Ethyl oleate is one of the fatty acid ethyl esters (FAEE) that is formed in the body after ingestion of ethanol. There is a growing body of research literature that implicates FAEEs such as ethyl oleate as the toxic mediators of ethanol in the body (pancreas, liver, heart, and brain).    Among the speculations is that ethyl oleate may be the toxic mediator of alcohol in fetal alcohol syndrome .  The oral ingestion of ethyl oleate has been carefully studied and due to rapid degradation in the digestive tract it appears safe for oral ingestion.  Ethyl oleate is not currently approved by the . Food and Drug Administration for any injectable use. However, it is used by compounding pharmacies as a vehicle for intramuscular drug delivery, in some cases to prepare the daily doses of progesterone in support of pregnancy. Studies which document the safe use of ethyl oleate in pregnancy for both the mother and the fetus have never been performed.
Cellulose acetate (CA) membranes have a very low binding affinity for most macromolecules and are especially recommended for applications requiring low protein binding, such as filtering culture media containing sera. However, both cellulose acetate and cellulose nitrate membranes are naturally hydrophobic and have small amounts (less than 1%) of non-toxic wetting agents added during manufacture to ensure proper wetting of the membrane. If desired, these agents can be easily removed prior to use by filtering a small amount of warm purified water through the membrane or filter unit. Surfactant-free cellulose acetate membranes with very low levels of extractables are available on some Corning® syringe filters.
EO = Ethyl Oleate. EO is a solvent, which dissolves the steroid powder but its use is to thin the solution’s ’s a thin and expensive oil, created from ethanol, and used as a rubber softener, solvent, and typically used by us as a base for steroid solutions. It provides smooth and painless injections, and will suspend compounds at much higher concentrations than just oil. (It will make 100mg/ml Prop completely painless…) And because it’s a solvent, it allows you to use less Benzyl Benzoate in your blends, however BA is still used to maintain sterility.
