Laneth-10

What is Laneth-10?

Laneth-10 is a synthetic non-ionic surfactant created by ethoxylating lauryl alcohol—a fatty alcohol sourced from plant oils like coconut or palm—with ten molecules of ethylene oxide. This modification enhances its solubility in water and ability to interact with both oils and water. Commonly used in rinse-off products such as shampoos, shower gels, facial cleansers, and makeup removers, as well as leave-on items like lotions and creams. In formulations, it lowers surface tension to promote wetting and spreading, lifts away dirt, sebum, and residues during cleansing, and forms micellar structures for gentle dirt removal. As an emulsifier, it creates a stable interface between immiscible phases, preventing separation and ensuring uniform texture and consistent application.

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 thorough yet mild cleansing by reducing surface tension and enabling foam formation.

Stabilizes emulsions for smooth, even textures in creams and lotions.

Enhances solubility of other ingredients, improving overall formula performance.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Individuals seeking gentle, foaming cleansers for daily use.
Those with allergies to fatty alcohols or ethoxylated compounds.
People with normal to oily skin needing effective yet non-stripping surfactants.
People preferring strictly non-synthetic or PEG-free formulations.
Users of emulsified products like moisturizers desiring stable, spreadable textures.
Individuals sensitive to surfactants in high concentrations.

Safety Notes

  • Considered low hazard for cosmetic use with minimal comedogenic potential.
  • Typically exhibits low irritation in standard concentrations from reviewed assessments.
