This is what I did,

1. Dissolve the product in 100ml of hot water

2. Add 10g of sodium carbonate and dissolve

3. Pull with ethyl acetate 5x times (100ml each time)

4. Settle combined pulls for 24h in fridge and decant Amy coagulant/blobs/etc. Even if nothing is seen I recomend decanting for you incase some difficult to see stuff has stuck to the walls.

5. Dissolve in 5g of citric acid and rest

6. A dense white cloud followed a few hours later by white crystals should form. Filter and dry them. This is the final product (for me was fluffy needless)
