Description
Cyclodextrins (CDs) are cyclic oligosaccharides formed by α-1,4 glycosidic bonds, typically consisting of 6, 7, or 8 D-glucopyranose units, known as α-, β-, and γ-cyclodextrins, respectively. CDs feature a truncated cone-shaped cylindrical structure with a hydrophobic inner cavity, a hydrophilic outer surface, and localized chiral environments. Their cavities can encapsulate various organic and inorganic small molecules to form inclusion complexes, enhancing the stability and solubility of active ingredients.
Pterostilbene is a naturally derived stilbene compound found in Pterocarpus marsupium, a botanical species traditionally valued in Ayurvedic medicine. Rich in pterostilbene, Pterocarpus marsupium bark extract provides a powerful plant-derived active ingredient with excellent biological properties. Known for its high stability and multifunctional activity, pterostilbene has been widely explored in pharmaceutical, nutritional, and skincare applications, making it a promising botanical active for advanced cosmetic formulations.
