Cyclodextrin

Cyclodextrin · Beta-Cyclodextrin · Hydroxypropyl Cyclodextrin

A ring-shaped sugar molecule that traps small ingredients to stabilize them or trap odors.

What it does

Cyclodextrins are ring-shaped sugar molecules with a hollow center. The cavity can trap a small guest molecule, which is used to stabilize fragile or volatile ingredients, control their release, or capture odor molecules. It is a delivery-and-stability ingredient rather than a skin active.

Also known as

beta-cyclodextrin
