Moisture content is an important parameter in aerosols and creams. Substances such as sunscreen, muscle ache creams, and anti-fungal treatments are considered to be over-the-counter medicines; therefore the composition of these substances is closely monitored. The composition of each batch must match what is registered according to Australian regulatory guidelines for OTC medicines.

Application:

An aerosol and cream manufacturer was setting up a new quality assurance lab to perform quality checks on their aerosols and creams. Because of the regulations, they needed to monitor the moisture content of their products. Research and development laboratory was also interested in measuring the water content of their samples at different stages in the formulation process.
