Science
Mechanism of Action
This ingredient utilizes both liquid and solid alkyl pendant groups to act as a thixotropic agent; it liquefies under the shear of application to provide immediate 'slip' and 'cushion,' then rapidly reorganizes into a structured, non-tacky film. By lowering the surface tension of organic oils, it transforms heavy textures into elegant, non-greasy finishes while reinforcing the skin's moisture barrier.

Clinical Evidence

Key findings
- 01 Demonstrated ability to make natural oil-based formulas mimic the light, volatile texture of cyclosiloxanes at a 3% concentration.
- 02 Clinical evaluation at 1-3% shows significant SPF boosting effects by optimizing the uniformity and film integrity of UV filters.
Transparency
Dusting Analysis
Because it is often used as a texture modifier to improve the 'claim' of natural oils, it is frequently included at sub-functional levels (under 1%) where it fails to provide the necessary thixotropic structure or SPF-boosting benefits.
