Abstract
The present disclosure relates generally to deicer compositions comprising a liquid deicing agent which is as an aqueous solution of a deicing salt and additives that provide reduced corrosiveness with reduced biochemical oxygen demand. Aspects of the disclosure are particularly directed to use of the deicer composition as a liquid deicer or an anti-icer. The deicer composition can further include a solid deicing agent such as sodium chloride, where the liquid deicing agent and additive form a pre-wetting agent when mixed with the solid deicing agent to form a pre-wetted deicer.
Claims13
A deicer composition comprising:
- a. a liquid deicing agent, wherein the liquid deicing agent comprises an aqueous solution of a deicing salt or liquid bittern comprising magnesium chloride;
- and
- b. a corrosion inhibiting additive of about 0.05% to about 0.5% by weight, wherein the corrosion inhibiting additive is sodium gluconate;
- and
- c. a viscosifying additive that is xanthan gum.
