Caesium hydroxide is a chemical compound consisting of an atom of caesium and a hydroxide group (also known as hydroxyl). It is a powerful base, much like other alkali metal hydroxides such as sodium hydroxide and potassium hydroxide. In fact, caesium hydroxide is powerful enough to quickly corrode through glass.
Due to its high reactivity, caesium hydroxide is extremely hygroscopic. Laboratory caesium hydroxide is typically a hydrate.
Cesium hydroxide is an aqueous solution. Strongly corrosive. Harmful to skin and eyes. Used in electric storage batteries.

fatty alcohols use


Fatty alcohols mainly for the production of detergent and surfactant. They are cosmetics, food and
industrial solvent component. Because of natural water oil bisexual,  fatty alcohols can be used as
non-ion surface active agent, can also be used in cosmetics and the food industry emulsifier, lubricants
and a thickening agent.
