Applications

Glycollic acid 70% solution can be used as cleaning agent. The mixture of glycolic acid 20% solution and formic acid 1% is a highly efficient and low-cost cleaning agent used in air-conditioning, boilers, running piping, electrical plant, dondenser, heart exchanger, etc.

Glycolic acid (or hydroxyacetic acid) is the smallest α-hydroxy acid (AHA). This colorless, odorless, and hygroscopic crystalline solid is highly soluble in water. It is used in various skin-care products.

Glycolic acid is used to improve the skin's appearance and texture. It may reduce wrinkles, acne scarring, hyperpigmentation and improve many other skin conditions, including actinic keratosis, hyperkeratosis, and seborrheic keratosis.

Glycolic acid is used in the textile industry as a dyeing and tanning agent, in food processing as a flavoring agent and as a preservative, and in the pharmaceutical industry as a skin care agent.

Glycolic acid is also a useful intermediate for organic synthesis, in a range of reactions including: oxidation-reduction, esterification and long chain polymerization. It is used as a monomer in the preparation of polyglycolic acid and other biocompatible copolymers.


Packaging

250kg per plastic drum; total 20MT per 20ft container with pallets (without pallets)

 

Storage

It is stable stored at temperature above 10°C(50°F). The storage should be kept warm to maintain temperatures above 10°C(50°F) to prevent precipitation of glycolic acid crystals.
