Abstract
Prezenta inventie se refera la un procedeu de obtinere a pigmentului cosmetic verde pe baza de oxihidrat de crom, prin omogenizarea unui amestec de K2Cr2O4 : H3PO3 cu puritate ridicata (minimum 99%) într-o proportie de 1:4 parti amestecul omogenizat se calcineaza la o temperatura de 600...800 degree C, timp de 30...60 min, dupa care are loc calirea produsului cu o suspensie de stearat de magneziu sau zinc la o temperatura de 80...100 degree C, se spala prin decantari succesive cu apa la temperatura de 50...60 degree C, se separa prin filtrare, se usuca la 120 degree C si se macina.
