Science
Mechanism of Action
This low-HLB silicone derivative functions by reducing interfacial tension to stabilize emulsions. It creates a breathable, non-occlusive barrier on the stratum corneum that significantly mitigates transepidermal water loss (TEWL) while optimizing the spreadability of UV filters and pigments.
Research
Clinical Evidence
High confidence2%
Key findings
- 01 Clinical instrumentation demonstrated a 68% increase in skin hydration within one hour of application, with barrier protection maintained for 24 hours.
- 02 Research indicates that concentrations between 0.5-5% enhance UV filter water resistance and boost SPF performance by ensuring a more uniform film formation.
Transparency
Dusting Analysis
While functional at low levels for emulsion stability, concentrations below 0.5% may fail to provide the documented skin-barrier and hydration benefits seen in clinical trials.
The Formula
Formulation
Stability
Highly stable within physiological pH ranges; however, exposure to extreme pH levels below 4.0 or above 9.0 can cause hydrolysis of the acetate linkage.
