Health and Safety:
Store in a cool, dry space out of direct sunlight and out of reach of children. Use air-tight containers for storing all powders and liquids. Always replace lids tightly after using dye powders and chemicals.
Keep out of reach of children. Wear gloves, a dust mask, and protective clothing while handling. Do not swallow. Do not inhale. Harmful to aquatic life unless the dye bath is fully exhausted and PH balanced. This product is for dyeing craft and textile fibers only. Dye color may vary from batch to batch. When used correctly acid dye is non-hazardous to humans and the environment.
Proper Disposal Guidelines:
Dye solutions do not store well for long periods. It is important to prepare only as much dye as you will use.
When you are completely finished with an acid dye bath, you should neutralize the bath. Add baking soda 1 tablespoon at a time and use pH test papers to verify that the exhausted bathwater is neutralized. Then pour the exhausted dyebath down the drain, flushing with plenty of water.
Tip: If you have a bath with a lot of leftover dye, another option is to store it in plastic jugs. Most communities have clean-up days where they will collect household chemicals. Be sure you label the contents of the containers.
