Sodium hydroxide is a accepted able abject acclimated in industry. Around 56% of sodium hydroxide produced is acclimated by industry, 25% of which is acclimated in the cardboard industry. Sodium hydroxide is aswell acclimated in the accomplish of sodium salts and detergents, pH regulation, and amoebic synthesis. It is acclimated in the Bayer action of aluminium production.In bulk, it is a lot of generally handled as an aqueous solution, back solutions are cheaper and easier to handle.

Sodium hydroxide is acclimated in abounding scenarios area it is adorable to access the alkalinity of a mixture, or to abrogate acids.

For example, in the petroleum industry, sodium hydroxide is acclimated as an accretion in conduct mud to access alkalinity in bentonite mud systems, to access the mud viscosity, and to abrogate any acerbic gas (such as hydrogen sulfide and carbon dioxide) which may be encountered in the geological accumulation as conduct progresses.

Poor superior awkward oil can be advised with sodium hydroxide to abolish sulfurous algae in a action accepted as abrasive washing. As above, sodium hydroxide reacts with anemic acids such as hydrogen sulfide and mercaptans to crop non-volatile sodium salts, which can be removed. The decay which is formed is baneful and difficult to accord with, and the action is banned in abounding countries because of this. In 2006, Trafigura acclimated the action and again dumped the decay in Africa.
