Abstract

Decominol exhibits bactericidal activity in a concentration of 0.05% (NF T 72-151). This concentration is increased five-fold in the presence of an albumin-yeast extract mixture, and 2.5-fold in the presence of hard water (60 degrees French). At pH 5.0, 0.5% concentration is not bactericidal (NF T 72-171) Fungicidal activity (T 72-201) is weak at 20 degrees and 50 degrees C and the sporicidal tests (T 72-231) establish the lack of sporicidal activity at 10%. Decyloxy-3 hydroxy-2 in 0.2 amino-1 propane hydrochloride to 1.5% concentrations used in a meat-canning factory ensures satisfactory disinfection of correctly cleansed surfaces. It also proves useful for sterilization of circuits where it can be used as an adjunct to the lethal action of heat.
