Fumaric Acid

Molecular Formula : C₄H₄O₄
CAS NO. : 110-17-8
Synonym: Trans-Butenedioic Acid
Solubility : (Unit: g/100g)

Usage of Fumaric Acid:
Fumaric acid is a kind of chemical product which has bacteriostatic and antiseptic function. It can be used as acidulant, acidity regulator, acidifier, thermal-oxidative resist auxiliary, curing accelerant and spice. Fumaric acid has been widely used in producing various carbonic acid drink, wine, concentrated solid drink, ice cream and other cold foods and drink. It can replace malic acid, citric acid, for its acidity degree is 1.5 times of that of citric acid.
Fumaric acid can be used as pharmaceutical intermediate and optical bleaching agent and also can be used in manufacturing unsaturated polyester resin.

Fumaric Acid - CWS

Characteristics of Fumaric Acid - CWS:
Odorless white powder, soluble in ethanol and water
Usage of Fumaric Acid -CWS:
The solubility of fumaric acid-CWS is 65% higher than that of original fumaric acid. Its acidity is 2.5 times of that of citric acid. Better emulsibility, stability. It can take the place of malic acid, citric acid, benzoic acid and widely used in cold drink, potables, alcoholic, marmalade, cake, pickle, noodle, bread, etc.
