Science
Mechanism of Action
Operates as a breathable occlusive emollient by forming a micro-thin, non-greasy film over the stratum corneum. This physical barrier significantly reduces trans-epidermal water loss (TEWL) while its solvent properties ensure the uniform distribution of active molecules and UV filters across the skin's topography.

Key findings
- 01 A 12-week clinical assessment (NIH, 2019) demonstrated that a gel-matrix containing this ingredient improved surface hydration in 89.3% of participants and enhanced barrier function in 64.3% of cases.
- 02 Research published in SciELO (2017) identified a 3% concentration as an optimal vehicle for active delivery, maintaining elevated hydration levels for 5 hours post-application.

Dusting Analysis
Typically used as a structural or sensory component rather than a 'hero' active. However, inclusion below 0.5% may indicate it is being used merely for label claims or at levels too low to provide meaningful occlusive benefits.
The Formula
Formulation
Stability
Exhibits exceptional thermal stability up to 80°C and remains chemically inert across a wide pH spectrum. It is a core component of cold-process gelling systems like Sepigel 305.
Synergies
