Iron(II) oxide III and forms insoluble hydroxides in water. Iron(II) oxide is used as a pigment. It is FDA-approved for use in cosmetics and it is used in some tattoo inks. It can also be used as a phosphate remover from home aquaria. Iron(II) oxide Iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron(III) oxide (ferric oxide). Iron(II) oxide also refers to a family of related non-stoichiometric
10-Methacryloyloxydecyl dihydrogen phosphate 10-Methacryloyloxydecyl dihydrogen phosphate MDP Monomer (10-Methacryloyloxydecyl dihydrogen phosphate) is used for dental adhesive materials. The phosphate monomer was developed by Kuraray co., Ltd. with focus on the dental adhesion technology in 1981. 10-MDP MDP is synthesized according to the following reaction. At first, 10-hydroxydecy methacrylate is synthesized by reaction with methacrylic acid and 1,10-decandiol. Next, phosphoryl chloride is added to 10-hydroxydecy methacrylate, then, the bonding of P-Cl is hydrolyzed. In the late 1970s, tooth adhesion phosphate monomer: 2-methacryloyloxethyl phenyl hydrogen phosphate (Phenyl-P) was developed for tooth substance saving restoration technique. 4-Methacryloyloxyethyl trimellitic acid anhydride (4-META) that adhere to not only
