Basically it's a bit like passfires only you can enter 10 chemicals to search for instead of just one. It only has about 150 compositions right now but shall have more soon. Also I am working on a page on there that is working roughly that allows you to enter every chemical you have and it will only display formulas that contain nothing but chemicals you have.
You have to signup to use it and this is simply so I can see how many people are using it. If you are willing to take a little time to add some formulas then please let me know so I can give you the password to the add formula form.
So I hope you all find it useful
