Science
Mechanism of Action
This compound primarily functions as a fragrance enhancer, imparting a pleasant scent to cosmetic products. As a preservative, it actively inhibits the growth of bacteria, yeasts, and molds, thereby extending product shelf-life and ensuring microbial stability. Furthermore, Methyl Benzoate serves as an effective solvent, dissolving various ingredients within a formulation, and provides a skin conditioning effect by contributing emollient properties that soften and smooth the epidermal layer.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Methyl Benzoate as safe for use in cosmetic products. The European Union permits its use as a preservative in cosmetics at concentrations up to 0.5%. While extensively reviewed as a benzoic acid ester, a specific SCCS opinion directly addressing Methyl Benzoate was not readily available in the provided research, with primary references often pertaining to related compounds.
