Science
Mechanism of Action
This ingredient functions through a 'host-guest' architecture, featuring a hydrophobic core that traps active molecules and a hydrophilic exterior for easy dispersion. The cross-linked structure acts as a controlled-release reservoir, slowly diffusing ingredients over time to maximize bioavailability while simultaneously reducing the irritation potential of aggressive actives.

Key findings
- 01 Research indicates that natural cyclodextrins are well-tolerated at concentrations up to 0.1% in human subjects, with general cosmetic safety established up to 5%.

Dusting Analysis
Because it is often used as a technical carrier rather than a primary active, brands may include it at trace levels (below 0.1%) simply to claim advanced 'encapsulation technology' without providing meaningful stabilization or time-release benefits.
The Formula
Formulation
Stability
Significantly improves the shelf-life of oxidation-prone ingredients like Vitamin C, Retinoids, and essential oils by protecting them from light and thermal degradation.
Synergies
- Ascorbic Acid
- Retinol
- Fragrance compounds
