How we scored it
Menthone (mint terpenoid, C10H18O, natural) + glycerin (C3H8O3, natural) condense with loss of H2O (uncounted). Both building blocks natural = 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
Made by condensing menthone (typically from cornmint/peppermint oil) with glycerin to form a cyclic acetal. Used as a natural-origin cooling agent without an added menthol odour.
In plain English
A cooling ingredient made by combining a mint-derived compound (menthone) with glycerin. Gives skin and mouth-care products a fresh, refreshing sensation without added scent.
