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: PA1 A. has a minimum film forming temperature (MFT) below about 30.degree. C, PA1 b. contains polymers having a glass transition temperature (Tg) less than about 20.degree. C, and PA1 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.
