and preferably from 0 1 to 10 by weight in the formulation the present allergen denaturing composition can be any formulation which is exemplified by aqueous liquid spray aerosol paste and powder when the present allergen denaturing composition is liquid for spraying addition of water soluble polymer compound is effective to prevent scattering of powder after dried examples of the water soluble polymer compound include polyvinyl alcohol polyacrylic acid polyacrylic acid salts polyethylene glycol and polyvinylpyrrolidone the content of the water soluble polymer compound is generally from 0 01 to 20 by weight and preferably from 0 1 to 10 by weight in the formulation the present allergen denaturing composition can be applied with the other allergen denaturing agents and for the purpose of removing house dust mite allergens it is effective to apply the present allergen denaturing composition with acaricides these acaricides are not restricted if they have lethal activity and or repellant activity against house dust mites examples of the acaricides include benzyl alcohol benzyl benzoate phenyl salicylate cinnamaldehyde hyssop oil carrot seed oil pyrethroid compounds such as natural pyrethrins phenothrin and permethrin organophosphate compounds such as fenitrothion malathion fenthion and diazinon dicofol chlorobenzilate hexythiazox tebufenpyrad and pyridaben the present allergen denaturing composition can also contain a surfactant chelating agent anticorrosive agent antibacterial agent binder thickener perfume anti scale agents antifoaming agents antistatic agents softener and so on further.
