I have poured my finished liquid soap into glass bottles. The strangest thing, when I go to tighten the pump it slowly unwinds by itself. Practically, completely loose. I tried a different bottle and pump and same thing. However when I tried it when the bottle was EMPTY the pump completely closed tight and did not loosen. So Im wondering if soap gives off a gas thats trying to expand and wont let the pump stay put or could it be the viscosity trying to push it up?

Any ideas or input would be appreciated.
