DEA-CETYL PHOSPHATE.

Avoid CAS 69331-39-1 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

DEA-CETYL PHOSPHATE is a versatile ingredient that acts primarily as a cleansing agent and an emulsifier. It efficiently aids in removing skin impurities while stabilizing oil-in-water formulations for a uniform product consistency.

Science

Mechanism of Action

This compound functions as an amphiphilic surfactant, reducing the surface tension within cosmetic preparations to ensure even distribution. Its dual hydrophilic and lipophilic nature allows it to form micelles in aqueous solutions, thereby facilitating the solubilization of both oils and active ingredients into a stable emulsion. Additionally, it serves to adjust pH, enhance product viscosity, generate foam, and improve the sensory feel and spreadability of formulations.

Stability

With both water-attracting and oil-attracting properties, DEA-CETYL PHOSPHATE is effective across various formulation types. Achieving optimal stability for formulations incorporating similar alkyl phosphates may require high-temperature processing, typically between 85-90°C.

Conflicts

  • Nitrosating agents (due to risk of harmful nitrosamine formation)
  • Cationic ingredients (inferred, as an anionic emulsifier)
  • Metal salts (inferred, as an anionic emulsifier)
  • Alkaline earth metals (inferred, as an anionic emulsifier)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

DEA-Cetyl Phosphate is a DEA-related compound. A 1998 National Toxicology Program (NTP) study observed an association between topical application of DEA and certain DEA-related ingredients with cancer in laboratory animals, potentially linked to residual DEA, though no direct link to human cancer was established. The FDA maintains that consumer concern regarding its use in cosmetics is unwarranted. However, this ingredient has been listed on California's Proposition 65 as a cancer-causing agent since 2012. Notably, it is also regulated and forbidden for use in cosmetic products within Europe due to concerns about the potential formation of harmful nitrosamines when formulated with nitrosating agents.

Our Assessment

Verdict

Avoid

Despite its diverse functional benefits in formulation, the significant safety concerns, including its prohibition in Europe and listing under California's Proposition 65, make this ingredient unsuitable for precision skincare.
