In a private note to me, Duane Goldman kindly pointed out that there are care and handling instructions in the report from Environment Canada that I linked to in my blog post. I would also suggest looking for MSDS for the chemical, and will update the blog post with a link or two. On the other hand, D5 is widely used in personal care products to provide the "slippery" feel in shampoos and soaps. We are putting a lot of this on our bodies and hair on a regular basis, so, if concern is warranted, I think it should be directed towards the personal care industry (and there are some grass roots issues in that area, although the weight of the data appeared not too strong in the Environment Canada report). Hence my comment about getting it while the getting is good. Who knows what will happen next year. D5 is also used for "green" dry cleaning. Cheers, Richard On 2012-10-09 10:42 AM, Richard L.
