How we scored it

Calcium salt of carrageenan (seaweed polysaccharide, natural) + calcium (natural mineral counter-ion) = 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

The calcium salt of carrageenan extracted from red seaweed, formed by ion exchange with a calcium source. No petrochemical route exists.

In plain English

A gum derived from seaweed that helps thicken and stabilise creams and lotions. This version is bound to calcium, a natural mineral.

CosIng definition: Carrageenan, calcium salt
