Science
Mechanism of Action
This ingredient functions as a cationic polyelectrolyte, creating a substantive, bio-adhesive film on the stratum corneum that significantly reduces transepidermal water loss (TEWL). Its unique molecular structure allows it to sequester pro-inflammatory peptides like LL-37, effectively modulating the skin's inflammatory response, while its surface-active properties stabilize complex oil-in-water interfaces through increased interfacial viscoelasticity.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Demonstrated significant emulsion stabilization and film-forming substantive properties at concentrations as low as 0.01% to 0.5% in MDPI Polymers research.
- 02 Clinical utility in treating inflammatory conditions like rosacea by sequestering antimicrobial peptides, utilized in stable concentrations up to 25%.
Transparency
Dusting Analysis
Because it is highly effective for emulsion stabilization at very low levels (0.01%), it is rarely 'dusted' in the traditional sense; however, for therapeutic anti-inflammatory benefits in sensitive skin, concentrations should ideally reach 0.05% to 0.5%.
The Formula
Formulation
Stability
Maintains excellent stability in aqueous environments and enhances the delivery of co-actives by improving skin adhesion due to its cationic charge.
Synergies
- Aqueous active delivery systems
- Humectant boosters
- Biocompatible polymers
Conflicts
- Strongly anionic thickeners like Carbomer (can cause precipitation)
- High electrolyte concentrations (may diminish viscosity-building properties)
