Detoxification method for obtaining a zinc containing pigment compound with no ecotoxicity

A detoxification method for obtaining a pigment compound free from acute and chronic aquatic ecotoxicity, the method comprising mixing at least one zinc-based component with good anti-corrosive properties but high toxicity, such as:

• zinc metal powder, or zinc oxide or hydroxide, or phosphate, borate, stearate, laurate, carbonate, hydroxycarbonate, polyphosphate, phosphite, pyrophosphate, phosphonate, silicate or ferrite, with at least one phosphate or hydrogen phosphate of the following type:
• magnesium, which can be MgHPO4.3H2O or Mg3(PO4)2.5H2O;
• sodium, which can be Na3PO4.10H2O or Na3PO4,12H2O or Na2HPO4.7H2O or Na2HPO4.12H2O;
• potassium, which can be K3PO4 or K2HPO4;
• calcium, which can be CaHPO4.2H2O or Ca3(PO4)2;
• strontium, which can be SrHPO4 or Sr3(PO4)2;
• aluminum AlPO4;
• ammonium, which can be (NH4)3PO4.3H2O or (NH4)2HPO4;
• organic, which can be of guanidine type,
• or any other compound based on said cations Mg, Ca, Sr, etc, such as carbonates, oxides, silicates, phosphites, pyrophosphates or phosphonates, said phosphates or hydrogen carbonates or carbonates or oxides or silicates or phosphites or pyrophosphates.
