Procedure

A suspension consisting of 8.5 g zinc oxide (95% active, precipitated, particle size 50μ, density 5.4 g/cm3) and 67.8 g behenic acid (AN 165, titer 75° C., particle size 0.2-0.3 mm.) which has been obtained as a granulate from an aqueous dispersion as described in Example 1 and is contained in 1.3 liters of water, is stirred first for 30 minutes at 60° C. and then heated to 100° C. After agitation for one hour at this temperature the granulate still contains 4.4% free fatty acid. After 2 hours this is reduced to 2.7% and after 3 hours only 2.0% free fatty acid remains.
