I'm sure it would be quite rare to fight in a clean-room where such a tactic would be necessary, but not to worry... even in conditions free from dirt and dust, you can still get several hits in by converting your ordinary EDC PocketSand™ into earth-shot.

If we're talking fullmetal alchemist rules, it's pretty clear that transmutation doesn't change the atomic make-up of a thing. Just the chemical bonds and intermolecular forces, combined with moving the bits around following a formula. However, you could turn fat into a hydrogen-propelled diamond bullet.

Bonds take energy to break and make. Some is released when they break. And those forces take energy to overcome.
