Elmers glue is PVA (PVAC) based - but has lots of other stuff (tackifiers and solvents), and has a pH of 5 (meaning it is acidic). For book binding, I would definitely recommend using a pH neutral PVA based glue that is specific to book binding. The acid in Elmers has a nice way of breaking down the cellulose in paper over time, and who knows what the other ingredients might do.

Wouldn't that apply to any cellulose product, eg. wood? My mother has a popsicle stick jewellery box I made for her about 40 years ago using Elmer's white glue. Other than re-gluing a couple of the sticks that were knocked off over the years, there is no evidence of any acidic deterioration that I have seen.
Paper is different to wood, it's thinner and heavily processed. L

According to the Material Safety Data Sheet (MSDS) for Lineco pH Neutral PVA Adhesive, its pH is between 4.0 and 6.0, while Elmer's Glue-All is between 4.8 and 5.1 according its own MSDS.
I expect that Elmer's Glue-All is sufficiently "pH neutral" for most purposes.

Jade 403, on the other hand, is 7.1 to 7.3, so which PVA you use *is* important for archival purposes.

So when doing book binding and it says to use PVA glue, I would be just fine using Elmer's?

Possibly, the formulation is basically the same for all PVA glues but the purity may vary due to the manufacturer's quality control process. I have pretty much limited my use of PVA to two brands, Elmer's and Titebond with no discernible difference, except Elmer's seems slightly more viscous than Titebond. I've seen some Chinese made PVAs in the dollar store but never used them, the price difference between them and the Elmer's and Titebond is negligible.

I was just going to say that Elmers is made by a cow. I'm glad you knew the right answer.

Actually, Elmers glue is entirely derived from petroleum products. This is from their FAQ: "Do you use animals when making glue? No, Elmer's does not use animals or animal parts to make glue. Our products are made from synthetic materials and are not derived from processing horses, cows or any other animals. "
