PPG-25-Laureth-25

What is PPG-25-Laureth-25?

PPG-25-Laureth-25 is a synthetic non-ionic surfactant derived from lauryl alcohol ethoxylated with 25 ethylene oxide units and capped with polypropylene glycol chains. This structure provides a balanced hydrophilic-lipophilic profile, making it ideal for use in rinse-off cleansers, shampoos, body washes, and leave-on emulsions like lotions. In formulations, it functions by reducing surface tension at the oil-water interface, allowing stable blending of immiscible phases to form creamy textures. It also solubilizes lipophilic ingredients such as fragrances into aqueous systems and promotes lather formation during cleansing. Its mild nature supports clear, non-residue rinses, contributing to product efficacy across personal care categories without altering skin barrier integrity.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Facilitates stable oil-in-water emulsions for smooth, consistent lotion and cream textures.

Enhances cleansing by lowering surface tension to remove oils and impurities effectively.

Promotes foaming action in shampoos and washes for a satisfying lather experience.
