Ice melt blends are growing in popularity because they are cheaper than 100 percent calcium or magnesium-based chloride products. Blends consist of a mixture of chemicals, for example, magnesium chloride mixed with sodium chloride.

Because of the mixture, products may make misleading claims about the product's effectiveness. For example, rock salt only works to about 15 degrees Fahrenheit, but magnesium chloride works to minus 15 degrees Fahrenheit. A blend of these two, however, may claim it works to the colder temperature, which is inaccurate and misleading.

Some manufacturers have begun disclosing ingredients on packaging, brochures or websites. If end users know what is in the ice melt blend, they will be able to make educated purchases and choose a product that will work for their particular circumstances.
