Science
Mechanism of Action
As a cationic surfactant, it adsorbs to the negatively charged membranes of microorganisms. The molecule's alkyl chains penetrate and destabilize the lipid bilayer, causing protein denaturation and the leakage of cytoplasmic contents. Additionally, it neutralizes surface electrical charges on hair and skin to prevent static and improve manageability.
Research
Clinical Evidence
High confidence0.1%
Key findings
- 01 Demonstrated 0.12% concentration as a viable alternative to alcohol for reducing pathogenic Staphylococci with lower dermal irritation.
- 02 Identified a Minimum Bactericidal Concentration (MBC) of 0.5 ppm against oral bacteria, showing higher potency than the chloride form.
- 03 Proven virucidal efficacy at 0.1% to 0.2% against enveloped viruses like SARS-CoV-2 on non-porous surfaces.
Transparency
Dusting Analysis
Because regulatory bodies cap leave-on concentrations at 0.1%, levels between 0.05% and 0.1% are considered functionally active for preservation and conditioning rather than 'dusted' for marketing.
The Formula
Formulation
Stability
Exhibits exceptional thermal and chemical stability across a broad pH spectrum; however, it reaches peak photostability at a neutral pH of approximately 7.0.
Synergies
- Nonionic surfactants
- Cationic conditioning agents
Conflicts
- Anionic surfactants (e.g., Sodium Lauryl Sulfate)
- Soaps
- Nitrates
- Iodides
- Zinc oxide
- Aluminum
Safety
Safety Profile
Strictly limited to 0.1% in leave-on products by the CIR and SCCS. Concentrations exceeding 0.1% are classified as potential skin and ocular irritants. Rinse-off hair products may utilize up to 3%.
