Protectalon -Viscoelastic- VSY-Biotechnology

7 different concentration Viscoelastic from biofermented Sodium Hyaluronate. 1%, 1,2%, 1,4%. 1.6%, 1,8%, 2%, 3%.  All but the 3% are Cohesive with medium to high Zero Shear Viscosity and regular high MW to ~3 miiion Dalton. However the 3% concentration has a much lower MW and low Zero Shear Viscosity, therfore it is classifien as Dispersive.
