The article states that smokeless gunpowder produces "negligible smoke when fired". I'll take that to mean that some smoke is nevertheless produced. Does anyone know if inhaling this smoke is known to have any adverse health effects? Appleseed 17:04, 28 September 2005 (UTC)[reply]

Smokeless does not mean free of fumes. Over exposure to fumes may cause adverse health effects.Pyrotec 17:42, 6 May 2006 (UTC)[reply]

Health risks depend on the kind of powder; especially on the non-burned parts of it. K2CO3, K2SO4, CO2 and N2 as residues from traditional powder are not exactly a problem; K2CO3 and K2SO4 are merely irritants. But Sulfur and KNO3 are.

BTW: I had the impression that the first "smokeless powders" were simply powders which contained no sulfur (sulfur only lowers the ignition temperature, and isn't strictly necessary; but this was only found out late in the 19th century). --Seegras (talk) 16:47, 8 December 2009 (UTC)[reply]

Maxim's seminal patent is mentioned and linked at the end of the article but it is not included in the history area also without the leading zero to make a 7 digit patent number 0430212 rather than 430212 the link fails, this is the proper link to the patent in question but I do not know enough about edeting here to change it Windshadow 03:03, 4 June 2006 (UTC)[reply]

I deleted the sentence in history that said something about the Chinese smokeless powder. The reason I did this was because it linked to both a Chinese language Wikipedia article and a Chinese language external link. I don't think the average English language Wikipedia reader could read the two. Johnnieblue 01:33, 16 September 2007 (UTC)[reply]

correction to "instability and stabilization" section

In the section titled "instability and stabization", the it lists 2-nitrodiphenylamine, 4-nitrodiphenylamine and N-nitrosophenylamine as additives for stability. They are not the additives, however they are a product formed when Diphenylamine is present during the decomposition of nitrocellulose. It absorbs the nitrogen oxides that are produced in decomposition of nitrocellulose.

That is not completely true; yes they are decomposition products of diphenylamine, but diphenylamine is not used in some propellants, 2-npda (for short) is used in its place.Pyrotec (talk) 22:15, 31 January 2008 (UTC)[reply]
