Conducting Preservation Efficacy Tests on All Our Developed Products

To deliver our products with safety and confidence, we implement a series of preservative tests on every product.
Our preservative test methods are based on Japanese Pharmacopoeia criteria and also feature a set of stricter internal standards that are implemented on each testing condition.
We also investigate the microorganisms that exist under a wide range of states, and use these results to develop novel preservatives that can be used in products in all types of conditions safely.
