Malachite green is also found to be especially active against the fungus Saprolegnia, which infects fish eggs in commercial aquaculture. Despite its name the dye is not prepared from the mineral malachite, and the name just comes from the similarity of color. Also, in 2006 the United States Food and Drug Administration (FDA) detected malachite green in seafood imported into that country for human consumption by China, where the substance is also banned for use in aquaculture. malachite green acidic or basic Manufacturers, Factory, Suppliers From China, With superb service and quality, and an enterprise of foreign trade featuring validity and competitiveness, that will be trusted and welcomed by its clients and creates happiness to its employees. In 2005 eels and fish imported from China and Taiwan were found in Hong Kong with traces of this chemical. bc it stains the MO which is (-) therefore the stain is (+) charged. Malachite green can also be used as a saturable absorber in dye lasers, or as a pH indicator between pH 0.2 - 1.8.

IDENTIFICATION, GENERAL (Packing Group: III), Members Hemoglobin catalyzes the reaction between LMG and hydrogen peroxide, converting the colorless LMG to the chromatic form of malachite green. Leuco-malachite green causes an “increase in the number and severity of changes”. Results showed that the pseudo-second-order reaction model best described the adsorption process with chemisorption being the rate-limiting step. The dyes were used as commercial salts without purification. Lab tests revealed that rats fed malachite green at the concentration of 100 ppb for longer than 2 years showed signs of tumors. This shows that although adducts are formed, they have “little mutagenic or carcinogenic consequence.” Therefore it could be concluded that malachite green caused carcinogenic symptoms but a direct link between malachite green and liver tumor could not be proved. When it is inside the cell, it is then metabolized into a form called leuco-malachite green. Lead Iodide . The effects of malachite green on fish eggs have also been tested and it has been shown that a twofold increase in the concentration of malachite green could lead up to 20 times the mortality rate in rainbow trout eggs[citation needed].
