How we scored it

Fully synthetic carbamate preservative built from petrochemical butanol, propargyl alcohol and iodine chemistry; 0.0.
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.

How it’s made

Alcohol + isocyanate (carbamate), then alkyne iodination. Each curved arrow moves one electron pair, and the film ends on the score above.

Where it comes from

Manufactured by reacting butyl carbamate with an iodinated propargyl intermediate, both from petrochemical/synthetic chemistry. There is no natural-origin production route.

In plain English

A fully synthetic preservative molecule. Used in small amounts to stop bacteria, mould and yeast growing in a product.
