A closer look at the new anti-aging star - Pro-Xylane (Part 2)
Release time:2025-07-31
The popularity of Pro-Xylane has skyrocketed. Research results, experiments, and market validation have shown its repair and anti-aging properties, proving that Pro-Xylane is indeed a good product!!!
In 2019, L'Oréal's patent expired, and various Pro-Xylane raw materials and products have become increasingly abundant in China.
More and more consumers have more opportunities to use products containing Pro-Xylane, and its effectiveness is increasingly recognized. 'Ingredient-focused' consumers are enthusiastically embracing Pro-Xylane, with sales and attention serving as the best testament to its reputation.
What is true Pro-Xylane?
The compound corresponding to Pro-Xylane is called Hydroxypropyl Tetrahydropyran Triol.
The molecular formula of Hydroxypropyl Tetrahydropyran Triol is C8H16O5. According to relevant literature, this product is composed of a pair of diastereomers.
Essentially, Pro-Xylane is a compound composed of two diastereomers in a certain proportion.
The structure of Hydroxypropyl Tetrahydropyran Triol
However, the quality of some domestically produced raw materials claiming to be "Pro-Xylane" is uneven, leading to widespread complaints in the industry.
For example, some use xylose as a substitute for Pro-Xylane; some discolor easily at high temperatures, resulting in dark color and strong odor; some products contain too many impurities, with low Pro-Xylane purity and content; and some products are indeed Hydroxypropyl Tetrahydropyran Triol, but only one isomer is present.
Now let's introduce the Proxylane from Zhuhai Bory Pharm Co., Ltd.
Name| BeriCos™ Pro-Xylane-POW
Appearance: White to off-white powder (pure product)
(ps: 30% concentration solution can be customized)
Purity: ≥98.5%
Configuration Ratio: S≥90%
Regarding Appearance and Configuration:
There are two types of pure Pro-Xylane products on the market: One is a paste-like liquid, and the other is a powder.
Pro-Xylane is a chiral compound with four different configurations: (β,S configuration, β,R configuration, α,S configuration, α,R configuration).
Currently, the Pro-Xylane sold on the market is mainly a mixture of β,S and β,R configurations, with two different appearances: paste-like liquid and powder.
The difference between the two is:
Paste-like liquid Proxylane: The ratio of S and R configurations is between 50%:50% and 70%:30%.
Powder Proxylane: The ratio of S and R configurations is 90%:10%.
Relevant literature indicates: According to the research data in L'Oréal's patent application, "New C-glycoside derivatives and their cosmetic uses," the higher the S configuration content, the better the activity and efficacy.
