Use of cationic surfactants as sporicidal agents

摘要

Cationic surfactants derived from the condensation of fatty acids and esterified dibasic amino acids, such as from lauric acid and arginine, in particular the ethyl ester of the lauramide of the arginine monohydrochloride (LAE), may be used for the treatment of objects which are infected with spores. The spores may originate from bacteria or fungi.
