Recently I was asked about adhesives used on stickers (the type children play with) and whether they might contain wheat. Unfortunately there is a lot of misinformation floating around stating that adhesives on stickers, stamps, and envelopes often contain wheat starch. There are even claims out there stating that self-adhesive varieties of these products are harmful because they contain gluten and gluten is absorbed into the skin.
Bottom line: You really should not be concerned about gluten in adhesives used on stamps, envelopes, and stickers. Here’s why…
First of all, there is no reason to believe that gluten is absorbed through the skin. As I wrote in Gluten in Personal Care Products: A Need to Worry? posted on July 14, 2009,
“There is no scientific evidence that the use of gluten-containing products that are not ingested is harmful to persons with celiac disease. This includes individuals with dermatitis herpetiformis.
According to Dr. Alessio Fasano, Medical Director of the Center for Celiac Research, University of Maryland, "If you have celiac disease, then the application of gluten containing products to the skin should not be a problem, unless you have skin lesions that allow gluten to be absorbed systemically in great quantities.
The reason why this should not be a problem is that, based on what we know right now, it is the oral ingestion of gluten that activates the immunological cascades leading to the autoimmune process typical of celiac disease.”
There aren’t too many individuals on the planet who know more about celiac disease than Dr. Fasano, so please, do not let anyone, including medical professionals convince you that gluten protein can be absorbed through the skin and cause a celiac disease reaction. It simply isn’t true.”
So, if you are using self-adhesive stickers, self-adhesive stamps, or self-adhesive envelopes there really is no need to worry about whether they contain wheat starch. You don’t have to lick them and if there is any wheat starch in the product, it will not be absorbed through the skin. If you are worried anyway, simply wash your hands after handling these products. When it comes to stickers, stamps, and envelopes that require moistening, there also is no need to worry. Don’t lick them! Use water instead of saliva to moisten them.
BUT, if you still want to know whether these products contain wheat starch, read on…
