Marine organism adhesion preventive agent

Abstract

Abstract PURPOSE:To provide the subject stickproofing agent containing, as active ingredient, specific vanillylamine derivative (s), nontoxic to human and livestock and fishes, etc., causing no environmental pollution, also free from heavy metals and, effective at low concentrations. CONSTITUTION:This stickproofing agent for marine organisms has greatly excellent preventing activity against marine organism sticking and, contains, as active ingredient, at least one kind of vanillylamine derivatives of formula I (R is a 4-11C saturated or unsaturated hydrocarbon) (e.g. vanillyl norylamide of formula II, vanillylmethyl noneylamide of formula III). The aim of this agent can be accomplished by either of the following methods: (1) the compound of the formula I is added in small amount to a seawater cooling system during the sticking and growing of marine organisms such as Mytilus edulis; (2) fishnets are immersed in a solution containing a vanillylamine derivative to fix the compound on the fishnets, and these fishnets are used as culturing nets in marine organism sticking period; and (3) this compound is admixed with a coating film-forming material followed by coating the mixture on objects.
