Match head formulations

Abstract

Match head formulations suitable for the production of safety matches and matches that may be struck anywhere are described in which chromium compounds, sesqui-based phosphorus compounds, sulphur compounds and oxides of zinc are absent. In their place is described the use of either amorphous phosphorus or, in the case of match head formulations suitable for the production of safety matches, an iron phosphade known as ferrophosphorus. These formulations are environmentally friendly both in manufacture and use. Environmentally friendly match head formulations which may be brightly colored are also described.
