How we scored it
Plant lignan (C20H22O6, 358 Da); cosmetic-grade material is extracted from lignan-rich plants (e.g. flaxseed/knotwood); all atoms natural, no petrochemical fragment identified.
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
Matairesinol for cosmetic use is obtained by extraction from lignan-rich plant sources such as flaxseed or knotwood. A chemical total-synthesis route exists but is not commercially significant.
In plain English
A naturally occurring plant compound (a lignan), typically obtained from sources such as flaxseed. Used as a skin-softening emollient.
CosIng definition: Matairesinol is the organic compound that conforms to the formula:
Structure
(3R,4R)-3,4-bis[(4-hydroxy-3-methoxyphenyl)methyl]oxolan-2-one
