Protection of formulations, especially aqueous solutions, against microbial growth
requires use of either antibacterial or antifungal preservatives. Generally, such
agents are active against either bacteria or fungi but a few are active against both.
The antimicrobials include but not limited to chlorobutanol, benzyl alcohol, sodium
benzoate, sorbic acid, and phenol. The antioxidizing agents include butylated hydroxytoluene,
hydroxyanisole, propyl gallate, and sulfites. The necessary addition of preservatives
for both safety and economy sometimes has been associated with significant adverse
effects in certain patient populations.;
