Science
Mechanism of Action
Operating via the formation of "inclusion complexes," Hydroxyethyl Cyclodextrin utilizes its hydrophilic exterior and hydrophobic interior to meticulously encapsulate water-insoluble ingredients. This not only dramatically elevates their solubility and stability within aqueous systems but also optimizes their absorption into the skin, enables a precise controlled release over an extended period, and shields sensitive actives from degradation due to light, heat, UV, and various chemicals. Furthermore, it adeptly reduces potential irritation associated with certain active compounds and effectively neutralizes unpleasant scents.

Stability
This cyclodextrin robustly enhances the stability of encapsulated hydrophobic compounds, offering critical protection against decomposition and oxidation induced by environmental factors such as light, heat, and UV radiation, as well as chemical degradation. Its encapsulating ability also significantly improves the overall compatibility of various ingredients within complex cosmetic formulations.
Synergies
- Hydrophobic active ingredients (e.g., retinoids, vitamins, essential oils) whose solubility, stability, or skin absorption needs enhancement.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has unequivocally established hydroxyethyl-β-cyclodextrin (He-β-CD) as a safe cosmetic ingredient. It is broadly considered non-irritating and safe for use within the recommended concentration range of 0.1% to 5%. While adverse reactions are exceedingly rare, mild irritation or dryness could potentially manifest at concentrations significantly exceeding this recommended range. No potential for dermal sensitization has been observed.
