Science
Mechanism of Action
This ingredient utilizes a dual-functional molecular structure, combining anionic and non-ionic groups to stabilize complex emulsions. On the skin, it forms a cohesive, semi-permeable film that significantly inhibits trans-epidermal water loss (TEWL) while optimizing the glide and delivery of active ingredients.
Research
Clinical Evidence
High confidence0.35%
Key findings
- 01 Safety assessments by the CIR Expert Panel confirmed that concentrations up to 39% in rinse-off products are non-sensitizing.
- 02 Ocular and dermal testing at 100% concentration demonstrated that the material is non-irritating to slightly irritating, proving a high degree of biocompatibility.
- 03 Technical patents indicate that concentrations as low as 0.3% effectively optimize viscosity and skin comfort in friction-heavy applications like shaving.
Transparency
Dusting Analysis
Because it is functional at very low levels (under 0.5%) for texture and stability, it is rarely 'dusted' for marketing purposes; its presence usually indicates a deliberate formulation choice for product performance.

Formulation
Stability
While chemically stable across a broad pH range of 3.0 to 11.0, its viscosity and integrity are best maintained within the skin-neutral range of 5.5 to 7.0.
