SODIUM DECETH SULFATE.

Questionable / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sodium Deceth Sulfate is an anionic surfactant primarily recognized for its potent cleansing and foam-boosting properties. It functions by significantly reducing surface tension, enabling the effective removal of oils and impurities. This ingredient is extensively utilized in rinse-off formulations to enhance product performance.

Summary

Cleansing Surfactant Foam Boosting

Science

Mechanism of Action

This ingredient operates as an anionic surfactant, effectively lowering surface tension to facilitate the emulsification and subsequent removal of hydrophobic substances like oils and dirt from the skin or hair. Its amphiphilic nature allows it to interact with hydrophobic regions of proteins, potentially disrupting their structure and solubilizing membrane lipids, thereby enhancing its deep cleansing and foaming capabilities.

Safety Profile

CIR Status
Safe as used
Max tested
29%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Sodium Deceth Sulfate is safe at concentrations up to 29% within rinse-off products. However, specific hazard statements indicate its potential to cause skin irritation (H315) and serious eye damage (H318), particularly for individuals with sensitive skin. The FDA lists it as a food contact substance, though this has limited direct implications for topical skincare safety.

Verdict

Questionable

While deemed safe for rinse-off applications by the CIR, Sodium Deceth Sulfate's recognized potential for skin irritation and serious eye damage, coupled with a lack of specific skin efficacy data, renders its use questionable for precision skincare, especially for sensitive complexions.
