Over the past 30 years, various kinds of lipid emulsions
have been used, such as ClinOleic (containing olive
and soybean oil), Intralipid (100% soybean oil), Liposyn
II (50% soybean oil, 50% safflower oil), Lipoven (containing
soybean oil), and MCT/LCT (medium-chain
triglycerides/long-chain triglycerides). Most of the conventional
emulsions derived from soybean oil contain a
high amount of omega-6 polyunsaturated fatty acids,
mainly linoleic acid, and low amounts of antioxidants
