4. It helps to lower the pH level and even kills bacteria,has bacteriostatic and antiseptic function.

5. It can replace hygroscopic acids in dry mixture because it does not dissolve in water.

6. Fumaric acid esters are used to treat psoriasis, as it has been suggested that the condition is caused by an impairment of fumaric acid production in the skin.

7. Fumaric acid is used in the manufacture of polyester resins and polyhydric alcohols and as a mordant for dyes.
