摘要： PURPOSE:To provide an antifouling agent having high safety and excellent antifouling effect and effective for preventing the adhesion and proliferation of harmful aquatic life such as shell and alga to the bottom of a ship, a facility in seawater, a construction in water, an inlet channel for cooling water, etc. CONSTITUTION:The objective antifouling agent contains a straight-chain saturated monocarboxylic acid expressed by formula CH3(CH2)n COOH ((n) is integer of 2-16) as an active component. Since the active component of the antifouling agent is a compound originated from natural source and frequently found as a food component, it has high safety to human body as well as environment. It does not kill the periphyton but exclusively inhibits the adhesive function of the life and has high safety to fish and shellfish. The active component may be used singly or in combination with other antifouling agent. For example, the antifouling agent is a chemically synthesized compound, an extract of natural oil and fat or algae containing the above compound, their hydrolyzate or pure substance separated from the extract. The amount of the active component is preferably 2-30wt.% for paint based on the film-forming agent, 5-20wt.% for solution based on the solution and 2-30wt.% for emulsion, respectively.

摘要： PURPOSE:To obtain an antifouling agent effective for preventing the adhesion of aquatic organisms to ship bottom, fishing net, buoy, marine construction, etc., by using a 2-hydroxymonocarboxylic acid having high safety, antifouling effect on and repelling activity against noxious aquatic adhesive organisms as an active component. CONSTITUTION:The objective antifouling agent effective for preventing the adhesion and proliferation of harmful aquatic organisms can be produced by using a 2-hydroxymonocarboxylic acid originated from natural source, exhibiting high decomposability in natural environment and having high safety to human body and environment as an active component. The antifouling agent does not kill the adhesive organisms but inhibits only the adhesive function of the organism. It has excellent repelling effect on harmful aquatic adhesive organisms and high safety to fish and shellfish. Since 2-hydroxymonocarboxylic acid used as the active component is present e.g. as a constituent component of natural sphingolipid, it can easily be obtained by extraction, etc.

摘要： PURPOSE:To provide a control agent containing a specific indole compound having high safety and an excellent control effect as an active ingredient and preventing injurious aquatic organisms from adhering and multiplying to and on ship bottoms, fishing nets, buoys, cooling water intake channels, etc. CONSTITUTION:The aquatic pest adhesion control agent contains an indole compound of the formula (Y is H, lower alkyl, phenyl; X -X are H, halogen, alkyl, alkoxy, nitro, cyano, phenyl, aralkyl, aralkyloxy, nitrovinyl, pyridylalkyl, etc.,) as an active ingredient. The compound of the formula includes 2,3- dimethylindole, 3-indrylacetonitrile, and ethyl 5-chloro-2-indole carboxylate. The compound of the formula is used as an active ingredient e.g. for coatings, solutions, emulsions. The aquatic pest adhesion-preventing agent has an excellent aquatic adhesive pest-repellent effect, holds a larger effect than those of heavy metal compounds, and is safe for human bodies and environments.
