PANTHENYL ETHYL ETHER.

Insufficient Data CAS 667-83-4 / ANTISTATIC, HAIR CONDITIONING

Panthenyl Ethyl Ether is a functional derivative designed for enhanced delivery of Vitamin B5 to skin and hair. Upon absorption, it converts into pantothenic acid, a critical nutrient that supports various cellular metabolic processes, contributing to overall dermal and follicular health.

Summary

antistatic hair conditioning moisturizing skin barrier support wound healing anti-inflammatory fibroblast stimulation

Science

Mechanism of Action

This ether rapidly penetrates the skin, where it undergoes enzymatic hydrolysis within cells, yielding pantothenic acid (Vitamin B5). Pantothenic acid is a crucial constituent of Coenzyme A, a vital participant in metabolic pathways. This mechanism bolsters skin barrier function, accelerates wound healing, modulates inflammatory responses, stimulates fibroblast proliferation, and upregulates key cytokines such as IL-6 and CXCL1.

Stability

Panthenyl Ethyl Ether exhibits stability in neutral to slightly acidic aqueous solutions and is relatively resistant to oxygen and light. However, it is susceptible to hydrolytic cleavage in strongly acidic or alkaline environments. Elevated temperatures above 70-75°C can induce degradation and racemization.

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The CIR Expert Panel issued an 'Insufficient Data Announcement' in 2017, requesting further data concerning its manufacturing, impurities, sensitization potential, and chronic toxicity. While its related compounds, Panthenol and Pantothenic Acid, have established safety profiles, a specific safety determination for Panthenyl Ethyl Ether is pending the submission of additional research. It is listed within the FDA Global Substance Registration System.

Verdict

Insufficient Data

Panthenyl Ethyl Ether demonstrates a clear mechanism for enhancing skin and hair health through its conversion to Vitamin B5, yet a comprehensive safety determination by regulatory bodies awaits further specific toxicological and sensitization data.
