Abstract: A metal soap pellet is made by compressing or heating and cooling a mixture of (a) a metal soap (such as a metal stearate) and (b) a plurality of components (such as (i) a metal oxide, hydroxide, or carbonate and (ii) a monocarboxylic acid) which are capable of reacting together under heat and/or pressure to form a metal soap. The metal soap pellets of the invention are non-dusting and durable. They are excellent plastics additives and are particularly useful for applications where the presence of a separate binder is unacceptable.
