Are horse parts really used to make glue or is that just an icky rumor?

Matt Hickman helps a teacher sort out a sticky situation involving glitter and a roomful of 8-year-olds.

Q: I’m a newbie elementary school teacher with a rather odd question. Last week, I attempted to lead my class in a Valentine's Day crafting free-for-all. Construction paper, glitter and all the fixin’s were distributed. The final items passed around were little, innocuous bottles of Elmer’s Glue.
 
Mari, one of my more precocious students (I also suspect her parents are members of the local 4H club), took one look at her bottle and turned as white as its contents. She then shrieked like a banshee, “this stuff is made from dead horses!” and started weeping. Dead silence followed. Then came a chorus of cries, snickers, boisterous naying and the kind of pandemonium only a room full of 8-year-olds can generate. I reassured the kids that this was not true at all but it was too late … Mari’s declaration had sparked a mini glue revolt and I scrapped the project for the day.
 
The thing is, I’m well-aware of the old adage about “sending retired horses to the glue factory,” but I always considered it a silly saying. I know that gelatin has animal ingredients in it so I’m curious as to if there’s any truth behind this. Are there horse — or any other animal — ingredients in Elmer’s and other glues?

Hey Wendy,
 
Yikes. Kids these days, eh? Little Mari (sounds like she has a knack for causing a ruckus … sorry couldn’t resist) although on to something, is slightly misinformed. Just be sure not to serve her any Jell-O in the near future or your next class speaker may be a representative from PETA.
 
Glue, historically, is indeed made from collagen taken from animal parts, particularly horse hooves and bones. In fact, the word “collagen” comes from the Greek kolla, glue. This practice has been going on for thousands and thousands of years; it’s not the invention of some enterprising farmer named Elmer who had a few about-to-be-put-down horses on his hands, a knack for organic chemistry and a vat of boiling water. So, yes, as unpleasant to think about as it is, glue can contain animal-based ingredients (nowadays it’s mostly cattle hooves). Adhesive aficionados seem to gravitate towards fish and hide glues. But honestly, I’d be hard-pressed to say that there are many horse-slaughtering glue operations still out there since synthetics are so much cheaper and effective.
 
So what about that bottle of Elmer’s that sent Mari into a tizzy? According to the company, no horse or any other animal is (currently) harmed in the making of their product. Elmer’s Glues, like many commercial “white” glues these days, are 100 percent chemical-based, which, depending on how you look at it, is worse than reusing the body parts of dead ungulates.
 
Reads the Elmer’s website:
 
Elmer's Glues are chemical based. They are made or formulated from chemicals which are synthesized (created by man). These chemicals were originally obtained or manufactured from petroleum, natural gas and other raw materials found in Nature. The exact formula and specific ingredients used in making Elmer's products are considered proprietary information, therefore, we cannot share those with you.
 
I’m not quite sure how to tell you to proceed with this, Wendy. An informative class field trip to a local rendering plant is out of the question and I wouldn’t sit down Mari down for a chat about the environmental ills of petrochemicals. I also can’t imagine a childhood without good, old-fashioned Elmer’s.
 
Sadly, there aren’t a ton of non-synthetic, vegan glues on the market, at least ones that are classroom-friendly. There’s nontoxic, made-in-Italy Coccoina Adhesive Glue Sticks but they can be pricey and hard to come by. Plus, they smell like marzipan so any students already prone to paste eating might be tempted to snack on the craft supplies.
 
I’d say just give it a second try. Kids are fickle and unless Mari really loves horses, she may have already totally forgotten about it.

Then why do they have a cow on the label? Huh?!

Elmer is a great synonyms finder when he's trying to protect it's products. I think you shouldn't believe them.

The best non-toxic, non-animal glue is WELDBOND. I use it always and all ways.

This is not the sticky wicket you might think it is... how about good old fashioned wheat flour paste? Easy to make, archivally sound, plenty sticky for whatever your little darlings are making.

And if they eat it, well, the only ones it'll hurt are the wheat intolerant.

Very interesting. The other point to note is that even though the U.S.'s final few horse slaughter plants have been shut down, there is still a big business in Canada and Mexico, and American horses are still being sent over for rendering. It's an interesting nexus of animal rights and environmental concerns. Some people would clearly rather use petrochemicals than something sourced from a beloved animal, whereas others may take a more lifecycle carbon analysis. Sometimes animal rights and.... More

It's wonderful to hear that Elmer's is no longer using animal products for their glue, however, I must caution that there are still glue factories out there that do. I've witnessed many horse auctions where horses are sold for next to nothing and literally taken off to the glue factory. LIVE horses that no one wants anymore are slaughtered and their parts split up for glue.

I haven't been to an auction in about 5 years... and great strides have definitely been taken since then so I.... More
