Science
Mechanism of Action
As a surfactant, DEA-LAURETH SULFATE operates by effectively reducing the surface tension between ingredients. This action allows for improved emulsification of oils and dirt, thereby enhancing cleansing efficacy and promoting the formation of lather and foam in personal care products.

Formulation
Stability
This anionic surfactant is water-soluble, with its solutions typically exhibiting a pH below 7.0. It is crucial to avoid co-formulation with nitrosating agents due to a significant risk of forming carcinogenic N-nitrosamines. Additionally, it is incompatible with cationic surfactants.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated related sulfated ethoxylated alcohols, noting they are dermal and ocular irritants but not sensitizers, and are considered safe when formulated to be non-irritating. However, the diethanolamine (DEA) component of DEA-LAURETH SULFATE introduces a critical safety concern regarding the potential for carcinogenic N-nitrosamine formation if formulated alongside nitrosating agents. While a 1998 NTP study did not establish a direct link between DEA and human cancer risk, the recommendation remains to minimize the co-use of amines and nitrosating agents. There is no specific SCCS or direct FDA cosmetic ingredient status for DEA-LAURETH SULFATE.

Verdict
Due to its potential for medium irritancy and comedogenicity, alongside a significant safety restriction concerning the formation of carcinogenic nitrosamines when co-formulated with nitrosating agents, DEA-LAURETH SULFATE is not recommended for precision skincare applications.
