Science
Mechanism of Action
This ingredient operates by exhibiting a hydrophobic effect, allowing it to bind effectively to the surface of bacterial and fungal cells and their membranes. This interaction disrupts cellular function, leading to microbial cell death and thereby inhibiting the growth of various pathogens within cosmetic products.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Isopropyl Benzoate as safe for use in cosmetic products. The European Union permits its use as a preservative in both leave-on and wash-off cosmetics, with a maximum concentration of 0.5%. While the FDA no longer authorizes its use as a synthetic flavoring substance, it remains regulated under FDA PART 172.515 for synthetic flavoring substances and adjuvants, and the JECFA found no safety concerns as a flavoring agent at current intake levels.
