Propylene Glycol: one of the co-stars in Polyester Resin

Back in 2010, when I was discovering my allergy to synthetic fabrics and surfaces, I decided to do a little research, thinking, "Could there be a link between my chemical allergies and my bad reaction to 100% polyester sheets?"

Turns out, that may very well be true. I started to research how polyester is made and came across polyester resin. Lo and behold, the process involves propylene glycol, which I'm very allergic to!

Polyester resin is used in a number of items from bathtubs to counter tops and more. This realization helped me figure out why I had a long-standing patch of bad eczema on my right wrist: it was resting on laminate counter top all day!  I placed a piece of paper under my wrist and the eczema never came back. Now, I cover my desk with glass at work and at home, I use bandannas underneath my slide-out keyboard and mouse. There are different types of laminate, but the cheap stuff is made with polyester resin, unfortunately.

Polyester resin is created by propylene glycol reacting with a dibasic or polybasic acid. And it's used in a LOT of stuff. Some other place you can find polyester resin? See below:

  • in construction as an adhesive
  • fiberglass
  • luggage: as adhesive holding on the metal hardware
  • coats
  • outdoor furniture
  • packaging: bonding the plastic and cardboard together in blister packaging
  • underground utility boxes
  • sheet moulding compound
  • automotive panels
  • carbon fiber
  • kevlar

Do you know of any other uses for polyester resin?

Have you had this same problem?
