General description

Glycolic acid (Hydroxyacetic acid) is an α-hydroxy acid. Glycolic acid solutions having concentration of 70% and pH range of 0.08 to 2.75 are widely employed as superficial chemical peeling agents. Various oligomers or polymers of lactic and/or glycolic acid (low molecular weight) have been prepared. Glycolic acid can be determined via plant tissue coupled flow injection chemiluminescence biosensors, which can be used both as a plant-tissue based biosensor and chemiluminescence flow sensor.

Application

Glycolic acid (Hydroxyacetic acid) has been used in the preparation of PLGA-PEG-PLGA copolymer (PLGA = poly(lactic/glycolic, PEG = polyethylene glycol).
