Abstract: An antifungal composition comprising 3-iodo-2-propynyl butylcarbamate, 4,5-dichloro-2-octyl-isothiazolin-3-one and methyl 2-benzimidazolylcarbamate is useful as industrial antifungal composition, particularly for wood protection.

Abstract: Application of an alkaline earth metal salt selected from calcium and strontium salts can steadily denature the allergens those exist in the environment without any coloring trouble on the treated material.

Abstract: A polymer emulsion with good film forming property, which is mixed a synthetic polymer emulsion containing the polymer having the particle size of 0.15 &mgr;m or longer in diameter and a synthetic polymer emulsion containing the polymer having particle size of 0.10 &mgr;m or shorter in diameter, wherein the glass transition temperature of the latter polymer is at least 20 degree lower than that of the former emulsion and the particle size ratio between the former polymer and the latter polymer is 2 or more. The polymer emulsion is used for making moisture-proof coated paper and/or recyclable-coated paper.

Abstract: The present invention provides use of a composition containing 2-n-octyl-4-isothiazolin-3-one and N-n-butyl-1,2-benzisothiazolin-3-one for providing antifungal efficacy to a wood preservative containing copper oxide or a copper salt and a fungicidal azole. It also provides a wood preservative which comprises 2-n-octyl-4-isothiazolin-3-one, N-n-butyl-1,2-benzisothiazolin-3-one, copper oxide or a copper salt, and a fungicidal azole as active ingredients.

Abstract: A method for denaturing allergens with an effective amount of a rare earth metal salt.
