( This page is not quite finished, as you can notice. )
Each link is to the safety data supplied by the companies for the brands shown.
Paper products in general do not have an MSDS, but each company will usually on the product page
comment on what the source of the fiber is and how it has been treated during its manufacture.
In the case where a product is made outside of the US and Canada it is probable that no data such as
an MSDS is available, but again on the page describing the product description will be included of
what was used in the product and how relatively green it is.
