Reg Dissolving GHPTC (guar hydroxypropyltrimonium chloride) in water
I Started working on a shampoo formula without sulphates. I planned to use GHPTC for its anti static/anti drying property. As a first step, I decided to dissolve it in water and keep a check on stability. I used 0.4% of GHPTC and dissolved in water using stick blender. I reduced the PH as well to PH 4 as previously mentioned in this forum. After adjusting PH to 4 and stick blending for few minutes, I noticed that the solution turned clear. However after 1 week, I noticed that GHPTC started separating out. I didn’t notice any specific layer of solution separating out, but I noticed that it started floating some on top and some on bottom. PFA images for the same. I noticed that the temperature here in India reduced drastically from a couple of days. Not sure if that also has any impact on this separation. Can any one please let me know on what might be the issue and how to resolve this? Thanks a lot for your support in this regard.
