Cyclodextrin is a general term for cyclic oligosaccharides (cyclodextrins) biotechnologically derived from starch by enzymatic degradation with a CGT (Cyclodextrin Glucose Transferase enzyme). So, it is a versatile, natural, and biodegradable cosmetic ingredient derived from botanical raw materials.
Like dextrins and other oligosaccharides, cyclodextrins contain multiple OH groups in their molecular structure. These groups attract water molecules and exhibit excellent hydrating and skin conditioning properties. In addition, Cyclodextrin is a multifunctional ingredient for personal care applications that can act as an absorbent, chelating agent, and emollient, depending on the formulation type.
Moreover, Cyclodextrin is a perfect stabilizer for active ingredients in formulations, protecting them from oxidation and thermal degradation. It improves formulation texture and uniformity, acts as a solubilizer, and enhances penetration rates of larger molecule actives.
Thanks to its dual nature (hydrophilic and lipophilic), Cyclodextrin is also used in some liposomal delivery systems, where it encapsulates unstable active ingredients. Those delivery systems provide controlled-release of actives with enhanced bioavailability and functional activity.Cyclodextrin is a safe, naturally derived, and eco-friendly ingredient that is not irritating to the skin or eyes.
