Pharma, Cosmetics | Intrinsic Viscosity Measurements of Sodium Hyaluronate according to European Pharmacopoeia
Sodium hyaluronate is an important raw material for pharmaceutical and medical applications. To ensure consistent quality and safe application it undergoes European Pharmacopoeia tests. Intrinsic viscosity measurement of sodium hyaluronate with Lovis is one of these tests.
Sodium hyaluronate is the sodium salt of hyaluronic acid and is naturally present in the human body. For medicinal applications, hyaluronic acid either has to be extracted from rooster combs or is synthesized by bacteria under lab conditions. Sodium hyaluronate can be classified into different grades and is widely used in several industries.
Tests required in EU Pharmacopoeia
The EU Pharmacopoeia is a collection of test methods for the identification and quality control of several pharmaceuticals/medicines. The qualitative and quantitative composition and the tests to be carried out on medicines, raw materials used in production, and on the intermediates of synthesis are described. All producers of medicines and/or substances for pharmaceutical use must therefore apply these quality standards in order to market their products.
Apart from other parameters, sodium hyaluronate must be tested for its intrinsic viscosity, which has to be stated additionally when labeling the substance.
Lovis microviscometer in pharmaceutical industry
Lovis is compliant with 21 CFR Part 11 and qualification documentation for regulated industries can be offered. In addition to dynamic and kinematic viscosity determination, Lovis offers an integrated polymer software for automatic calculation of polymer parameters such as intrinsic viscosity and molar mass.
