摘要

Aqueous wax dispersions (G) are characterized by containing (A) a wax mixture of (A1) at least a non-oxidized paraffin wax with 20 dmm needle penetration or less (according to ASTM-D 1321) and a melting range above 65 DEG C; (A2) at least an oxidized hydrocarbon wax with 4 dmm needle penetration or less (according to ASTM-D 1321), and possibly (A3) at least a non-oxidized paraffin wax with 55 dmm needle penetration or less (according to ASTM-1321) and a melting range lower or equal to 65 DEG C; and/or (A4) at least a cationically modified oxidized hydrocarbon wax; (B) a cationic dispersent system, possibly (C) at least a softening and/or antistatic auxiliary and/or (D) a preservative agent and/or an anti-foaming agent and/or (E) at least an amphoteric surface-active agent. These wax dispersions are remarquably suitable as brightening and are used in particular for brightening yarns.
