Abstract: An allergen reducing composition capable of reducing allergens such as mites and cedar pollen and causes less coloring of an allergen reduction target; a spray agent using the allergen reducing composition; a surface treatment agent using the allergen reducing composition; an allergen reducing method; an allergen reducing textile structure; and an allergen reducing architectural interior material. The allergen reducing composition contains: (A) one or more compounds selected from zinc salts and copper salts; and (B) one or more compounds selected from rare earth salts. The spray agent or the surface treatment agent contains the allergen reducing composition and water or a water-soluble solvent. An allergen reducing method involves using the above-mentioned allergen reducing composition in an environment where allergens are present. The textile structure is a textile structure processed by the allergen reducing composition.

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 microencapsulated insecticidal composition comprising a pyrethrin encapsulated in a wall formed of a synthetic polymer and having an average particle diameter of 5 to 100 &mgr;m and wall thickness of 0.03 to 1 &mgr;m is effective for controlling insects.

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

Abstract: Application of a rare earth metal salt can steadily denature the allergens those exist in the environment without any coloring trouble on the treated material.

Abstract: An antifungal composition made up of at least one compound represented by the formula (I): ##STR1## wherein X represents a group of the formula --NHCOOR in which R is --CH.sub.3 or --C.sub.2 H.sub.5, or 4-thiazolyl group and at least one compound represented by the formula (II): ##STR2## wherein Y represents hydrogen or halogen, Z represents halogen and R represents alkyl group of 1 to 8 carbon atoms. The composition preferably comprises 10 to 90% by weight of the compound(s) of formula (I).

Abstract: Applicants' invention relates to a method for dissolving a solute material in a container by contacting the solute with a solvent in another container. Applicants' method relies upon the difference in the specific gravities of the solvent and the solute to create a convection current between their respective containers. The material, either the solute or the solvent, having the larger specific gravity is placed above the material having the smaller specific gravity, and the two materials are brought into contact. The solute dissolves in the solvent, and the resulting solution, which has a lower or higher specific gravity than the solvent, causes a convection current which draws the heavier material down and the lighter material up. As the convection current proceeds, the undissolved solute continues to come into contact with fresh solvent accelerating the dissolution process.
