Beta Cyclodextrin (CAS 7585-39-9) is a seven-unit cyclic oligosaccharide supplied as a white powder, used as a Pharma Grade carrier for molecular encapsulation that stabilizes volatile actives and converts liquid ingredients into free-flowing powders. In the cosmetic sector, it functions as a Technical Grade odor absorber and controlled-release agent for fragrances. Its crystalline structure allows for the protection of sensitive actives like Retinol or Vitamin E from oxidative and thermal degradation. The product offers superior purity levels and cost-effectiveness compared to other cyclodextrin variants. It is a critical component in modern drug delivery, enhancing the shelf-life stability of a wide range of pharmaceutical dosages.
