Scotch Guard is the product most familiar because for decades hundreds of thousands of dollars have been spent making the product a household name. Scotchgard is to Water repellents as Kleenex is to “Tissue”.
Scotchguard was recently discovered to contain PFOS (perfluorooctane sulfonate), an ozone depleting chemical, which is known to damage the liver and produce birth defects in lab animals. It was discovered that PFOS were in blood samples from all over the world, in children, in Alaskan polar bears, and in bald eagles from the Great Lakes. Scotchgard has since changed its formula which you may now compare to the below mentioned Silicone /water based products that may discolor fabrics and actually attract soil to the fabric surface.
Stain Free contains no PFOS and unlike the Scotch Guard products, protect against oil based stains as well as water based.
The other products on the market fall into two basic categories:
Water Based Chemicals:
