Hello,
Newbie question here, but I can't easily find an answer on the internet. I'm looking to transfer prefilled syringes that are sterile water and TZ 5m/0.5ml into vials so that RS can take 2.5mg doses twice a week (instead of 5mg dose once a week). I'm trying to figure out what the minimum percentage of benzyl alcohol is required to make a solution bacteriostatic. I'd like to add 1ml BAC water to 1ml TZ solution (two prefilled syringes), which would put the benzyl alcohol percentage around 4.5%, but I don't know if that's enough to make the solution bacteriostatic. If the concentration needs to stay at 0.9-1.1% to remain bacteriostatic, then obviously I can't make this work as it will always dilute below that if I add the TZ solution, but maybe there's a lower percentage that would still work?
Thought someone here might know. Thanks for the help!
