Industrial Applications

Industrial Cleaning & Descaling

Effective descaler for boilers, heat exchangers, and cooling towers. Removes calcium, iron, and mineral deposits without damaging metal surfaces.

Oil & Gas Well Stimulation

Acidizing agent for carbonate and sandstone formations. Slower reaction rate than HCl allows deeper penetration in matrix acidizing.

Personal Care & Cosmetics

Alpha-hydroxy acid (AHA) in chemical peels, exfoliants, and anti-aging skin care formulations. Promotes cell turnover.

Textile Processing

Dyeing auxiliary and pH regulator in textile finishing. Improves dye uptake and fabric hand.

Food Processing Equipment

USDA-approved cleaner for food-contact surfaces. Removes mineral scale and biofilm from dairy and beverage equipment.

Polymer Synthesis

Monomer for biodegradable polyglycolic acid (PGA) and PLGA copolymers used in medical sutures and drug delivery.
