Green Acrylics?
Acrylic paints often contain small percentages of formaldehyde or
ammonia as preservatives. These can cause allergic reactions in some
individuals, especially if they are using large amounts of polymer
medium or gel. Such artists may benefit from the use of gloves and a
ventilation system in the studio. However, another issue should be
considered when choosing acrylics for use in art.
For some time, the EPA has been concerned with the number of toxins
produced in the overall manufacture of acrylic polymers. Roughly 36
billion pounds of toxic solvents are used each year in the production of
acrylics. Much of this is used in the manufacture of textiles, but
toxic solvents are also used in the production of paints. To address the
problem, the EPA has funded a “green initiative” in hopes of finding
less toxic ways of making acrylics. For a summary of the issue, visit: http://www.jeccomposites.com/composites-news/130/ For an intro to acrylic polymers, visit: http://www.polymerchemistryhypertext.com/381.htm#acrylic
Keep in mind the pigment issue as well. Cadmium is carcinogenic. It doesn’t matter if it is in acrylic paint or oil paint.
