Benzalkonium solutions obtained from different manufacturers were shown to have different activities. This difference in activity was related to the composition of the benzalkonium chloride. The potential seriousness of this situation is emphasized, and a recommendation is made that the official monographs on benzalkonium chloride be amended appropriately, noting the apparently superior antibacterial activity of the tetradecyl (C14) homolog.
已证明不同厂家生产的苯扎氯铵溶液具有不同的活性。这种活性差异与苯扎氯铵的成分有关。强调了这种情况潜在的严重性，并建议适当修订苯扎氯铵的官方专论，同时指出十四烷基（C14）同系物明显具有更强的抗菌活性。
