Cl 77289

Chromium hydroxide green, also known as Pigment green 18 or Chromium oxide hydrated, is an inorganic pigment originating from the chromium hydroxide group. Its chemical composition is represented by the formula Cr2O3.3H2O and it is generally known by the code Cl 77289. This pigment is produced in different shades, depending on the particular chemical method of production, but its green colour is most commonly encountered. Due to its high resistance to light and heat and its harmlessness to the human body, this pigment is widely used in many industries.

Cl 77289 finds its main application in the manufacture of cosmetic products, particularly in the field of decorative cosmetics. It is commonly used for colour enhancement in various types of make-up, eye shadows, mascara, lipsticks or nail art. Due to its harmlessness and stability, it is also often used in dermatological and pharmaceutical preparations such as creams, ointments or pastes. Outside the cosmetics industry, it is also used in the production of paints and varnishes for industrial applications and in the construction industry, where Pigment green 18 is used to colour concrete, plaster, paints and ceramics. Due to its properties such as excellent UV resistance, high thermal stability and chemical resistance, it is also occasionally used in the plastics and rubber industries.
