Isolaureth-6

What is Isolaureth-6?

Isolaureth-6 is a synthetic non-ionic surfactant from the alcohol ethoxylate family. It forms by attaching six ethylene oxide molecules to isolauryl alcohol, a branched-chain fatty alcohol sourced from petrochemical processes. This structure features a water-repelling alkyl chain and water-attracting polyether head, allowing it to bridge oil and water. Primarily used in rinse-off cosmetics like shampoos, shower gels, and facial cleansers, it acts as a surfactant to generate foam and remove impurities by lowering surface tension. As an emulsifier, it stabilizes mixtures of immiscible ingredients for uniform textures. Its mild emollient nature enhances slip and softness during use, making it suitable for daily cleansing formulations without residue buildup.

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.
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.

Benefits

Enables effective dirt and oil removal through foaming action in cleansers.

Supports stable blending of ingredients for consistent product feel.

Adds a smoothing touch to skin during washing routines.
