TSUYAHIME RICE BRAN EXTRACT™

Item listed in the “Japanese Standards of Quasi-drug Ingredients”

Skin beauty extract from the rice bran of Tsuyahime brand rice grown in Yamagata, Japan

TSUYAHIME RICE BRAN EXTRACT™ is an extract from the rice bran of Tsuyahime brand rice grown in Yamagata, Japan. It is extracted with 1,3 butylene-glycol aqueous solution.

Tsuyahime is a new branded rice variety developed by Yamagata Prefecture. Tsuyahime has inherited the genes of Kameno-o, a legendary rice from the Shonai region of Yamagata. Kameno-o has also given rise to quintessential Japanese rice brands such as Koshihikari and Sasanishiki.

TSUYAHIME RICE BRAN EXTRACT™ is extracted from the rice bran remaining after it is cold pressed without the use of organic solvents through a continuous high-pressure cold press system. This enables us to obtain an extract that is safe and has superior heat denaturation properties.
