Message: First of all i would like to thank you for your great informative site, it was a lot of help to me and made me learn many good things.

Second i want to ask you a technical question since you are an expert in the Procoin MX reactive dyes, i tried some dyes from Dharma trading company and they were nice but they don't ship internationally (we are non US resident), so i want to know if ProChem company offers the same color shades as Dharma, as i already made my T-shirt samples using Dharma's colors and now i have orders on them, and that makes me afraid to change my source of Dyes.

Some of the dyes are, chemically, exactly identical, whether you buy them from Dharma Trading Company, ProChem, or any of the other international sources listed on my Sources for Supplies page. The only difference is that, perhaps, one company might have slightly fresher or better-dissolving dye than another, or use a different powder diluant, so that the same strength of dye by weight occupies a larger or smaller volume. ProChem is noted for their high dye quality.

Other dye colors are mixed in-house by the retailer, so it is impossible to find exact equivalents for these from one dye supplier to another. The exact dye content of each of these mixtures is a trade secret.

You can tell which is which from a table available on my web site, "Which Procion MX colors are pure, and which mixtures?". The pure dyes are the same dye chemical whether you get them from one source or another. There are a few mixtures with MMX codes which are purchased pre-mixed by the suppliers, and which may be the same color from one source to another.

You can also ask when you order, by phone or e-mail, whether a given dye is a pure, unmixed color, or whether it is a proprietary mixture made by the retailer. You might even be able to get their advice on the most likely replacement for the proprietary mixture of one of their competitors.
