Cationic surfactants derived from the condensation of esterified fatty acids and amino dibasic acids, such as lauric acid and arginine, in particular the lauramide ethyl ester of arginine monohydrochloride (LAE), can be used for the treatment of spore-infected objects. The spores can have origin in bacteria or fungi. Claim 1: Use of cationic surfactant derived from the condensation of esterified dibasic fatty acids and amino acids, according to the following formula (1) wherein X- is Br-, Cl- or HSO4-, a counter ion derived from an organic acid or inorganic, or an anion based on a phenolic compound; R1 is a linear alkyl chain of a saturated fatty acid or a C8-14 hydroxy acid linked to the alpha-amino acid group through an amide bond; R2 is a linear or branched C1-18 alkyl chain or an aromatic group; R3 is -NH3, or as in formulas (2), and n can be from 0 to 4, for sporicidal treatment. |
