1.Larger Cavity For Bulky Molecules: Gamma cyclodextrin (CAS 17465-86-0) has a wider cavity than its alpha and beta homologues, so it can form inclusion complexes with larger hydrophobic molecules that do not fit inside the smaller rings.
2.Food Flavour Encapsulation And Stabilisation: Used as a food ingredient it encapsulates lipophilic flavour and nutrient components, improving the stability of flavours, vitamins, pigments and unsaturated fats during storage and processing.
3.Cosmetic Actives In Aqueous Systems: In creams and gels it complexes hydrophobic molecules and solubilises them in aqueous matrices, helping protect botanical actives, antioxidants and light sensitive ingredients while limiting irritation potential.
4.Odour And Off Taste Masking: The cavity traps volatile and malodorous compounds, so it is used to mask unpleasant odours and off tastes and to hold volatile actives inside a formulation instead of letting them escape.
