    Description

    Caustic Soda, or lye, is an alkali used in soap making. It is also known as sodium hydroxide and has the chemical formula of NaOH. Lye reacts with the fats in oils to produce an opaque or cloudy, hard soap. It is all consumed in the chemical reaction and none remains once the soap is produced.

    98.5% minimum purity.

     

    Uses

    • Sodium Hydroxide is known to help manufacture a variety of medicines and pharmaceutical products, from common pain relievers like aspirin, to anticoagulants that can help to prevent blood clots, to cholesterol-reducing medications.
    • Caustic Soda (sodium hydroxide) is a versatile alkali. Its main uses are in the manufacture of pulp and paper, alumina, soap and detergents, petroleum products and chemical production. Other applications include water treatment, food, textiles, metal processing, mining, glass making and others.
    • Sodium Hydroxide is used in several food processing applications, such as curing foods like olives or helping to brown Bavarian-style pretzels, giving them their characteristic crunch. Sodium hydroxide is used to remove skins from tomatoes, potatoes and other fruits and vegetables for canning and also as an ingredient in food preservatives that help prevent mould and bacteria from growing in food.
     
    Storage: Caustic soda should be stored under dry and cold spaces well-ventilated in order to avoid dust forming and spreading. Never store caustic soda together with other group of materials such as: acids and ammonium salts.
    Caustic Soda is not degraded by temperature changes. However, when exposed to cold temperatures, the product viscosity will increase, making it difficult to pump.
