Hydroxylamine Sulfate safety?
The first MSDS I pulled up claimed
"May decompose explosively in the presence of alkalies." Now does that mean in the developer I'm going to mix??? Potassium Carbonate would be considered an alkalie wouldn't it? It's only going to be a 3% solution but I'm not inclined to go boom. Nick |

I have trouble crediting the possibility of a 3% solution exploding, and if it did, I don't think it would be included in a developer formula. If it worries you, try this: Take up the smallest amount of the hydroxylamine sulfate solution practical in a dropper, and drop a single drop into a small pile (a gram or so) of potassium carbonate powder. You'll likely see a reaction, since the material will probably still decompose, but if it were to explosively decompose, the quantity is such that it shouldn't be hazardous. Do wear goggles, though, just in case; it doesn't take much of a reaction to scatter the carbonate granules around. -- I may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E. J.

The thing that got to me was that the rest of the MSDS on that website seemed very common sense based. Nick |

Hi Nick,
I use the powder all the time. No problem. I just add ingredients in the order called for by the formula. Francis A.
