Product Application Of Sodium Hydroxide 1310-73-2

Sodium hydroxide (NaOH) is one of the most useful industrial sodium compounds. It is also known as lye or caustic soda and is one of the strongest base alkalis (high pH value) on the household market. It is used as a drain and oven cleaner, and it saponifies fats in the manufacture of soap. It must be used with care because it is also capable of producing serious skin burns.
Caustic soda is one of the most widely usedchemicals. It is used to neutralize acids; tomake sodium salts; to precipitate metals astheir hydroxides; in petroleum refining; in thesaponification of esters; in the treatment ofcellulose, plastics, and rubber; and in numeroussynthetic and analytical applications.
Sodium hydroxide is used to adjust a product pH to make it more acceptable to the skin. It is commonly referred to as caustic soda, and often serves as a chemical reagent when making soap. If too concentrated it may cause severe skin irritation.
