Sodium Hyaluronate (CAS 9067-32-7)

Application and positioning

The sodium salt of hyaluronic acid, supplied in defined molecular weight ranges because the molecular weight sets the feel and the film. Cosmetic grade is specified on molecular weight, on protein and nucleic acid residues, and on microbial limits. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the purity and microbiological documentation cosmetic formulators require.
