Science
Mechanism of Action
As a high HLB (Hydrophilic-Lipophilic Balance) molecule, Ceteth-40 reduces interfacial tension to stabilize complex formulations. It functions as a penetration enhancer by temporarily reorganizing the lipid architecture of the stratum corneum, allowing larger or more polar active molecules to bypass the skin's natural barrier more efficiently.

Key findings
- 01 Skin permeation modeling indicates significant enhancement of active ingredient delivery at 5% concentrations over a 48-hour period.
- 02 Clinical evaluations at 0.2% confirm the ingredient's integrity as a non-irritating stabilizer in multi-phase gel systems.

Dusting Analysis
Because Ceteth-40 is effective as a stabilizer even at 0.2%, it is rarely 'dusted' for marketing purposes. Its presence usually indicates a functional necessity for the formulation's texture or delivery mechanism.
The Formula
Formulation
Stability
Highly resilient to electrolyte fluctuations and thermal stress; maintains an HLB value between 17 and 20. Exhibits excellent stability in non-ionic environments.
Synergies
- Active bio-actives requiring enhanced delivery
- Electrolyte-rich serums
Conflicts
- High concentrations of anionic surfactants
- Strong oxidizing agents
Safety
Safety Profile
Ensuring high purity is critical; Moumoujus standards require minimal residual 1,4-dioxane (typically below 1 ppm) through advanced purification techniques like vacuum stripping.
