HYDROXYPROPYL TETRAHYDROPYRANTRIOL
Pro-Xylane, aka Hydroxypropyl Tetrahydropyrantriol, is a patented product of L'ORÉAL Group, which has been proved to be capable of promoting the synthesis of GAGs, collagen Ⅳ and Ⅶ, producing the hyaluronic acid, and enhancing the dermo-epidermal junction. Now Pro-xylane is the ace material which is used widely in almost every brand of L'ORÉAL Group.
It is been proved by L'ORÉAL that only the (β,S) and (β,R) isomers of Hydroxypropyl Tetrahydropyrantriol have anti-aging biological activity. What’s more, L'ORÉAL has published a paper “Synthesis of Pro-XylaneTM: A new biologically active C-glycoside in aqueous media” in 2009 which claimed that the anti-aging biological activity of (β,S) Hydroxypropyl Tetrahydropyrantriol is superior than that of (β,R) Hydroxypropyl Tetrahydropyrantriol but still the latter has a certain anti-aging biological activity.
As the expiration of Pro-Xylane's patent in 2019, Meiaohuawei launched its own Hydroxypropyl Tetrahydropyrantriol and has branded it Meiliyin and Chaoyinmei. Meiliyin is pure (β,S) Hydroxypropyl Tetrahydropyrantriol and Chaoyinmei is a mixture of (β,S) and (β,R) Hydroxypropyl Tetrahydropyrantriol with a customizable (β,S)/(β,R) ratio. Meiliyin and Chaoyinmei are both 100% self manufactured by Meiaohuawei.
Here are some quality standards of Meiliyin and Chaoyinmei.
