Sodium Hyaluronate powder is used for cosmetic addition and oral administration, and the two specifications of the process control the same focus, the main differences are:
1, Heavy Metal Control
The control of heavy metals at the cosmetic level is less than 20 ppm.
Food level request is less than 10 ppm.
2, Microbiology Control
Cosmetics grade hyaluronic acid powder Microbiology control mainly focuses on copper-green pseudomonas and Staphylococcus aureus.
Food grade mainly control E. coli and salmonella.
3, Cosmetics grade pay more attention to the appearance of product solution control, such as light transmission and absorbance requirements are relatively high.
The food grade has a wide range of control because it has less impact on the appearance of the end product.
4, Food-grade product saccumulation density requirements are more stringent, density is too large or too small will affect the finished product load.
Cosmetic level requires less accumulation density, and density has less effect on end products.
Pharmaceutical grade hyaluronic acid in the production, product technical indicators and other aspects have higher requirements, pharmaceutical-grade hyaluronic acid raw materials for purity requirements are higher, must pass the approval process of raw materials and auxiliary drugs, it has more stringent requirements for nucleic acids, endotoxins and other impurities control.
Recommended Additions:
Food-grade consumption of 200mg/day
Cosmetic-grade recommended additions: 0.05% to 0.5%
