Applications:
It is widely used in household and industrial cleaning applications. It can be used as preservative in food processing and water treatment industries, pH control and chemical intermediates; it can also be applied as an important additive in many fields, such as metalworking, electro-plating, electropolishing, tanning, spinning, dye printing and so on.

Stability and Storage:
It is stable stored at temperatures above 10°C (50°F). The storage area should be kept warm to maintain temperatures above 10°C (50°F) to prevent precipitation of glycolic acid crystals.
