Very good points. Both organic pigments and dyes can be metalized to alter their color. And dyes can be laked on metal compounds to reduce their solubility to make them function as pigments.So you never know when a regulated metal may pop up in your waste.
Thanks for the heads up on ZDHC. Wasn't familiar with them.

I hope I might assist a bit in this conversation. Typical textile dyes do have metal complexes. Some of the less reputable suppliers may contain hazardous
heavy metals (lead, mercury, etc). Most of the newer technologies are moving to copper, zinc, manganese. SDS's are not reliable from that part of the world especially when dealing with a distributor like those mentioned. You would be better served to ask
for a letter of declaration that the dye meets the ZDHC MRSL (www.roadmaptozero.com Zero Discharge of Hazardous Chemicals =E2=80" Manufacturing Restricted Substance List). ZDHC is quickly making progress with textile
chemical manufacturers but there is a ways to go. Many of the large chemical suppliers for textiles recognize that kind of request.
Depending on the quantity (dissolved or in solution) you should check with your wastewater treatment facility to let them understand that a =E2=80=98slug' of these
types of chemicals are being released in your discharge water. For the dry chemicals or pastes, they should be disposed of according to local regulations and you may need to have a chemical analysis done to understand which hazard, if any, apply.
I hope the information is of some assistance.

Second answer: I went on both Dharma's and ProChem's sites and looked at their SDSs. They have chosen this new SDS document to tell you NOTHING about the dyes.
They are using internal product identifiers. There are no C.I. name or any other information.
That really is sad. But at least ProChem says up front they are sensitizers--which is the bid industrial issue with all of the Reactives.
In Section 11 Dharma just tells you there is no data which is true. The Prochem deceptively leaves off the fact that there is no chronic data which artists interpret
to mean they are safe.
Oy. You should see the structures of many of these. People should be very careful with these powders. Costume shops usually have glove boxes or chemistry fume
hoods for mixing the powdered dyes. Art people usually wallow in them instead.
Sheesh. I train people how to look up the hazards and now it is a useless skill since the major suppliers to the arts are not telling them what they are.

Subject: [DCHAS-L] Fiber dye disposal?
I wonder if anyone has looked into the disposal of fiber dyes used in student activities events?
The particular brand I'm interested in is from Dharma Trading Company and their SDS's are remarkably uninformative. The SDSs states
Waste Disposal Methods: Should not be released into the environment. Dispose of in accordance with local regulations. This material, as supplied, is not a hazardous waste according to state and federal regulations (40 CFR 261).
The local sewage authority would like to know if there are metals in the dyes, but the company representative only knows what's on the SDS that came with the powder they bought from their supplier, so I would like to have a source of corroborative information
for the SDS before I respond to the city. Any suggestions for other sources of information would be appreciated.
Thanks for any information on this.
