Is there any info out there, concerning Rit fabric dyes. (?) primarily, what chemicals are used to make the black shade ?
Here is their MSDS sheet link. It tells you everything about the product, but not the individual ingredients per color. All you are going to find is "organic and inorganic compounds" http://www.wardrobesupplies.com/assets/products/4688/safety_sheets/Rit%20Liquid%20Dye%20-%20Phoenix%20Brands.pdf?1324325148 You could contact Rit directly and ask them http://www.ritdye.com/content/contact-us-0
