Abstract

The invention relates to a wax composition comprising linear hydrocarbons, branched hydrocarbons and oxidized hydrocarbons, wherein the composition is characterized by a congealing point from 68° C. to 110° C., an acid number in the range of 3 to 30 mg KOH/g, a saponification number of 20 to 90 mg KOH/g and a needle penetration at 25° C. of below 15 1/10 mm. The invention further relates to an aqueous dispersion comprising the wax composition and a method of manufacture of both the wax composition and the dispersion. The wax composition can be used to fully or partially substitute Carnauba wax or Candelilla wax.
