Combinations of polyene fungicide with cationic surfactants

Composition consisting of natamycin an a cationic surfactant (LAE)


A solid composition comprising a cationic surfactant, such as the ethyl ester of the lauramide of the arginine monohydrochloride (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.
