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.
