other● Benefits
Cyclodextrin functions as a chelating agent, helping to bind and neutralize metal ions that could destabilize formulations, and as an absorbent/mattifier to help reduce excess sebum or surface shine. Its hollow, cage-like molecular structure is also widely used in formulation chemistry to encapsulate and stabilize other active ingredients.
