Abstract
Prezenta inventie se refera la un procedeu de obtinere a pigmentului cosmetic verde pe baza de oxid de crom, prin omogenizarea unui amestec de CrO3 : H3BO3 : S cu puritate ridicata (minimum 99%) într-o proportie de 1:4:0,25 parti, calcinare la o temperatura de 900...1050 degree C, timp de 30...60 min urmat de cplire în suspensie de stearat de magneziu sau zinc la o temperatura de 80...10 degree C, spalare prin decantari succesive cu apa la temperatura de 50...60 degree C si separare prin filtrare si uscare la 120 degree C si macinare.
