Guangyu Biotechnology's sodium hyaluronate has excellent stability; there is no significant difference in stability between different batches of the same molecular weight product. In a normal aqueous solution environment, after static placement for 3-5 days, the viscosity does not significantly decrease, indicating a stable slow-release process. Similar products on the market tend to experience a significant drop in viscosity under the same conditions, leading to unstable solutions.
Guangyu Biotechnology's sodium hyaluronate has high content, with glucuronic acid content consistently above 46%-47%, and sodium hyaluronate content ranging from 97%-99%. This far exceeds national standards and clearly surpasses other similar moisturizing products on the market, some of which may falsely claim higher contents.
Guangyu Biotechnology provides actual measured molecular weights for its sodium hyaluronate COA, allowing customers to make informed comparisons. Unlike some companies that only provide a range of molecular weights, this approach offers greater transparency and saves customers time, enhancing efficiency.
The pH of Guangyu Biotechnology's sodium hyaluronate is maintained between 6-7, with protein content below 0.05%, ensuring high stability and low protein levels. This maximizes customer safety by minimizing allergenic factors. In contrast, other similar products often have excessively high pH levels and excessive protein content, leading to frequent allergic reactions.
