Bismuth oxychloride is an inorganic compound of bismuth with the formula BiOCl. It is a lustrous white solid used since antiquity, notably in ancient Egypt. Light wave interference from its plate-like structure gives a pearly iridescent light reflectivity similar to nacre, it is known as pearl white. The structure of bismuth oxychloride can be thought of as consisting of layers of Cl−, Bi3+ and O2− ions; these ions are ordered as i.e. with alternating anions and cations. The layered structure gives rise to the pearlescent properties of this material. Focusing on the coordination environment of the individual ions, the bismuth centers adopt a distorted square antiprismatic coordination geometry; the Bi3+ ion is coordinated to four chloride, forming one of the square faces, each at a distance of 3.06 Å from Bi, four oxygen atoms forming the other square face, each at a distance of 2.32 Å from Bi. The oxygen atoms are tetrahedrally coordinated by four bismuth atoms. BiOCl is formed during the reaction of bismuth chloride with water, i.e. the hydrolysis: BiCl3 + H2O → BiOCl + 2 HClWhen heated above 600 °C, BiOCl converts to the Bi24O31Cl10, called the "Arppe compound" which has a complex layer structure.
It has been used in cosmetics since the days of ancient Egypt. It is part of the "pearly pigment found in eye shadow, hair sprays, nail polishes, other cosmetic products". Owing to the plate-like structure of the BiOCl, its suspensions exhibit optical properties like nacre. In cosmetic its name is C. I. 77163. BiOCl exists in nature as the rare mineral bismoclite, part of the matlockite mineral group. An analogous compound, bismuth oxynitrate, is used as a white pigment
