Questionable CAS 243133-69-9 / CLEANSING, SURFACTANT - CLEANSING

DEA-C12-13 Pareth-3 Sulfate is a synthetic surfactant primarily utilized for its cleansing efficacy in skincare formulations. It functions by reducing surface tension to facilitate the removal of impurities from the skin's surface.

Summary

Cleansing Agent Surfactant

Science

Mechanism of Action

As a surfactant and cleansing agent, DEA-C12-13 Pareth-3 Sulfate operates by lowering the surface tension of the stratum corneum, which aids in the emulsification and removal of dirt and impurities. Chemically, it is classified as a PEG sulfate ester and represents the diethanolamine salt of the sulfate ester of C12-13 Pareth-3.

The Cosmetic Ingredient Review (CIR) Expert Panel has determined this ingredient safe for use under specific restrictions. Crucially, it must not be incorporated into cosmetic products where N-nitroso compounds could be formed. The free diethanolamine (DEA) content within the ingredient must strictly not exceed 0.64%. While a 1998 study by the National Toxicology Program (NTP) did not establish a link between DEA and human cancer risk, some scientific literature indicates possible dangers.

Verdict

Questionable

While an effective cleansing surfactant, its use is restricted due to the potential formation of N-nitroso compounds in certain formulations and a maximum free DEA concentration limit of 0.64%, requiring meticulous formulation for precision skincare.
