Henry's law states that is is the concentration of a dissolved contaminent in the solvent that lowers the freezing point of water I think that is what you mean rather than the temperature of water). So any salt, and not just NaCl has the samme effect. In fact you may note that calcium chloride is also sold to melt ice in the winter and said to be more efficient. That is because calcium, a 2+ has two times as many mols of ions as Na (a 1+)

Anything dissolved in the water will lower the freezing point of water. I think that's what you meant.
Otherwise, there are chemicals which dissolve endothermically, which will lower the temperature of the water that they are added to.
Just look for compounds with a positive enthalpy of solution value.

salt lowers the freesing temp of water by causing impurities. If you added sugar or even vinigar to the water it would lower the freezing temp. Ammonia lowers the temp of water itself. This is why it is used in refrigerators.
