How we scored it

Alginic acid backbone (natural polysaccharide, majority mass) grafted with carboxymethyl, theophylline and methylsilanol (all treated non-natural); estimated 75% natural, substitution degree undisclosed.
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 reacting alginic acid, extracted from brown seaweed, with a synthetic methylsilanol-carboxymethyl-theophylline conjugate. The exact substitution ratio is not disclosed by suppliers.

In plain English

A seaweed-derived polysaccharide modified with small amounts of synthetic silicone and plant-alkaloid-related compounds, used to help condition skin.
