Science
Mechanism of Action
It operates as an associative thickener, where its hydrophobic C12-16 chains aggregate in water to form a complex 3D physical network. This structure not only locks oil droplets in place to prevent separation but also deposits a breathable, non-tacky film on the skin that acts as a humectant reservoir and conditioning barrier.

Clinical Evidence
High confidence0.5%
Key findings
- 01 Concentrations above 0.1% establish a 3D associative network that significantly outperforms standard celluloses in preventing phase separation.
- 02 Technical evaluations at 0.2%–0.5% confirm a unique shear-thinning behavior that facilitates high spreadability and a fresh, non-sticky finish.

Dusting Analysis
Because this ingredient is functional rather than 'active,' it is rarely used for marketing claims alone. However, inclusion below 0.1% may be insufficient to provide the structural stability or the sensory 'water-break' benefits it is known for.
The Formula
Formulation
Stability
Exhibits exceptional stability across a broad pH spectrum and maintains viscosity independently of pH once hydrated. Its non-ionic nature makes it highly compatible with salts and electrolytes.
Synergies
- Electrolytes
- UV Filters
- Humectants
Conflicts
- Cellulase enzymes
- Strong oxidizing agents
Safety
Safety Profile
Classified as a high-molecular-weight polymer, it is too large to penetrate the skin barrier, making it inherently non-irritating and non-sensitizing.
