From journals , it was clear that soy bean lecithin is good in forming micelles that can be used to deliver hydrophobic drugs when administered as oral drug delivery. what would be the best soy bean lecithin system to form micelle to separate hydrophobic biopolymer from the solution, when I did create soy bean lecithin dissolved in chloroform that can be used to form micelles by cloud point extraction, the added chloroform readily forms a two phase, while those of alcohol and acetone interact with the water, making the system more hydrophilic that the cloud point is already above 80 degree Celsius.

Can some one suggest me what would be the best concentration and system to study soy bean lecithin micelle by cloud point extraction
