Abstract

Aqueous dispersions of ethylene copolymer waxes, which dispersions are free-flowing at room temperature, contain a mixture of an ethylene copolymer wax having a high acid number and an ehtylene copolymer wax having a low acid number. The novel mixtures are particularly suitable as surface preservatives, as components in floor care agents or as sizes in textile finishing.
