Emulsion based on a HD polyethylene wax for improving the surface properties of aqueous care products and polishes. AQUACER[R] 519 improves the buffability, increases filling capacity and produces an anti-slip effect. These properties are generated by mixing AQUACER[R] 519 with polymers in a ratio of 3:1 (solid wax to solid polymer). A mixing ratio of 1:6 increases the water- and alcohol-resistance, the protection against heel marks and the dirt-repellent action. AQUACER[R] 519 is compatible with all known polymer dispersions and plasticisers and is recommended for self-shine emulsions and polishes.
