Abstract
Abstract A method for manufacturing bromine and bromine-iodine agents with detergent and disinfecting activity which comprises reacting a complex dibromineiodine ion [IBr2]-or iodine bromide IBr with non-ionic surfactants, e.g. fatty alcohols extended with ethylene oxide, alkylphenols extended with ethylene oxide etc. When [IBr2]--ion is used in the synthesis, a bromine complex compound corresponding to the general formula R-(OCnH2n)x-OH . . . Br-Br . . . HO-(CnH2nO)x-R, wherein R represents an alkyl, alkylamido, aryl or alkylaryl radical of 6-32 carbon atoms n is an integer from 2 to 4 and x is an integer representing the number of oxyalkylene groups and has a value from 2 to 50, is obtained.
