Abstract
Abstract A selfpolishing cleaning floor wax having, as essential components, a synthetic-resin dispersion (preferably containing a styrene-acrylic copolymer), and an emulsified oxidized polyethylene in an amount of 0.5 to 50% by weight of the dry product. The oxidized polyethylene is of the short-molecule type with a molecular weight of 5,000 to 20,000, an acid titer or number between 20 and 50 and a softening point between 120* and 150*C.
