Abstract
A detoxification method for obtaining a pigment compound free from acute and chronic aquatic ecotoxicity by mixing at least one zinc-based component with good anti-corrosive properties but high toxicity-with a phosphate or hydrogen phosphate of a magnesium, sodium, potassium, calcium, strontium, aluminum, ammonium, or organic type or any other compound based on such cations, such as carbonates, oxides, silicates, phosphites, pyrophosphates or phosphonates, said phosphates or hydrogen carbonates or carbonates or oxides or silicates or phosphites or pyrophosphates freed from toxicity enabling a very considerable reduction of the toxic power of said zinc-based component, while maintaining the good anti-corrosive properties thereof.
