SODIUM TRIDECETH SULFATE.

Valuable CAS 25446-78-0 / CLEANSING, FOAMING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sodium Trideceth Sulfate is an anionic surfactant primarily valued for its effective cleansing and foaming properties. It functions by reducing surface tension, enabling the efficient removal of oil- and water-based impurities from the skin and hair. This makes it a key component in rinse-off formulations designed for thorough purification.

cleansing emulsifying foaming surfactant

Science

Mechanism of Action

Operating as a surfactant, Sodium Trideceth Sulfate significantly lowers the interfacial tension between diverse product components, such as water and oils. This reduction in surface tension facilitates the emulsification of oil and dirt, allowing water to effectively mix with and lift these impurities. It concurrently acts as a foaming agent, producing a rich lather that aids in detaching and rinsing away accumulated dirt, sebum, and environmental contaminants from the skin's surface.

Safety Profile

CIR Status
Safe as used
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel concluded in 2010 that Sodium Trideceth Sulfate is safe for use in cosmetics and personal care products, provided it is formulated to be non-irritating. The U.S. Food and Drug Administration (FDA) has also noted that trace levels of 1,4-dioxane, a potential manufacturing byproduct, found in cosmetics do not present a hazard to consumers.
