In general, agarose gel solubilization can be done with chaotropic
salts such as NaI, sodium perchlorate, or guanidine HCl. These also
work well in conjunction with silica-based binding resins because DNA
binding to silica is promoted in high salt.  I doubt the company will
tell you exactly what is in their buffer, but it is likely similar to
one the salts I mentioned, possibly with additives added as a
stabilizer or other use.
