PANTHENYL ETHYL ETHER

Last update on May 26, 2026

Panthenyl Ethyl Ether is a stable, oil-soluble derivative of Panthenol (Provitamin B5). Unlike regular Panthenol, its ethyl ether form is more lipophilic, allowing better penetration into hair and skin. It is valued for its excellent moisturizing, conditioning, and strengthening properties. This ingredient is widely used in hair care (especially leave-in conditioners and serums) and skincare products to improve hydration, softness, and overall condition without the stickiness sometimes associated with water-soluble panthenol.
