Science
Mechanism of Action
This ingredient operates through its low surface tension and non-polar structure, allowing it to dissolve and uniformly distribute pigments and UV filters. On the skin, it forms a breathable, non-greasy occlusive film that significantly reduces Transepidermal Water Loss (TEWL) without the heavy feel associated with traditional oils.
Research
Clinical Evidence
High confidence20%
Key findings
- 01 Clinical assessments demonstrate that concentrations between 15-20% are optimal for the uniform dispersion of organic UV filters like Avobenzone.
- 02 Human Repeat Insult Patch Tests (HRIPT) involving concentrations up to 90% confirm the ingredient is non-sensitizing and non-irritating to the human skin barrier.

Dusting Analysis
As a functional solvent and texture enhancer, C9-16 Isoparaffin is rarely 'dusted' for marketing purposes; it is typically used at significant levels to ensure the structural integrity and application performance of the product.
The Formula
Formulation
Stability
Highly chemically inert; exhibits exceptional resistance to oxidation, hydrolysis, and extreme pH fluctuations, making it ideal for anhydrous and W/O systems.
