On the Shelf Life of Glycolic Acid
Glycolic acid is common in all kinds of chemical materials and daily use. However, everyone doubts that glycolic acid can deteriorate? What is its shelf life?

The nature of the substance, glycolic acid has active chemical properties. It can cause chemical changes in the air, or in contact with water vapor and oxygen. If stored in an improper environment, temperature and humidity are inappropriate, and light is too exposed, it can promote its deterioration.

As for the shelf life, it depends on various factors. If stored in a cool, dry, dark place, and well sealed, its quality can be maintained for a long time. Generally speaking, unopened glycolic acid is stored according to the appropriate method, and there are often those with unchanged quality for several years. However, once unsealed, it is often in contact with the external environment, and the speed of deterioration increases. Or within a few months, its properties are different from the beginning.

Users should be careful, and when taking glycolic acid, check its shape first. If the color and taste are different, or there is a precipitation or turbidity, this sign of deterioration should not be used. Glycolic acid that has deteriorated is difficult to use, and may be harmful to substances and endanger the human body. Therefore, we know that the quality of glycolic acid is guaranteed, and the preservation method is essential, and users should be discerning and cautious.
