Maleic Acid, also known as Toxolic Acid, Maleinic Acid, and cis-Butenedioic acid has the chemical formula C4H4O4. It appears as a colorless crystalline solid possessing a characteristic repulsive taste with a faint odor. It is soluble in Water, Acetone, and Ether. It is used as a raw material for the production of various chemicals for the dyeing and finishing of natural fibers. It is prepared by the hydrolysis of Maleic Anhydride. Purified Grade, also known as Pure or Practical Grade, refers to those high-purity compounds that do not fulfill the ACS, the USP, or the FCC grade requirements.

Questions & Answers

  • Hello, I work for a hair company and have been testing Maleic Acid as a hair smoothing treatment. We are close to finishing the product and are estimated to be purchasing anywhere from 6,050 kg (6 tons - 22 tons) annually, but we would purchase these in increments throughout the year. Could you please send tier pricing and shipping cost to Tennessee? Thank you!!
