing added. 1.0 x 100% = 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 Myrtus communis leaf, steam-distilled with water to give a hydrosol. No alternative route exists; any added preservative would be declared separately.
In plain English
The water collected when myrtle leaves are steam-distilled, carrying trace aroma compounds from the plant. It is listed as a fragrance ingredient. It is made only from myrtle leaves and water.
CosIng definition: Myrtus Communis Water Extract is an aqueous solution of the steam distillate obtained from the leaves of the Myrtle, Myrtus communis L., Myrtaceae
