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.
Questions everyone asks
What does cyclodextrin do in a formula?
Its ring-shaped structure can trap guest molecules, helping stabilize ingredients and control odor or fragrance release.
What is cyclodextrin made from?
It is made from plant starch, which is enzymatically converted into rings of glucose units.
