Looking for a non-toxic, heavy-metal free acid dye that conforms to the Organic Trade Association's standards for Organic Fiber Processing?
Greener Shades(TM) is a non-hazardous, non-chrome, low impact, heavy metal-free acid dye for use on silk, wool, nylon, or any animal fiber. Formulated without the use of hazardous metals, these dyes provides superior light and wash fastness without relying on metal compounds to achieve bright and beautiful colors.
This listing is for individual Greener Shades dyes - select from Ruby Red, Flame Red, River Blue, Coral Reef Aqua, Sunset Orange, Sunshine Yellow, Amazon Green and Midnight Black - in either 1/2 oz container. 1/2 oz will dye approximately 3 pounds of fiber/yarn/fabric. You will need to use an acid (usually acetic or citric) plus heat (180 degrees Farenheit) to fix the color.
**As a dye-sensitive individual with a nickel allergy, I can confirm that these dyes are great for individuals with dye sensitivities or heavy metal allergies.
