Clear shampoo and order of addition
Hello,
I have a few doubts regarding order of addition. Kindly try and explain them if you get time.1)I added 1 mL of citric acid to 30 mL of water and then added 0.6 grams of guar hydroxypropyltrimonium chloride. The resulting solution was really messy and GHTC gelatinises instantly . But when I add GHTC to water first and then add citric acid, I get a transparent solution. What could be the reason behind it?2)I am trying to make a clear shampoo and performed knockout experiments, and got to know that it’s difficult to solubilise CAPB and Coco DEA and they may be the reason why I am not getting a perfectly clear shampoo , can you suggest something to solve this issue?3) CAPB imparts a golden colour to the solution as well. I tried putting in more surfactant to remove it but it won’t go.4)I am using salt and GHTC as hydrophilic thickeners and Coco DEA as a hydrophobic thickener, I’ve read that using other hydrophilic thickeners other than PEG do not thicken the solution much, is it true?
