Abstract
Process for the preparation of bis-isothiouronium compounds, characterized in that it comprises condensing thiourea or a substituted thiourea in which at least one of the nitrogen atoms carries a radial alkyl or alkenyl with a 1,1-bis (w-haloalkyl) ) urea and if desired, convert the resulting condensation product into the free base or another salt.
