I tried to create a suspension of EDTA powder in Glycerin with 1:1 ratio. I keep facing problem of EDTA sedimentation. I've tried other ratios also but this was the only one which formed least amount of sediment.
When I used coarse powder, the sediment formed within 24 hours but when finely ground powder was used, the same occurred but after 3 days. I even tried heating the powder & glycerin together on low & medium heat but EDTA sediment still forms but with varied time.
I'd like that the suspension remain consistent irrespective of how much time goes by. I read on the internet that anti-settling agents (like xanthan gum & microfibrillated cellulose) can be used but I haven't tried that yet.
Can anyone please help & guide me?
