PRODUCT INTRODUCTION
description
Glycolic acid is a 2-hydroxy monocarboxylic acid that is acetic acid where the methyl group has been hydroxylated. It has a role as a metabolite and a keratolytic drug. It is a 2-hydroxy monocarboxylic acid and a primary alcohol. It is functionally related to an acetic acid. It is a conjugate acid of a glycolate.
