- Specific details on test material used for the study:
- Cocoyl proline is produced directly in water solution. In this test, cocoyl proline was tested in the commercialized form, so in aqueous solution.
This choice was taken considering that for surface tension, solids need to be dissolved in water before testing. Furthermore, it provides a better understanding on the properties of the substance in the form that will be in contact with final users
Water percentage in the sample varies between 30 and 50%.
