I read Scotchgard as “Scotland” at first and was very confused
Post Its were an accident too – 3M has been lucky.
And scientist have found Scotchgard in polar bear blood. That shit doesn’t go away. It doesn’t biodegrade.
“Polar Bears Facing Double Whammy”
Some contaminants appear to be from newer sources. Ross says that traces of fire retardant chemicals known as PBDEs have been found in the bears. These compounds are still applied to furniture and construction material in the United States.
**Another group of compounds identified was, until recently, one of the key elements of Scotchguard. The parent company, 3M, removed the chemicals from their product in May of 2000, due to concerns about its effect on the environment.**

One of the most insidious chemicals ever made.

Seems like most of the great discoveries in life are made my accident
Sucks that it was discovered while working at 3M or they would have owned the patent, same with post it’s.
