Kao Corporation Develops PRM database and Odor Intensity Prediction Method


Koa Corporation’s Sensory Science Research Laboratory has developed a detailed database of 314 perfumery raw materials (PRMs) regularly used in fragrance creation.

The database has led to the development of a technological method where a prediction of odor intensity can be made based on the concentration of PRMs present in a gas sample.

Kao will utilize these findings to achieve more sophisticated control of odor intensity, such as diffusion and lasting scent, in order to develop more attractive fragrance products for consumers. The Corporation will continue to contribute to improving the environment by seeking to decrease greenhouse gases emitted during the process of fragrance production and transportation through more effective utilization of PRMs.
