Science
Mechanism of Action
It functions primarily as a potent iron-chelating ligand. By binding to metal ions essential for microbial metabolism, it effectively starves bacteria and fungi, halting their growth cycle. Additionally, it inhibits specific enzymes like matrix metalloproteinases (MMPs), which may offer secondary benefits in protecting the skin's structural matrix.
Research
Clinical Evidence
High confidence0.15%
Key findings
- 01 Demonstrated a 99.99% reduction in pathogens including P. aeruginosa and A. brasiliensis in surfactant systems at 1.0% concentration.
- 02 A Human Repeated Insult Patch Test (HRIPT) involving 52 participants confirmed a concentration of 0.195% to be non-irritating and non-sensitizing.
- 03 Proven effective at 0.5% in eliminating mold and fungi in anionic surfactant formulations within a 14-day window.

Dusting Analysis
Because it is a functional preservative booster rather than an active treatment, 'dusting' is less relevant; however, concentrations below 0.05% typically indicate it is being used only as a secondary chelator rather than a primary microbial stabilizer.
The Formula
Formulation
Stability
Exceptionally heat stable up to 90°C for short durations. It is unique for remaining effective at a neutral pH (7.0), where most organic acids lose their potency.
Synergies
- Glycerin
- Caprylyl Glycol
- Propanediol
Conflicts
- Iron-rich clays (Bentonite, Kaolin)
- Residual iron ions (may cause an orange hue)
- Strong oxidizing agents
Safety
Safety Profile
While highly safe, avoid use on severely compromised or broken skin barriers to prevent potential increased penetration.
