Glycolic acid Chemical Properties,Uses,Production

Description

Glycolic acid is the smallest alpha-hydroxy acid (AHA). It is mainly supplemented to various skin-care products to improve the skin’s appearance and texture. It can also reduce wrinkles, acne scarring, and hyperpigmentation. In textile industry, it can be used as a dyeing and tanning agent. It can also be used as a flavoring agent in food processing, and as a skin care agent in the pharmaceutical industry. It can also be added into emulsion polymers, solvents and ink additives to improve flow properties and impart gloss. Moreover, it is a useful intermediate for organic synthesis including oxidative-reduction, esterification and long chain polymerization.

Chemical Properties

Glycolic acid, CH20HCOOH, also known as hydroxyacetic acid, is composed of colorless deliquescent leaflets that decompose at approximately 78° C (172 OF). It is soluble in water,alcohol,and ether.Glycolic acid is used in dyeing, tanning, electropolishing,and in foodstuffs. It is produced by oxidizing glycol with dilute nitric acid.

Uses

Constituent of sugar cane juice.

Definition

ChEBI: A 2-hydroxy monocarboxylic acid that is acetic acid where the methyl group has been hydroxylated.

Uses

In the processing of textiles, leather, and metals; in pH control, and wherever a cheap organic acid is needed, e.g. in the manufacture of adhesives, in copper brightening, decontamination cleaning, dyeing, electroplating, in pickling, cleaning and chemical milling of metals.

Purification Methods

Crystallise it from diethyl ether. [Beilstein 3 IV 571.]
