What is Ceteareth-12?

Ceteareth-12 is a synthetic ingredient derived from cetearyl alcohol, a blend of cetyl and stearyl alcohols sourced from plant or animal fats, reacted with ethylene oxide to form a polyethylene glycol ether. This chemical modification creates a molecule with a hydrophobic fatty alcohol chain and hydrophilic ethoxylate groups, making it amphiphilic. In cosmetics, it belongs to the surfactant and emulsifier category, commonly used in lotions, creams, shampoos, and body washes. It functions by reducing surface tension between oil and water phases, forming stable micelles or interfacial films that prevent separation and ensure even distribution of ingredients. This enables the creation of lightweight emulsions with creamy consistency, aiding in product spreadability and rinse-off performance without stripping skin's natural moisture barrier.

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

Provides a softening effect through stable emulsions that lock in hydration.

Supports gentle cleansing in washes by enabling effective foaming and rinsing.

Enhances product texture for smooth application in creams and lotions.

Who May Benefit Who Should Avoid
Individuals with normal to dry skin seeking creamy moisturizers.
Those with known sensitivity to ethoxylated ingredients.
People using daily cleansers needing mild surfactant action.
People preferring completely natural or preservative-free formulations.
Users preferring stable, non-separating emulsion-based products.
Individuals avoiding potential trace impurities in surfactants.

Safety Notes

  • Assessed as safe for cosmetic use by expert reviews with low concern ratings.
  • Non-comedogenic, unlikely to clog pores at typical concentrations.
