DuPont Glycolic Acid has a variety of industrial and personal care applications

Grades of DuPont™ Glyclean®

DuPont™ Glyclean® PV

DuPont™ Glyclean® PV is a high-performance product used in the fabrication process of photovoltaic cell and display devices as an active ingredient for the etching process of crystalline silicon or silicate glass. Glyclean® PV is used in the texturing process of polycrystalline silicon, to improve the surface uniformity, sunlight absorption, and cell efficiency. Glyclean® PV is also used in the silicate glass cutting process to increase etch rate and edge angle with remarkable improvement of uniformity in terms of unique metal chelating and complexing functionality.

DuPont™ Glyclean® AM

DuPont™ Glyclean® AM is EPA registered as a manufacturing product for use as an active ingredient in liquid disinfecting formulations on hard, non-porous surfaces for household, industrial, institutional or commercial premises.  It can also be used in formulating disinfecting cleaners for agricultural premises, and food processing facilities and equipment.  It contains 68% Glycolic Acid and 32% water.

DuPont™ Glyclean® AN

DuPont™ Glyclean® AN is an acrylonitrile purification product with many benefits over acetic acid.  Forming ammonium glycolate as opposed to acetate, it reduces polymerization by scavenging free ammonia at heat transfer surfaces.  A stronger organic than acetic acid, Glyclean® AN cuts cleaning costs by requiring just one third the amount for most applications.

For wastewater systems, lower vapor pressure and higher boiling point improve pre-discharge distillation.  For process equipment, a partition-to-water phase ratio of 21:4, versus 2:3 for acetic, means less corrosion.  Studies show it breaks low-weight polymer so exchangers and columns stay cleaner longer.  With similar handling characteristics as acetic, conversion to Glyclean® AN requires minimal retrofit.
