Procedure

25 l of commercial pure castor oil are saponified in a known manner by adding 7.8 l of 38% strength sodium hydroxide solution and 40 l of water in portions. 12.5 kg of zinc sulphate heptahydrate DAB6, dissolved in water to give a volume of 25 l, are added to the clear sodium ricinoleate solution at about 80° C., and the mixture is thoroughly stirred and thereafter allowed to settle. The zinc soap is separated from the mother liquor and poured hot into moulds, where it solidifies.
