    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.

  • Patent number: 4200437
    Abstract: A method for the manufacture of matches which comprises applying to a match splint, before the formation thereon of the match head, a surface coating of an aqueous dispersion comprising (i) a low melting point solid fuel e.g. paraffin wax, (ii) a finely divided particulate or fibrous filler and (iii) either a water-immiscible volatile solvent for the fuel or a water-soluble or water-dispersible adhesive, or a mixture of the two; and thereafter drying the coated splint to deposit thereon adjacent the end thereof, on which the head is to be formed, a surface coating comprising a mixture of said fuel and said filler, and, if present, said adhesive.
