So thymol goes a long way. 10g is not expensive, either. And neither is methylated alcohol, tho couldn't one use isopropyl?

It is interesting that Michael asked about using glyoxal as a preservative, because I never heard of it being that, and also, it hardens gum. But for some unknown reason they did use formaldehyde as a preservative in gum back in the day. Seems so strange to me.
