DEA-MYRETH SULFATE.

Questionable / CLEANSING, FOAMING, SURFACTANT - CLEANSING

DEA-Myreth Sulfate is an anionic surfactant primarily employed for its cleansing and foaming capabilities in rinse-off cosmetic formulations. Its utilization is critically restricted due to the potential formation of N-nitroso compounds, despite regulatory bodies deeming it safe under specific formulation conditions.

Cleansing Foaming Emulsifying Surfactant

Science

Mechanism of Action

Functioning as an anionic surfactant, DEA-Myreth Sulfate reduces the surface tension between different phases, enabling the effective emulsification of oils and dirt for comprehensive skin cleansing. This action also promotes the generation of rich foam, while general DEA salts can further contribute to emulsion stabilization, viscosity modulation, and conditioning effects in formulations.

Stability

The primary stability concern revolves around preventing the formation of N-nitroso compounds (nitrosamines). Formulations containing DEA-Myreth Sulfate must be meticulously designed to avoid any N-nitrosating agents that could trigger this undesirable reaction.

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The CIR Expert Panel concluded that DEA-Myreth Sulfate is safe under conditions of use and concentration when formulated to be non-irritating, with the crucial caveat to avoid its use in products where N-nitroso compounds can form. The FDA has indicated that studies have not established a link between DEA and human cancer risk. However, it is noteworthy that DEA-Myreth Sulfate, among other DEA-related ingredients, is currently reported as not in widespread use within cosmetic formulations.

Verdict

Questionable

While regulatory bodies acknowledge its conditional safety, the critical risk of nitrosamine formation and its reported lack of current widespread use render DEA-Myreth Sulfate a questionable choice for precision skincare formulations.
