Science
Mechanism of Action
This ingredient functions as a potent surfactant, significantly reducing the surface tension between water and oils on the skin and hair. This action allows it to encapsulate and suspend dirt, sebum, and dead skin cells, facilitating their effortless removal during rinsing. It also contributes to rich foam generation and aids in emulsifying components within a formulation.

Formulation
Stability
A 10% aqueous solution of Sodium Coceth Sulfate typically maintains a pH between 9.0 and 9.5. It exhibits high solubility in water, forming clear solutions up to 30%, and is also soluble in polar solvents such as ethanol and propylene glycol. Stability is preserved between 0°C and 50°C, with irreversible property changes occurring above 50°C.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed related ethoxylated alkyl sulfates (structurally similar to Sodium Coceth-30 Sulfate) as safe with the crucial caveat that they must be formulated to be non-irritating. While the potential for irritation exists, it is rarely observed in properly formulated products. These ingredients are also noted for low acute oral toxicity and have been found not to cause skin sensitization.
