Abstract (en)

[origin: EP1604963A2] The pyrotechnic composition, which includes at least one oxidant and at least one reducing material, incorporates between 1 and 40 per cent, and preferably 1 - 10 per cent of myristic acid, which occurs naturally in animal fats and plant vegetable oils such as copra and palm oil. The reducing material is an organic acid selected from the following group: glutamic acid, acetylsalicylic acid, fumaric acis, stearic acid, ascorbic acid or mixtures of these. The oxidant material is selected from the group comprising potassium perchlorate, ammonium perchlorate, potassium nitrate, ammonium nitrate or mixtures of these, and a typical version of the composition contains 30 - 70 per cent of oxidant material, 20 - 40 per cent of a reducing mixture containing myristic acis and at least one organic acid, 0 - 10 per cent of a bonding agent, and 0 - 10 per cent of a catalyst such as ferric oxide (Fe203).
