Standard single-use ampoules lack preservatives. This specific diluent includes 0.9% benzyl alcohol (a compound that halts bacterial growth once you pierce the seal).

This feature makes theBAC water This is particularly useful when a reconstituted solution needs to be administered in multiple doses over time, as it allows for safer storage of the product—generally for up to 14–28 days if properly refrigerated.

Users trust this formula. It brings obvious practical benefits and a wider safety margin than plain sterile liquids. The diluent is now the normal choice for clean injections.
