The Canadian Conservation Institute used to have a Commercial Product Analytical Report that listed different commercial products that CCI had tested.  I think it was last done in 1992, but you may want to contact CCI to see if they have any information on acrylic gel mediums.

Is there a reference publication available with information on the archival
quality of various consumer products?  I know Decor magazine would do spot
stories on particular products, but is there a central authoritative text
on this?
