I am with you on the chemistry just not sure how long it had sat with water and less mixture of ingredients. And like you said was not fluffy. But thought I would throw it out there. It is perplexing but I am going to go with that hose makeup must not gel well (pun intended) with the flavor that was in there before. if it was located other places might think otherwise.
