Message: | Benzyl alcohol is used as a bacteriostatic preservative at low concentration in intravenous medications, cosmetics and topical drugs.BA is the antiseptic which keeps the steroid solution sterile.Benzyl Alcohol (BA):A fairly potent solvent, whose main function for our purposes is keeping a solution bacteriostatic. It's presence as low as 0.9% is enough to prevent practically all microbial growth in solution.
Benzyl Alcohol is often the primary solvent and sometime the only solvent in a steroid given formula. Its primary function is as a sterilizing agent. However, due to its solvency power it is often used to keep hormones in solution with oil or other vehicles. It is also one of the thinnest (that is best for viscosity reduction).
Its use in Steroids is to preserve the suspension for months, even years, without any reduction in sterility. Alcohol is an antibacterial disinfectant and is used as such in many industries. As aforementioned Benzyl Alcohol ensures the Steroid maintains its sterility when used in the right concentration.
