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.
