The invention provides a zinc higher fatty acid salt block formed product which is useful for a lubricant, a cleaning auxilliary and the like without a risk of trouble of cracking, is reduced in the variation of hardness and in the amount ground with a brush or the like, and effectively used as a lubricant and a cleaning auxilliary for the office equipment such as an electrostatic copier and other precision apparatuses. The zinc higher fatty acid salt block formed product is produced by the cooling and solidification of a heated and fused composition containing (A) 100 parts mass of a high purity zinc higher fatty acid salt with a purity of 99.8% or over and (B) 0.1-1.0 part mass in terms of a metal of a lower fatty acid salt, a higher fatty acid salt and an inorganic carbonate containingan alkali metal of the group I in the periodic table or an alkaline earth metal of the group II in the periodic table.
