Solubility: Miscible with water, alcohols, glycols, and many cosmetic solvents

Function: Solvent, penetration enhancer, carrier, formulation aid

Ethoxydiglycol is a versatile cosmetic solvent widely used to improve the solubility of difficult-to-dissolve ingredients while enhancing the delivery and performance of active compounds. It is commonly found in serums, toners, treatment products, haircare formulations, and professional cosmetic systems.

Supplied as a cosmetic raw material for formulation use.

What It Does

Ethoxydiglycol helps dissolve challenging cosmetic ingredients while supporting their uniform distribution throughout the formula. It is particularly valued for improving the delivery of active ingredients and enhancing the sensory profile of finished products without adding greasiness or stickiness.

• Provides a light, elegant skin feel.
• Useful in advanced treatment and performance formulations.

Typical Use Levels

• 1–5% — Solvent and formulation support
• 3–10% — Active delivery systems
• 5–20% — Difficult solubility applications

How to Incorporate

• Add directly to the water phase or solvent phase.
