Science
Mechanism of Action
By lowering the interfacial tension between oil and water, Ceteth-5 facilitates the formation of stable micelles. With a Hydrophilic-Lipophilic Balance (HLB) of approximately 10–12, it is specifically optimized for creating fluid oil-in-water (O/W) emulsions and solubilizing lipophilic debris during the cleansing process without disrupting the skin's lipid barrier.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical evaluations of Ceteth analogues demonstrate that concentrations up to 3.0% are non-irritating to healthy, intact skin barriers.
- 02 Safety data indicates that irritation potential is dose-dependent, with significant reactivity observed only when concentrations exceed the 5.0% threshold.

Dusting Analysis
As a functional emulsifier rather than a bioactive 'hero' ingredient, Ceteth-5 is rarely used for marketing claims; however, it must be present in sufficient quantities (typically >1%) to ensure emulsion stability and texture integrity.
The Formula
Formulation
Stability
Exhibits exceptional chemical resilience; remains stable in the presence of reactive agents like hydrogen peroxide. Its non-ionic nature ensures compatibility across a wide range of active ingredients.
Synergies
- Hydrophobic actives
- O/W emulsion systems
- Micellar cleansers
Conflicts
- Strong oxidizers
- Strong mineral acids
Safety
Safety Profile
Manufacturers must utilize vacuum stripping during production to ensure potential trace impurities like 1,4-dioxane remain below the safety threshold of 1 ppm.
