Whatever was cheap, not too toxic, and would make the product a nice colour.

Check the MSDS(Material Data Safety Sheet), they usually have a decent ball-park range of the chemicals you may run into in a certain product.
Although, there is usually contamination, so don't treat the MSDS as a gospel.
