Precisa MAS001 – Moisture Determination of Liquid Soap

Application Note: Moisture Determination of Liquid Soap

The moisture determination of liquid soap is essential to ensure a product of the highest quality. If the moisture content is too high or too low, this can result in a low quality product and wastage can occur. 
In this application note we determine the moisture of liquid soap using Precisa’s XM60/EM120 Halogen moisture analyser.

Maintaining optimal moisture levels during the production of soap is critical to achieving the highest quality product. When the moisture content becomes too high or too low, product quality becomes inferior and waste occurs. To accurately test and regulate moisture in your product, you need a top quality soap moisture analyser.

This information is intended as a guideline for development of a moisture analysis method and parameter setting. Materials vary throughout the world and we will be more than happy to test customers’ individual samples.
