Science
Mechanism of Action
This ingredient functions by reducing electrostatic charges on hair and skin, acting as an antistatic agent. As a surfactant, it facilitates the removal of impurities like dirt and oil, simultaneously improving foam volume, structure, and durability. Additionally, DEA-Myristate can modify product thickness, acting as a viscosity controlling agent to either increase or decrease the consistency of a formulation.

Stability
DEA-Myristate is a white to off-white waxy solid with a melting range between 40°C and 54°C. Optimal stability for a 1% aqueous dispersion is observed within a pH range of 9.5 to 10.5.

Safety
Safety Profile
The CIR Expert Panel deems Myristamide DEA safe for rinse-off products. In leave-on applications, its use is restricted to concentrations that limit the release of free ethanolamines to a maximum of 5%, with a general maximum use concentration of 40% for related amides. A primary safety concern is the potential for diethanolamine (DEA) to form carcinogenic nitrosamine compounds, leading to a caution against its use in formulations susceptible to such reactions. California's Proposition 65 has listed DEA as a cancer-causing agent since 2012, and the US EPA classifies DEA as a hazardous air pollutant. The SCCS also approves its use under specific restrictions, which may include purity and concentration criteria.

Verdict
Despite its functional benefits in formulations, the significant safety concerns regarding potential nitrosamine formation, California's Proposition 65 listing, and EPA hazardous air pollutant classification preclude its use in precision skincare.
