Oleth-2

Benefits
Softening

What is Oleth-2?

Oleth-2 is a non-ionic surfactant produced by ethoxylating oleyl alcohol, a fatty alcohol sourced from vegetable oils, with two units of ethylene oxide. This creates a water-soluble compound ideal for cosmetic applications in categories like moisturizers, shampoos, body washes, and makeup removers. It functions primarily by reducing surface tension at the oil-water interface, enabling the creation of stable emulsions that blend immiscible ingredients for uniform texture and spreadability. As a fragrance solubilizer, it disperses scents evenly without separation, and its surfactant properties support gentle foaming and cleansing by lifting dirt and oils. This versatile agent enhances product performance without heavy residue, fitting various formulation needs.
