Science
Mechanism of Action
Benzyl Glycol facilitates skin hydration by drawing moisture into the stratum corneum and simultaneously increases the fluidity of microbial cell membranes. This dual action allows it to destabilize mold and yeast while acting as a penetration enhancer that accelerates the cellular accumulation of other active compounds.

Key findings
- 01 Demonstrated broad-spectrum antimicrobial synergy when paired with other glycols, allowing for a reduction in traditional chemical preservatives (Patent KR20160094524A).
- 02 Identified as a potent penetration booster at 1.0% concentration by enhancing membrane fluidization and active ingredient uptake (ResearchGate data).
Transparency
Dusting Analysis
Because it functions primarily as a preservative booster and solvent, concentrations below 0.5% are often insufficient for efficacy. In precision formulations, it should be present at 0.5%–2.0% to provide meaningful humectancy and antimicrobial support.
The Formula
Formulation
Stability
Displays exceptional chemical stability across an expansive pH range. It is significantly more stable in alkaline conditions (above pH 5.5) compared to Benzyl Alcohol, making it the preferred choice for high-pH formulations.
