General technical requirements and test methods». ... Thus the current top priorities include not only the task of standardizing the foam quantity measurement procedure but also the determination of foam quality (volume weight) that must be ...
Evaluating Shampoo Foam - Scientific Spectator®
WebExperimental Procedure The application of the t 1/2 parameter for metastable foams comparison can be time consuming. Lunkenheimera and Malysa (2003) proposed a parameter called R5 to examine the foam stability of the surfactant solutions. ... The half time decay (t 1/2) of foam column is the most common method used to test foam … WebA novel foam-based colorimetric alcohol sensor was developed for the detection of alcohol in saliva. Detection was based on the color change of a potassium dichromate-sulfuric acid solution absorbed by melamine foam. In the presence of alcohol, the orange colorimetric sensor changed color to brown, green and, ultimately, blue, depending on the … development team in scrum
