Science

Mechanism of Action

As a diethanolamide, Lanolinamide DEA functions primarily to modify the physical properties of a formulation. It acts as a surfactant to reduce surface tension, effectively boosts foam stability, and increases the product's overall viscosity. Additionally, it can impart conditioning benefits to the skin and hair.

Stability

No specific optimal pH range for Lanolinamide DEA stability was identified. However, for a related diethanolamide, Lauramide DEA, stability is noted between pH 9.0-11.0 for a 1% solution.

Conflicts

  • Avoid use in cosmetic products where N-nitroso compounds may form due to potential reactivity.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Unknown

The CIR Expert Panel deems Lanolinamide DEA safe when formulated to be nonirritating and when free Diethanolamine (DEA) levels remain below established safe limits. Crucially, it must not be incorporated into products where N-nitroso compounds could be generated.

Our Assessment

Verdict

Questionable

Lanolinamide DEA offers valuable formulation properties as a surfactant and viscosity enhancer, but its safety profile requires stringent formulation controls regarding free DEA levels and N-nitroso compound formation, making its inclusion questionable for a precision skincare brand focused on direct skin benefits without compromise.
