Ethoxydiglycol

Description

Ethoxydiglycol is a versatile and widely used solvent in cosmetic and personal care formulations. This clear, colorless liquid is prized for its excellent solvency properties and ability to enhance the penetration of active ingredients through the skin barrier. Chemically, it belongs to the glycol ether family and is derived from ethylene glycol.

In skincare products, ethoxydiglycol serves multiple functions. It acts as a coupling agent, helping to blend water-soluble and oil-soluble ingredients, thus improving formula stability. Its low surface tension allows for better spreadability of products on the skin. Ethoxydiglycol is particularly effective in dissolving preservatives, fragrances, and active ingredients like retinol and salicylic acid.

While ethoxydiglycol can enhance skin penetration, it's generally considered safe for use in cosmetics when formulated properly. However, its penetration-enhancing properties necessitate careful consideration of other ingredients in the formulation. Typical concentration ranges in skincare products are between 1% and 5%, depending on the specific application and desired effects.
