A pharmaceutically acceptable emulsifier for preparing fat emulsions for intravenous injection comprising purified phospholipid of vegetable origin, containing less than 5% of glycolipid, and having a degree of hydrogenation of 30-50 as defined by the iodine number is prepared from vegetable phospholipid by a three-step procedure comprising (in any order) (1) isolation of a fraction containing phosphatidylcholine, (2) partial hydrogenation to produce the desired iodine value, and (3) removal of glycolipid. |
