Abstract
A composition of matter suitable for controlling allergens in fabrics comprising an aqueous film forming solution having a pH from between about 7 and 10 wherein the resulting film: A. has a minimum film forming temperature (MFT) below about 30.degree. C, b. contains polymers having a glass transition temperature (Tg) less than about 20.degree. C, and C. is hydrophobic, substantially non-nutritive, flexible, continuous, and autosoluble. Repetitive application of these coatings to certain fabrics in a household has been found to substantially reduce the activity of pyroglyphid mites and their debris with a corresponding reduction in the allergy potential of these fabrics.
Claims4
A method of controlling pyroglyphid mite activity in fabrics comprising coating the fabric with an aqueous film forming solution having a pH from between about 7 and 10 to produce a film having a MFT below about 30.degree. C, said film containing a major amount of a polymer having a Tg less than about 20.degree. C wherein the film is hydrophobic, substantially non-nutritive, flexible, continuous and autosoluble.
