I want it for hair or body shampoo ..when I mixed it wih water it takes about half hour.. maybe there is a better way to dissolve it. even I try NaCl solution but there isnt any change.

@bimsmide your active ingredients are SLES and SLS. others like betain are cosurfactant. however we have test for determining the amphoteric active.
in your soap we can have these tests:
1- determination of anionic active(titration with hyamine)
2- determination of amphoteric active (titration with hyamine)
3- pH test
3- salt content test( if u add NaCl)

@perry why confusing,it is clear that in liquid soap the active ingredient is anionic surfactant.

I think this proble has to do with the quality of your SLES.

The important factor in dissoving PVA in water is formation hydrogen bond. with increasing temprature some bonds are breaked and solubilzing decreased, so its better to disperse PVA in cold water and then heating it slowy.
