The serum of bamboo extract for sensitive skin innovation by Associate Professor Dr Supakorn Boonyuen, Thammasat University, was presented at the 48th International Exhibition of Inventions Geneva special edition 2021: Inventions Geneva Evaluation Days Virtual Event, and it has won the silver award.
The research by Associate Professor Dr Supakorn Boonyuen applied chemical technologies to study and seek information in addition to processing bamboo leaves in order to share with the farmers of Sa Kaeo and nearby areas the technology used to harvest and extract a flavonoid from bamboo leaves to generate income for the community.
He discovered that the flavonoid found in bamboo leaves is isoorientin, which is largely presented in the Sang Mon Nuan Rachinee strain of bamboo. The harvest and extraction processes are uncomplicated and can be performed by the local farmers.
Bamboo leaves brought in for extraction must be the leaves that are still on the plant and not the ones fallen to the ground. After they are cut, they need to be washed and dried in a shaded area and an insect-free facility. Then, they are crushed before being extracted by a solvent which will eventually evaporated.
The extract obtained is tested for its quality by the Department of Chemistry, Faculty of Science and Technology, before it is delivered to the processing plant.
Isoorientin additives in products are classified as non-toxic to cells and are highly effective. Cosmetics that contain this flavonoid from bamboo leaves can reduce cell inflammation and prevent free radicals which are the cause of skin wrinkles.
The product has been approved and already obtained the FDA registrations. They are the “concentrated serum from bamboo leave extracted for natural moisturization and smoothening” with registration number 10-1-6200008553″ and a “special formula cleansing micellar with bamboo leave extracted for thorough cleaning without dry skin after use” with registration number 10-1-6200008316.
