Emulsion based on a HD polyethylene wax for improving the surface properties of aqueous care products and polishes. AQUACER[R] 506 improves the buffability, increases filling capacity and produces an anti-slip effect. These properties are generated by mixing AQUACER[R] 506 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, protection against heel marks and dirt-repellent action. AQUACER[R] 506 is compatible with all known polymer dispersions and plasticisers and is recommended for polymer-rich self-shine emulsions and polishes.
