Use of Glycolic Acid
1, the chemical cleaning: 70 percent glycolic acid solution is mainly used as cleaning agents, 2% glycolic acid and 1% of formic acid mixture is a high efficiency, low cost of cleaning agents can be used as air-conditioning, boiler, power plant pipeline , condensers, heat exchangers and other major cleaning materials.
2, biodegradable materials: Widely used in the preparation submerged in vivo drug release systems, submerged repair equipment, bio-absorbable surgical sutures, artificial bones and organs materials, very development prospects. Polylactic acid and polyglycolic acid has become a new field of materials development focus.
3, fungicides: As a special structure containing glycolic acid hydroxyl and carboxyl groups, with the metal cation formed by hydrophilic chelate ligand bond, so the growth of iron-oxidizing bacteria significantly inhibited, can be used as fungicides, It can also be used in a variety of ore flotation in as inhibitors.
4, household chemicals: 99% Glycolic acid is good effect to remove dead skin and hair drug can be synthesized anti skin aging, whitening cosmetic ingredients acid, can reach moisturize skin, promote skin update of efficacy. The molecular weight of glycolic acid is very small, it can effectively penetrate skin pores, in short span of time skin aging, wrinkles, dark spots, acne and other problems, so it is unanimously respected medical field.
5, plating surface treatment: glycolic acid can also be used in electroplating industry, glycolic acid sodium salt, potassium salt used as a plating additive, but also for plating grinding, metal pickling, leather dyeing and tanning agents of green chemical raw materials. Glycolic acid is electroless nickel complexing agent, corrosion resistant, fast response, good finish, etc., it is to improve the quality of electroless nickel best formulation materials.
In addition, glycolic acid can be used in the textile industry, dyeing wool and cellulose fiber fabric crosslinking coupling agent or a carboxyl group-containing fabrics crosslinking catalysts; also be used as an adhesive, oil demulsifiers, welding and coating ingredients and synthesis of a variety of pharmaceuticals, pesticides and chemical additives.
