If this is the same stuff I came across in my kid's elementary school
classroom a few years ago, it is polyacrylamide and the kids were
playing with it with bare hands. They say it is a "Non-toxic polymer,
safe for home use", but that contradicts what we protein biochemists
have always been taught. True, the polymer is probably safe, but the
polymer always contains some monomer and the monomer is a known
neurotoxin that passes through the skin and accumulates in the body.
What are we to believe? Have the appropriate MSDS sheets been
generated? Or were MSDS sheets generated with the intended use being as
a soil amendment and not likely to be touched by kids? Am I over reacting?
By the way CRSTALWTR, please don't use Plant-ed to distribute unpaid
advertisements in the future. Thanks.
