Abstract
Abstract A wax composition contains a water-dispersible polyethylene wax and an amount (1-25% or more specifically 6-12% by weight on the composition) sufficient to inhibit changes in viscosity normally exhibited by the wax of a primary aliphatic saturated or unsaturated monohydric alcohol containing 4 to 20 carbon atoms, e.g. cetyl, stearyl, or oleyl alcohol or 2,2-dimethyltetradecanol. The wax may have a M.W. of 1000 to 6000, a density of 0.90 to 0.97, a ring-and-ball softening point of 90-112 DEG C., and an acid number of 4 to 25. In Example 7, stearyl alcohol is added to a degraded non-dispersible polyethylene wax prior to oxidation at 150 DEG C. with oxygen.
