How we scored it

Mannuronic acid (seaweed-alginate derived, ~193 Da, natural) etherified to methylsilanetriol (organosilicon, ~77 Da, scored 0 by silicone convention); 193/270=0.71.
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

Mannuronic acid is derived from brown-seaweed alginate by hydrolysis, then reacted with a synthetic methylsilanetriol (organosilicon chemistry) to form the silanol ether/ester.

In plain English

A silicon-and-seaweed ingredient that helps skin hold moisture and reduces static in hair. It combines a sugar acid from seaweed with a small silicon-based molecule made through industrial chemistry.

CosIng definition: Methylsilanol Mannuronate is the ester of monomethylsilanol and oligomeric mannuronic acid. It conforms generally to the formula: (structure)
