Bose is a substance that does not exist in nature and is not naturally extracted. It is synthesized from xylose derivatives.
It is a unique xylose derivative. Most of the Bose is extracted from European beech trees because the raw material xylose for the synthesis of Bose comes from beech trees, and there are several chemical reactions behind it.
Its true face is a raw material group composed of "water + propylene glycol + hydroxypropyl tetrahydropyran triol", but among them, "hydroxypropyl tetrahydropyran triol" (that is, the name you can see from the composition list) is the leading one.
"Hydroxypropyl tetrahydropyran triol" was originally a xylose found by L'Oreal in beech, but beech trees were powerless to use it on a large scale and add it in a high concentration. But these small problems can not defeat L'Oreal Baba. They specially developed a set of synthesis technology, used xylose derivatives to synthesize the Bose we now use, and also specially registered its household registration and registered patent protection.
