Application of Maleic Acid Anhydride

Maleic Anhydride is used in the formulation of resins. Exposure to maleic anhydride may occur from accidental releases to the environment or in workplaces where it is produced or used. Acute (short-term) inhalation exposure of humans to maleic anhydride has been observed to cause irritation of the respiratory tract and eye irritation.Chronic (long-term) exposure to maleic anhydride has been observed to cause chronic bronchitis, asthma-like attacks, and upper respiratory tract and eye irritation in workers.In some people, allergies have developed so that lower concentrations can no longer be tolerated.Kidney effects were observed in rats chronically exposed to maleic anhydride via gavage (experimentally placing the chemical in the stomach). EPA has not classified maleic anhydride for carcinogenicity.
As a new generation of food acidity regulator, Maleic Acid Anhydride is known as “best food acidity regulator” in biological and nutritional fields. It is widely used in foods such as wines, beverages, fruit juices and chewing gums. It is not only the third food acidity regulator coming after citric acid and lactic acid, but also one of the biggest and most promising organic acids in food industry across the current world. Maleic Acid is capable of gelatinating pectin and therefore can be used for making fruitcakes, jelly fruit juice, puree, etc.
Maleic Acid contains natural skin moisturizing elements. This enables it to dissolve “sticky matters” between dry scale-like dead cells easily, so as to smooth wrinkles on skin and make the skin tender, white, bright, clean and elastic. For this reason, Maleic Acid is very popular for its use in cosmetic formulae. Maleic Acid also can be used as one of the raw materials for synthesizing disincrustant and fluorescent whitening agent. Polyester and alcohol acid resin, which are produced by using malic acid, are plastics that can be used for special purposes. Maleic Acid Anhydride also can be used as an industrial cleaning agent, resin curing agent, synthetic material plasticizer, feed additive, etc.
