Abstract
An absorbent floor cleaning and waxing composition is disclosed comprising shreds of a hydrophilic, open-celled, solids-loaded polyurethane foam having an aqueous wax emulsion releasably incorporated therein. The composition is effective to replace soiled coatings of floor wax with fresh floor wax.
Claims14
A process for preparing a floor cleaning and waxing composition comprising:
- (a) forming an aqueous reactant phase comprising about 30-75% by weight of abrasive solid particles, about 0.1-5% of the weight of the solid particles of a silane-coupling agent, about 0.1-10% of a nonionic surfactant, about 0.1-20% of a silicone fluid, about 5-15% wax and about 20-50% water;
- (b) mixing said aqueous reactant phase with a water-foamable prepolymer resin which contains at least 2 free isocyanate groups per resin molecule so that the final mole ratio of water to total free isocyanate groups is within the range of about 5-100:1, thereby shaping said resin into a hydrophilic, open-celled, highly reticulated polyurethane foam bun;
- and
- (c) shredding said foam bun.
