Isodeceth-6

What is Isodeceth-6?

Isodeceth-6 is a synthetic non-ionic surfactant produced by reacting isodecanol, a branched alcohol from petroleum sources, with six molecules of ethylene oxide. This ethoxylation process yields a hydrophilic compound effective at bridging oil and water phases in cosmetic formulations. Primarily used in rinse-off cleansers like shampoos and body washes, it also appears in leave-on products such as lotions and makeup removers. Functionally, it reduces interfacial tension to form micelles that encapsulate impurities for removal, while enabling stable emulsions with smooth textures. Its balanced hydrophile-lipophile properties support foaming and solubilizing actions, contributing to product efficacy across various personal care categories.

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

Gentle surface tension reduction for effective dirt and oil removal during cleansing.

Stabilizes oil-in-water emulsions, ensuring even distribution and consistent feel in creams.

Supports non-comedogenic formulations, minimizing pore blockage potential.
