I would like to measure the foam height and stability of surfactant solution. Is there any tailor made instrument to do that? - Thanks in advance :)
If you only want to measure the height of foam to evaluate the stability, I recommend that a simple glass tube equipped with a porous slica. To generate the same height of foam, blowing the gas with a constant rate through the silica to the aqueous solution of surfactant. Then collecting the height of foam according to the time.
Specifically for shampoos-foam height & stability are assessed by a standard apparatus known as Ross Miles Column-which more or less uses the principle mentioned above by Hu.
No Ross Miles generates the foam a different way. A defined volume of solution (different dilutions) is poured from a defined height into a graduated cylinder. You measure the height or volume of foam generated and its decay over time.
Foam testing should be close to the desired application.
A simple test could be dropping an Aspirin or similar tablet into a solution in a graduated cylinder.
Yes, I agree with Titus. Thanks.
Based on final application-the test has to be developed. What is the application Abhinav is trying to use? Shampoo, Shaving product or Detergent, Aerosol foam product? Or Is it in some reaction?
Hi all, I am trying to measure the foam of surfactant solutions.
