when a ligand has highly electronegative elements at its ends like O- or NH- etc. it tends to share its electrons by donating them to empty orbitals of the metals and lead to the formation of complexes called ion-association complexes.
when more than one such higly electronegative sites are present in the same ligand (like ETDA,gelatin, ethylene di amine , etc.) these tend to form intra-molecular rings with the
metal atom , these are called chelating agents.

the best way to think of chelation is to think of a crab grabbing something with a claw. that's how edta etc. work with grabbing ions etc. all it does is "clamp" down on the target and hold on with the bonds it creates which is called the ion-association complex. If you need more info either pick up a gen chem text or search wikipedia.

I think my shampoo has a chelating agent in it. But that really doesn't help you, does it?
