Dusting Analysis

Not commonly dusted

Due to its oil-soluble nature and low bioavailability, Zeaxanthin requires specific delivery systems like nanoemulsions for effective topical application, making 'dusting' ineffective.

Stability

Zeaxanthin exhibits good stability but its oil-solubility necessitates nanoemulsions or similar delivery systems to enhance bioavailability and stability in formulations. Optimal pH for topical serums is 4-6.

Conflicts

  • Water-based products (without appropriate delivery systems) may not effectively deliver the ingredient due to its oil-soluble nature.
