Science
Mechanism of Action
As a cationic (positively charged) surfactant, it electrostatically anchors to the negatively charged proteins of the skin. Its amphiphilic structure reduces surface tension to emulsify oils and debris, while its ability to disrupt microbial lipid bilayers provides inherent antibacterial protection.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 A Human Repeat Insult Patch Test (HRIPT) involving 500+ participants confirmed no sensitization at 0.25% concentration.
- 02 Scientific assessments of leave-on facial applications at 0.5% demonstrated zero risk of irritation, remaining well below the cutaneous threshold of 960 µg/cm².
- 03 OECD TG 404 testing indicates that even in high concentrations, skin reactions are minimal and resolve within 48-72 hours.
Transparency
Dusting Analysis
Because it functions primarily as a preservative or conditioning agent, 'dusting' is rare; however, levels below 0.1% may be insufficient for functional antimicrobial activity or noticeable skin conditioning.
The Formula
Formulation
Stability
Maintains peak stability in acidic to neutral environments (pH 3.0–9.0). It is highly resilient in aqueous solutions.
Synergies
- Non-ionic surfactants
- Cationic conditioning polymers
- Glycerin
Conflicts
