Description: Glycolic acid (or hydroxyacetic acid) is the smallest alpha-hydroxy acid. Due to its excellent capability to penetrate skin, glycolic acid is often used in skin care products, most often as a chemical peel.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
