Ethoxydiglycol

The High-Performance Solvent

Ethoxydiglycol is a powerful solvent and penetration aid used to dissolve stubborn actives and help carry them into the skin.

It solubilizes ingredients that resist water and oil alike, improves the delivery of actives, and leaves a light, non-greasy feel.

Benefits of Ethoxydiglycol

A powerful solvent that dissolves difficult actives and aids their delivery.

Strong Solvency: Dissolves actives that resist both water and oil.
Penetration Aid: Helps carry actives into the upper skin layers.
Light Feel: Leaves a clean, non-greasy finish.
Anti-Recrystallization: Helps keep dissolved actives in solution.
Versatile: Works in water- and oil-based systems.

How It Works

Ethoxydiglycol is a small, amphiphilic glycol ether whose balanced polarity lets it dissolve a wide range of actives, while temporarily loosening surface lipids to improve penetration of the ingredients it carries.

Formulating with Ethoxydiglycol

Ethoxydiglycol is used at low to moderate levels to dissolve and stabilize actives and enhance delivery; because it boosts penetration, confirm finished-product tolerance. Observe good manufacturing and preservation practice.

Safety Analysis

Ethoxydiglycol is well tolerated at cosmetic levels; as it enhances penetration, confirm overall formula tolerance. As always, substantiate the finished product’s safety (e.g. patch / HRIPT testing) in line with MoCRA requirements.
