Science
Mechanism of Action
Functions as a lightweight emollient and solvent that reduces formula surface tension for superior pigment and UV filter dispersion. Upon application, it evaporates from the skin surface—mirroring the behavior of D5 silicones—to provide a silky glide while remaining on the surface without penetrating the stratum corneum.

Key findings
- 01 Comparative instrumental and panel testing confirmed that C9-12 Isoalkanes provide a sensory 'silky' glide and volatility profile identical to cyclopentasiloxane (D5).
- 02 Patent data indicates that concentrations between 4-8% are optimal for stabilizing oil phases in bi-phase cleansers while ensuring rapid, residue-free evaporation.

Dusting Analysis
As a functional solvent and texture enhancer, it is rarely 'dusted' for marketing purposes; its presence at lower concentrations is usually sufficient to modify the rheology and spreadability of a formula.
