Hi Microformulation, 

I’ve kept the gluconolactone very low at 0.3%, potassium sorbate also at 0.3% and allantoin at 0.5%. Some of the allantoin settles at the bottom as a white powder. However, the crystallization is a new experience since the addition of gluconolactone (which I had not been using before).

Thank you
