Hi Everyone. Can Creep Test help me to study the product's 'stringy' flow??

Hi Everyone. I am working on a gel based product put in a tube. When tube is pressed the sample flows easily out of the orifice. But once we stop pressing the tube, the sample still gives stringy...

I am looking for dyes/any material which can give visible color change when surfactant is added to the water. Any idea?

Hi. The objective is to demonstrate to students that surfactant solutions can solubilize dirt/hydrophobic substances. So, I am looking for dyes/any material which can show visible change in color...

If a fraction of polymer surfactants in selective solvent gets attached to a solid surface, will this affect aggregation number of the surfactants?

Can conformational/translational/rotational freedom of those surfactants attached to solid surface be reduced? If so will they affect the micellization process?
