Cyclodextrin

Cyclodextrin is a ring-shaped molecule made from glucose units, used in cosmetics to bind and stabilize other ingredients and to help control odor.

What it is

Cyclodextrin is a cyclic oligosaccharide derived from starch, with a structure that forms a hollow ring capable of holding guest molecules in its central cavity. This ability lets it encapsulate, stabilize, or trap volatile and odorous compounds, which is useful for managing fragrance and certain reactive ingredients. In cosmetics it can also help solubilize or stabilize otherwise difficult ingredients.

Safety & warnings

Cyclodextrin is generally well tolerated in cosmetic use. It is a carbohydrate-based ingredient with no notable allergen or comedogenicity concerns at typical use levels.

Origin & sourcing

Produced from starch (typically corn or other plant starch) through enzymatic conversion that links glucose units into a ring.
