Vitamin B5 Panthenyl Ethyl Ether (CAS 667-83-4) is the ethyl ether of panthenol, a lipophilic provitamin B5 derivative that appears as a clear to slightly yellowish liquid, penetrates lipid-rich skin and hair structures more readily than standard panthenol, and acts as a moisturizing and conditioning active in topical formulations. Supplied as a clear to slightly yellowish liquid, it has a density of 1.073 g/mL at 20 °C, boiling point 443.8 °C (predicted), and flash point 110 °C.
The ethyl ether modification of panthenol increases lipophilicity, enhancing penetration through lipid-rich skin and hair structures compared to standard panthenol. It functions primarily as a moisturising and conditioning active in topical cosmetic and pharmaceutical formulations.
