Laureth-6

What is Laureth-6?

Laureth-6 is a synthetic non-ionic surfactant derived from lauryl alcohol, a C12 fatty alcohol, ethoxylated with six units of ethylene oxide. This chemical modification enhances its water solubility and ability to interact with both oil and water phases. In cosmetics, it appears in shampoos, body washes, facial cleansers, lotions, and creams. As a surfactant, it reduces surface tension between liquids and solids, enabling dirt and oil removal while promoting foam formation. Its emulsifying properties create a stable film at oil-water interfaces, preventing separation in emulsions for smooth, consistent textures. This makes it valuable in rinse-off and leave-on products, contributing to effective yet mild cleansing without harshness associated with some anionic surfactants.

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

Supports gentle cleansing by removing oils and impurities while forming stable foam.

Helps blend oil and water in formulations for even, non-separating textures.

Non-comedogenic, suitable for formulas targeting clearer pores.

Who It's For

Who May Benefit Who Should Avoid
Users of daily cleansers and shampoos seeking mild foaming action.
Those with known sensitivity to ethoxylated compounds.
Individuals with normal to oily skin preferring non-pore-clogging ingredients.
Individuals experiencing irritation from similar surfactants.
People using emulsified products like lotions for consistent application.
People preferring completely natural or sulfate-free alternatives.

Safety Notes

  • Rated low to moderate concern by safety databases, safe for typical cosmetic use.
  • Non-comedogenic with no pore-clogging potential.
