- BNon-irritable
- CCompatibility with physiological fluids
- DSterility

5Preservatives prevent [blank_start]microbial[blank_end] contamination of aqueous pharmaceutical products, but are not usually required for a [blank_start]single-use[blank_end] product. Ideal preservatives are non-toxic, non-sensitising, odourless, tasteless, effective in [blank_start]low[blank_end] concentrations, effective against [blank_start]variety[blank_end] of microorganisms, and [blank_start]compatible[blank_end] with other components.
Often [blank_start]mixtures[blank_end] of preservatives are used to [blank_start]increase spectrum[blank_end] of antimicrobial activity. The [blank_start]synergistic[blank_end] effect also means [blank_start]lower[blank_end] concentrations can be used.- Amicrobial
- Bsingle-use
- Clow
- Dvariety
- Ecompatible
- Fmixtures
