How we scored it
Glycerol (natural, 92 Da) + abietic acid / rosin acid (natural pine-resin diterpene, 302 Da); both natural building blocks → 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
Ester of glycerin with abietic acid (rosin), obtained from pine tree oleoresin or tall oil, a byproduct of kraft pulping. A natural, variable-composition resin-acid mixture rather than a single pure ester.
In plain English
A film-forming, tackifying ingredient made from glycerin and rosin, a resin tapped from pine trees. Used in cosmetics for its sticky, flexible film properties.
