Deicing and anti-icing compositions comprising renewably-based, biodegradable 1,3-propanediol

a technology of anti-icing compositions and biodegradables, which is applied in the direction of non-active ingredients of oil/fat/waxes, plant/algae/fungi/lichens, energy-based wastewater treatment, etc., which can solve the problem of releasing previously fixed co2 into the atmosphere, the unavoidable consequence of biodegradation of glycols derived from fossil-based sources

AI Technical Summary

Benefits of technology

"The present invention is about a deicing or anti-icing composition made of 1,3-propanediol and an aqueous solution. The 1,3-propanediol has a bio-based carbon content of at least 1%. The composition may also contain a surfactant and have low ultraviolet absorption and low concentrations of organic impurities. Additionally, the composition is biodegradable and has an anthropogenic CO2 emission profile of zero. The technical effects of this invention are improved deicing or anti-icing performance with reduced environmental impact."

Problems solved by technology

While biodegradability is an important factor in protecting the environment, biodegradation of glycols derived from fossil-based sources has the unavoidable consequence of releasing previously fixed CO2 into the atmosphere.

Abstract

Disclosed herein are deicing and anti-icing compositions comprising 1,3-propanediol, wherein the 1,3-propanediol in said deicing or anti-icing composition has a bio-based carbon content of about 1% to 100%. In addition, it is preferred that the 1,3-propanediol be biologically-derived, and wherein upon biodegradation, the biologically-derived 1,3-propanediol contributes no anthropogenic CO2 emissions to the atmosphere.
