Minerios Ouro Branco Magnesium Silicate is known as talc, a mineral of inorganic constitution, chemically inert, extracted from deposits and processed in different granulometric ranges according to the desired application. It is presented in lamellar crystalline form, giving the mineral softness to the touch. Magnesium Silicate is White powder until slightly creamy or grayish, fine, odorless, insoluble in water.

Minerios Ouro Branco Agalmatolite is a mineral of inorganic constitution basically composed of aluminum silicate, chemically inert, white powder until slightly creamy or grayish, fine, odorless, insoluble extracted from deposits and processed in different granulometric ranges according to the desired application. It is presented in lamellar crystalline form.

Minerios Ouro Branco Mica is a mineral of inorganic constitution, chemically inert, extracted from deposits and processed in different granulometric ranges according to the desired application. It is presented in monoclinic crystalline form. Mica is white to slightly grayish powder, odorless, insoluble in water.

Minerios Ouro Branco Precipitated Calcium Carbonate is chemically inert and is obtained by reacting a solution of calcium chloride with a solution of sodium carbonate, or by passing carbon dioxide through a suspension of lime milk. It is presented in medium, light and extra light types, differentiated only by granulometry, with the medium being the thickest and the extra light being the finest. Precipitated Calcium Carbonate is white, fine, odorless, insoluble, light, porous powder with high oil absorption.

Minerios Ouro Branco Calcined Kaolin 0B-2940 is a synthetically modified mineral, manufactured from the calcination of natural kaolin (aluminum silicate). After the calcination process, its crystalline form is modified due to the loss of crystalline water from the molecule, leaving the material whiter, more opaque and abrasive. Inorganic material, chemically inert and benefited in low granulometry.
