How we scored it
Plant material (flowers): whole plant matter, all plant-derived (n = 1), no added synthetic groups. Natural mass / total mass = 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
Dominant feedstock is cultivated pot marigold flower heads, dried and sometimes milled. No synthetic route exists.
In plain English
The flower heads of pot marigold (Calendula officinalis), usually dried and sometimes crushed, used in skin-care products as a skin-conditioning ingredient. It is plant material rather than a chemical, taken from the cultivated flower.
CosIng definition: Calendula Officinalis Flower is plant material derived from the flowers of the Calendula, Calendula officinalis L., Compositae
