Normally high molecular weight hyaluronic acid / sodium hyaluronate means sodium hayluronate with molecular weight ≥1,800K Da. The corresponding intrinsic viscosity is no less than 2.7 m3/kg.
For medical grade & injection grade sodium hyaluronate, we always measure intrinsic viscosity (m3/kg) instead of molecular weight Da (Dalton).
High Molecular Weight Injection Grade Hyaluronic Acid / Sodium Hyaluronate: HA-EP3.0
High Molecular Weight Medical Grade Hyaluronic Acid / Sodium Hyaluronate: HA-E3.0
High Molecular Weight Cosmetics Grade Hyaluronic Acid / Sodium Hyaluronate: HAC-H
High Molecular Weight Food Grade Hyaluronic Acid / Sodium HyaluronateHAF-H
