Infobox references. Glycolic acid (or hydroxyacetic acid; chemical formula HOCH2CO2H) is a colorless, odorless and hygroscopic crystalline solid, highly soluble in water. It is used in various skin-care products. Glycolic acid is widespread in nature. A glycolate (sometimes spelled "glycollate") is a salt or ester of glycolic acid.
Polyglycolide or poly (glycolic acid) (PGA), also spelled as polyglycolic acid, is a biodegradable, thermoplastic polymer and the simplest linear, aliphatic polyester. It can be prepared starting from glycolic acid by means of polycondensation or ring-opening polymerization. PGA has been known since 1954 as a tough fiber -forming polymer.
Alpha hydroxycarboxylic acid. Alpha hydroxy carboxylic acids, or α-hydroxy carboxylic acids (AHAs), are a group of carboxylic acids featuring a hydroxy group located one carbon atom away from the acid group. This structural aspect distinguishes them from beta hydroxy acids, where the functional groups are separated by two carbon atoms. [ 1 ]
Hamden and other dermatologists agree that the list of benefits of glycolic acid is extensive. "Glycolic acid enhances skin shedding and helps correct skin discoloration," began Dr. Hamden.
PLGA, PLG, or poly (lactic-co-glycolic) acid (CAS: 26780-50-7 ) is a copolymer which is used in a host of Food and Drug Administration (FDA) approved therapeutic devices, owing to its biodegradability and biocompatibility. [1] PLGA is synthesized by means of ring-opening co-polymerization of two different monomers, the cyclic dimers (1,4 ...
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Hydantoin, or glycolylurea, is a heterocyclic organic compound with the formula CH 2 C (O)NHC (O)NH. It is a colorless solid that arises from the reaction of glycolic acid and urea. It is an oxidized derivative of imidazolidine. In a more general sense, hydantoins can refer to groups or a class of compounds with the same ring structure as the ...
Thioglycolic acid (TGA) is the organic compound HSCH 2 CO 2 H. TGA is often called mercaptoacetic acid (MAA). It contains both a thiol (mercaptan) and carboxylic acid functional groups. It is a colorless liquid with a strongly unpleasant odor. [4][5] TGA is miscible with polar organic solvents. [6][7]
