Glycolic Acid Powder CAS 79-14-1

Details:

1. Introduction

Glycolic acid (GA) is the simplest hydroxy acid. It exists widely in nature, such as sugar cane, sugar beet and immature grape juice, etc., but its content is low, and it coexists with other organic acids, so it is difficult to separate and recover. Glycolic acid powder is manufactured by synthetic way in industrial production.

 

2. Main Functions

2.1. Skin care effect

99% glycolic acid is a good medicine for removing dead skin and hair. It can synthesize fruit acid, which is a raw material for anti-aging and whitening cosmetics, and can achieve the effect of moisturizing and promoting epidermal renewal. The molecular weight of glycolic acid is very small, it can effectively penetrate the skin pores, and solve problems such as skin aging, wrinkles, dark spots, and acne in a short time, so it is unanimously praised by the medical beauty industry.

There's a study has observed the changes of wrinkles before and after 30 patients with glycolic acid (GA) facial peeling treatment.

After 5 treatments in 30 patients, the clinical effective rate was 100.0%, and the markedly effective rate was 40.0%. Two patients had obvious desquamation after skin peeling, which were small scales, which lasted for 3 and 8 days, respectively; 2 patients had small blisters and scabs after peeling, and the scabs were removed spontaneously after 3-4 days. There was no local pigment abnormality, and the patients were all cured at the follow-up 2 weeks later. There were no adverse reactions such as persistent erythema, edema, and scarring.

2.2. Chemical cleaning: 70% GA solution is mainly used as a cleaning agent, 2% GA and 1% formic acid mixed acid is a high-efficiency and low-cost cleaning agent, which can be used as air conditioners, boilers, power plant transmission pipes, condensation It is the main cleaning raw material for boilers, heat exchangers, etc.

2.3. Biodegradable materials: GA is widely used in the preparation of implanted sustained-release drug systems, implanted repair devices, bioabsorbable surgical sutures, artificial bones and organ materials, etc., and has great development prospects. Polylactic acid and polyglycolic acid have become the focus of development in the field of new materials.

2.4. Bactericide: Because glycolic acid contains a special structure of hydroxyl and carboxyl groups, it can form a hydrophilic chelate with metal cations through coordination bonds, so it has a significant inhibitory effect on the growth of iron-oxidizing bacteria. It can be used as a bactericide and can also be used It acts as an inhibitor in the flotation of various ores.

 

2.5. Electroplating surface treatment: Glycolic acid powder can also be used in electroplating industry, sodium and potassium glycolate can be used as electroplating additives, and can also be used as green chemical raw materials for electroplating grinding, metal pickling, leather dyeing and tanning preparations. Glycolic acid is also a complexing agent for electroless nickel plating. It has the advantages of corrosion resistance, fast reaction and good finish. It is the best raw material for improving the quality of electroless nickel plating.

3. Applications

Glycolic acid powder is widely used in daily chemical industry, chemical cleaning industry, raw materials for organic synthesis, electroplating additives; chemical analysis reagents.
