The video shows a way to disperse Hyaluronic acid cosmetic grade 1.00% into deionised water. This Hyaluronic Acid is relatively medium molecular weight. Our Hyaluronic acid cosmetic grade (HACC) specifications are: - Transparency (0.1% aqueous solution): ≥99.5% - Appearence: White or approximate white powder - Sodium Hyaluronate ( Dry basis): 90-105% - Glucuronic acid: ≥44.0% - pH (0.1% aqueous solution): 6.0-7.5 - Molecular weight: (1.0-1.35)×Million Dalton - Protein: ≤0.1% - Loss on drying: ≤10.0% - Heavy metal (Pb): ≤20ppm - As: ≤2ppm - Bacterial count: ≤100cfu/g - Mold and Yeast: ≤10cfu/g - Pseudomonas aeruginosa: Negative - Staphylococcus aureus: Negative The product is made by bacterial fermentation process (Streptococcus Zooepidemicus). It has high purity, high transparency, and high heat stability. The whole process contains twice purification and extra after-treatment process. No animal origin material used in the process.
