Science
Mechanism of Action
This ingredient functions as an amphiphilic film-former, utilizing a silicone backbone to create a breathable, water-resistant shield. The polyglyceryl-7 segments ensure deep humectancy and effortless dispersion, while the oxyphenylpropyl groups increase the refractive index for a radiant finish and stabilize the lipid layers of the skin's surface.
Research
Clinical Evidence
High confidence1%
Key findings
- 01 Clinical data shows a 1.0% concentration reduces frizz volume by 50% in extreme (90%) humidity while maintaining 90% curl retention over 24 hours.
- 02 Studies indicate a significant reduction in structural breakage during thermal stress and enhanced color longevity in treated fibers at concentrations as low as 0.1%.
Transparency
Dusting Analysis
While effective for shine at low levels, clinical benefits for structure and anti-frizz require at least 1.0%. Formulas claiming 'shape memory' or 'heat protection' using less than 0.5% may be under-dosing for marketing purposes.
The Formula
Formulation
Stability
Exceptionally stable under high thermal conditions (up to 100°C), making it a gold standard for heat-styling protection. It is versatile enough for cold-process manufacturing and dual-phase dispersion.
Synergies
- Natural oils
- Humectants
- UV filters
Conflicts
- Strong oxidizing agents
- Highly acidic environments (pH < 3.0) which may compromise the polyglyceryl bonds
Safety
Safety Profile
