Abstract
The present invention relates to the discovery of particular water-based emulsion formulations that comprise an environmentally acceptable integrated floor care maintenance system. In particular, the present invention provides a low zinc, low phosphate, acrylic-based, integrated floor care maintenance system that includes a low zinc acrylic floor finish having a zinc content of less than 100 ppm and a phosphate content measured as percent phosphorus of less than 0.4% by weight and a floor finish stripper having no added zinc, no added phosphate and containing from about 0.01 to 5% by weight of an ammonium perfluoroalkylsulfonate wetting and emulsifying agent, such as CAS number 67906-42-7, CAS number 17202-41-4 or a mixture of these. Additionally, this invention provides for a low zinc acrylate floor sealer having a zinc content of less than 100 ppm and a phosphate content measured as percent phosphorus of less than 0.4% by weight, a buffing composition having a zinc content of less than 100 ppm and no added phosphate, and a floor cleaner having no added zinc or phosphate.
