Liposyn II (intravenous fat emulsion) 10% contains 5% safflower oil, 5% soybean oil, up to 1.2% egg phosphatides added as an emulsifier and 2.5% glycerin in water for injection. May contain sodium hydroxide for pH adjustment. pH 8.0 (6.0 — 9.0). Liposyn II (intravenous fat emulsion) 10% has an osmolarity of 276 mOsmol/liter (actual). The total caloric value of Liposyn II (intravenous fat emulsion) 10% including fat, phospholipid and glycerol is 1.1 kcal/mL. Of this total, approximately 0.6 kcal/mL is supplied by linoleic acid.
Liposyn II (intravenous fat emulsion) 20% contains 10% safflower oil, 10% soybean oil, 1.2% egg phosphatides and 2.5% glycerin in water for injection.

are saturated and unsaturated fatty acid residues. The major component fatty acids of the 50/50 safflower/soybean oil mixture are approximately 65.8% linoleic, 17.7% oleic, 8.8% palmitic, 3.4% stearic, and 4.2% linolenic acid. These fatty acids have the following chemical and structural formulas:

Egg phosphatides, purified, are primarily a mixture of naturally occurring phospholipids which are isolated from the egg yolk. These phospholipids have the following general structure:
 |
 |
are the same saturated and unsaturated fatty acid residues that abound in neutral fats. R3 is primarily either the choline [HOCH2CH2N(CH3)3OH] ester or ethanolamine (HOCH2CH2NH2) ester of phosphoric acid (H3PO4).
Glycerin, USP is chemically designated C3H803 and is a clear colorless, hygroscopic syrupy liquid. It has the following structural formula:
