Abstract: 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.

Abstract: A solid composition comprising a cationic surfactant, such as the ethyl ester of the lauramide of the arginine mono-hydrochloride (LAE) and a polyene fungicide such as natamycin is provided. The solid composition is the basis for providing solutions of natamycin of increased concentration. The solid composition may be used for providing a dispersion of natamycin in a suitable liquid, such as tap water or an organic solvent. The dispersion may be further diluted with water. This leads to a solution of natamycin in water. The combination of the cationic surfactant and the polyene fungicide displays a biological effect which is stronger than the effect of each of the two components alone.

Abstract: Use of cationic surfactants, derived from the condensation of fatty acids and esterified dibasic amino acids, of the formula (1): occasionally leads to a bitter taste, when the compound is present in a large concentration. The bitter taste can be masked by combination with a second component selected from the list consisting of sucralose, neohespiridin (NHDC), ?-cyclodextrin, mono ammonium glycyrrhizinate (MAG), banana, mentholyptus, sodium dodecyl sulphate (SDS), anetol, menthol, thaumatin, adenosine monophosphate (AMP), aloten, arginine, sodium acetate, arilic acids (ferulic acid, caffeic acid), sclareolide, maltol, anane, phosphatidic acid, eucalyptol, lactisole, lysozyme, lactoglobulin, timol, borneol, acetol, phosphothreonine, phosphotyrosine, phosphoserine, Masking flavour 501521T, Masking flavour 501522, saccharine, aspartame, MK22 N&A FL for masking #25682, MM24 Prosweet N&A FL Enhancer, neodiosmin, xylitol, stevia and Natural and Functional Flavour (NAF®).
