When a crystalline substance – such as an active pharmaceutical ingredient or an excipient – comes into contact with water, various types of interactions are possible. For the design of a dehydration process, it is therefore important to know the thermal properties of the particular sample. Thermogravimetric analysis in combination with kinetic evaluation helps determine this data and significantly reduce the time to develop a suitable temperature program.
Magnesium stearate is one of the most frequently used pharmaceutical excipients. Learn more about its hydration state and how it can be made visible.
