Is Chitosan Adipate natural?

Mostly. Chitosan derives from crustacean shells; adipic acid is almost entirely petrochemical, made from cyclohexane oxidation.

How we scored it

Assumed 1:1 salt pairing. Chitosan repeat=161.2 Da natural; adipic acid (petrochemical)=146.1 Da. 161.2/307.3=0.524->0.52.
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

Chitosan (deacetylated crustacean chitin) is paired as a salt with adipic acid, a petrochemical commodity chemical. A 1:1 molar pairing was assumed since exact stoichiometry is unspecified.

In plain English

A film-forming ingredient made by combining chitosan, from crustacean shells, with adipic acid, a petrochemical building block, to form a salt. Leaves a light conditioning film on skin or hair.

CosIng definition: Chitosan Adipate is the adipic acid salt of chitosan
