Abstract (en)

Match head formulations suitable for the production of safety matches and matches that may be struck anywhere are described which include metal chelate complexes of iron, copper, chromium or vanadium and citric acid, lactic acid, tartaric acid and EDTA. The metal chelate complexes may be combined with conventional match head compositions in which chromium compounds, sesqui-based phosphorus compounds, sulphur compounds and oxides of zinc present or preferably combined with environmentally friendly compositions using either amorphous phosphorus or, optionally, in the case of match head formulations suitable for the production of safety matches, an iron phosphide known as ferrophosphorus. These formulations are environmentally friendly both in manufacture and use. Environmentally friendly match head formulations which may be brightly coloured are also described.
