A systematic study comprising 28 synthetic ionic and nonionic surfactants was carried out in order to examine their effect on the activity of elastase and cathepsin G from human leukocytes against 4-nitroanilide substrates. The whole spectrum, ranging from a complete loss to a pronounced rise in enzymatic activity, was observed at a 0.1% (w/v) surfactant concentration. Most significantly, benzalkonium chloride led to a five-fold increase in elastase activity.
