1. Introduction of hyaluronic acid:oduction of hyaluronic acid:
Hyaluronic acid is a kind of macromolecular mucopolysaccharide with d-n-acetylglucosamine and d-glucuronic acid as structural units. Hyaluronic acid in the skin plays an important role in the metabolism of the epidermis.
2. Specification of hyaluronic acid powder
Product name | Hyaluronic acid | Specification | 98% |
CAS No. | 9004-61-9 | MW | 776.6486 |
EINECS | 232-678-0 | MF | (C14H20NNaO11)n |
3. Source of Hyaluronic acid:
The main extraction methods of hyaluronic acid include animal tissue extraction, microbial fermentation and chemical synthesis. Due to the extremely low extraction rate and complex separation process, most of the hyaluronic acids on the market are produced by microbial fermentation and chemical synthesis. Our company produces hyaluronic acid by microbial fermentation.
