Sodium picramate or sodium picramate is an organic compound composed of sodium and picric acid. It is a brown to orange crystalline substance that is highly soluble in water and is active in slightly acidic environments. Structurally, it consists of nitro groups attached to an aromatic ring, which is further linked to a carboxylate salt. Sodium picramate has the chemical formula C6H2N3NaO7 and its molecular weight is 245,08 g/mol.
Although Sodium Picramate is a hazardous and potentially toxic substance, it has been used extensively in the cosmetic industry, specifically in hair dye products. Due to its ability to produce stable and desirable hair shades, it has been widely used worldwide. Its use in cosmetic products is currently banned in the European Union due to the potential health risks associated with its use. It can cause irritation or even an allergic reaction at the point of application. Despite this, it is still legally used in some countries, such as India.
