How we scored it
Cyclic glucose oligomer (C36H60O30) made from starch by enzymatic conversion; only native hydroxymethyl groups from glucose itself, no synthetic substituents — 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
Cyclodextrin is manufactured by treating plant starch (typically corn or potato) with a bacterial enzyme that cyclises it into ring-shaped sugar molecules. No petrochemical substituents are added to this unmodified form.
In plain English
A ring-shaped sugar molecule, made by enzymes acting on plant starch, that can trap and hold other ingredients like fragrance. It comes from starch, typically corn or potato.
