Cyclodextrin
What is Cyclodextrin?
Cyclodextrin is a ring-shaped molecule made of glucose units, produced through enzymatic processing of starch like corn or potato. Belonging to the family of cyclic oligosaccharides, it features a hydrophilic exterior and hydrophobic interior cavity. In cosmetics, it appears in cleansers, powders, deodorants, and emulsions. It works by forming inclusion complexes, trapping oily substances, odors, or unstable ingredients within its cavity to enhance solubility, reduce greasiness, and prevent degradation. As an absorbent, it mattifies skin by soaking up excess oils; as a chelating agent, it sequesters metal ions that could spoil products. This dual action supports clearer, more stable formulations without heavy residues.
