Importance of the Cloud Point of surfactants

The Cloud Point of a solution corresponds to the temperature above which a sample becomes turbid. The Cloud Point is a reliable quality control parameter for water-soluble surfactants, for both emulsions and dispersions.

Cloud Point measurement principle

Cloud point determination of surfactants is typically performed with a 1% weight dilution of the water-soluble surfactant in water. The surfactant is transparent at the beginning of the experiment, and when the Cloud Point is reached, the solution becomes turbid. The change in turbidity is detected fully automatically using the MP80 Melting Point System. Duplicate Cloud Point measurements provide additional reliability of results and increase throughput.

With this application note, you will learn how to determine the Cloud Point of surfactants using METTLER TOLEDO’S Melting Point System MP80.
