Ceteth-20
Ingredient Info
Ceteth-20 is a gentle surfactant (cleaning and emulsifying agent) derived from cetyl alcohol and used to help mix water and oil-based ingredients in skincare formulas. It helps create stable, smooth textures and can improve how active ingredients penetrate the skin.
Benefits
- Helps stabilize emulsions and creates smooth, pleasant textures
- May enhance skin penetration of active ingredients by gently altering the skin's outer barrier
- Allows formulation of lightweight, easily absorbable products
- Can help reduce the amount of harsh surfactants needed in a formula
Potential concerns
- May cause irritation or sensitivity in people with very reactive or compromised skin
- Excessive use or high concentrations could potentially disrupt the skin barrier
Science: Research shows Ceteth-20 can form stable nanostructured delivery systems (microemulsions and liquid crystals) that safely enhance skin penetration of active ingredients. Studies demonstrate it acts as a skin permeation enhancer by temporarily altering lipid organization, with no cytotoxic effects observed in tested formulations, though data on long-term consumer use remains limited.
