I'm guessing that when you get a better paste and remove the wheel to replace it, you'll find that stuff separated just like you found it from the tube.
No disrespect intended, but have you not heard of tooth paste from a squeeze tube? (sorry I could not resist that one) Yes, paste can be purchased in tube or tub form.
