Science
Mechanism of Action
By lowering the interfacial tension between aqueous and lipid phases, Ceteareth-23 enables the formation of stable emulsions. Its high HLB value of approximately 15.9 makes it particularly effective at creating light, water-based textures that can efficiently suspend oil-soluble actives and facilitate gentle cleansing by binding to surface debris.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Demonstrated minimal irritation potential in cumulative 4-day and 21-day patch testing, with no evidence of sensitization.
- 02 Clinical safety trials showed only minimal irritation following a single dermal exposure, confirming a high safety margin at upper usage levels.
- 03 Confirmed as a non-sensitizer in Repeat-Insult Patch Tests (RIPT), validating its suitability for leave-on facial applications.

Dusting Analysis
As a functional texture enhancer and emulsifier rather than a primary active, Ceteareth-23 is typically used at levels required for structural integrity (often 1-5%). It is rarely 'dusted' because its inclusion is determined by the formula's physical stability requirements rather than marketing claims.
The Formula
Formulation
Stability
Highly resilient across an expansive pH range and heat-stable, making it an ideal candidate for hot-process emulsification and protective colloid stabilization.

Safety
Safety Profile
While safe for general use, it should not be applied to severely damaged or burnt skin. Manufacturers must maintain 1,4-dioxane levels below 1 ppm to meet safety standards.
