Science
Mechanism of Action
It utilizes two distinct polysaccharide fractions—water-soluble tragacanthin and water-swellable bassorin—to form a flexible, breathable film on the stratum corneum. This barrier limits transepidermal water loss (TEWL) while its anionic structure stabilizes emulsions by increasing aqueous viscosity and preventing oil droplet coalescence.
Research
Clinical Evidence
High confidence6%
Key findings
- 01 Comparative research indicates that a 6% concentration optimizes wound closure and epithelial repair efficiency.
- 02 Human clinical safety trials confirm that applications up to 10% are non-phototoxic and non-reactive.
- 03 Dermal assessments at 1.5% demonstrate zero sensitization or irritation in human subjects.
Transparency
Dusting Analysis
While often used at low levels strictly for stabilization, concentrations below 1.5% may fail to provide the clinically documented film-forming and skin-soothing benefits.
The Formula
Formulation
Stability
Highly resilient in acidic environments down to pH 2.0; reaches peak viscosity between pH 5.0 and 6.0. Requires a 24-hour hydration period for full structural development.
