Please allow me to comment - try adding
Butylene Glycol is 5%, then use no more than heat. 60 degrees in a short time will help to dissolve a lot - but if you do not want to increase the amount of
Butylene Glycol try reducing
Glabridin 40% to 0.02% and then use Hot not more than 60 degrees in a short time to help melt it. - But if you don't want to use heat to melt. It may take a long time to process and use
Glabridin 40% at not high concentration - must be dissolved
Glabridin 40% in
Butylene Glycol until a clear yellow liquid. because if not completely dissolved It will become sediment in the recipe. Thank you very much.
