Without more information about the non-water soluble material, it is difficult to give you any specific details. The best I can offer is to try creating an emulsion or a suspension of the non-miscible components. Emulsions are probably the longest lasting option - salad dressing and whipped cream are great examples of very stable, long-lasting emulsions. You should be able to find some great literature on emulsion technology at your local public or university library, or on the internet. Good luck! Kieran
