hi, my question is what chemical combinations can you use to sustain an endothermic reaction at the temperature of 10 degrees for at least an hour and is reusable (you can reset the chemicals). the reaction would be taking place in a product for the public so therefore has to be safe for them to use.

sorry if this is the wrong forum and if is could you point me to the right one.

why don't you just use a heating plate every time the temperature  goes under 10 degrees?
But if you insist of using chemicals to sustain the temperature then at least you should tell us what reaction your doing!!
