Chemical appearance:
Caustic soda flakes are white translucent solid crystals. These waxy white crystals are odourless. The crystals are soluble in water and glycerol. This is an alkali, which is a combination of sodium cations and hydroxide anions (NaOH).

Chemical application and strengths:

- White Caustic has a number of applications in various industries. Here are some of the most popular ones.

- Caustic soda is an effective alkali base for the above-mentioned processes. It decomposes protein in room temperature and therefore may cause several burns if not well-handled. In addition the crystals are highly soluble in water. This characteristic makes it ideal for use in making of detergents and processes where water is used. In addition, the crystals can be used to dry rooms of moisture due to its anhydrous nature. It readily absorbs moisture in the atmosphere to form hydrates.

In the making of soaps and detergents, sodium hydroxide is used as an alternative to potassium hydroxide. Essentially the saponification process involves the hydrolysis of esters and alkyl halides. However, potassium hydroxide is more soluble in some organic solvents making it the preferred ingredient in the organic process. On the other hand, it is more preferred in the production of synthetic detergents and fatty acids.

Chemical appearance:
Liquid Caustic Soda Lye is basic a solution of sodium hydroxide. Depending on the intended application, it can be diluted to 32% or 50 %. The solution is colourless and does not have any smells. It is a salt formed by the reaction of sodium and water.

Chemical application and strengths:

- The caustic soda solution is a strong base that is used in various applications across various industries. Some major applications include

- The liquid caustic soda is less dangerous compared to the solid form. However, it should still be handled with care as it irritates the skin. In large scale application, PH meters are installed at various applications to monitor PH and avoid leaching. It is therefore, perfectly safe for water and beverage production if used as required.

Chemical appearance:
Caustic soda pearls appear as white spherical or semi-spherical granules with slightly perceptible color. Caustic soda pearls are water-soluble with an exothermic reaction, and they depict stability in normal conditions. Sodium hydroxide is a highly alkaline substance that dissociates completely in water into sodium and hydroxyl ions.

Chemical application and strengths:

- Caustic soda pearls or Sodium Hydroxide is one of the important inorganic materials for various industries all over the world. The major demand for caustic soda is evident in the paper industry for the pulping and bleaching process. Caustic soda is also a crucial raw material in aluminum production for dissolving bauxite ore.

- Caustic soda also finds many uses in the applications for degreasing and treatment of packaging in the food industry. The use of caustic soda is also prominent in chemical processing as a basic feedstock for various downstream products like plastics, solvents, etc.

- Caustic soda pearls also help in engendering the saponification of vegetable oils and fats required for manufacturing soaps. Caustic soda also finds applications in the textile industry for chemical processing of cotton. Most important of all, caustic soda is significantly important for the natural gas industry, where it helps in the production and processing of petroleum products.

- Caustic soda is also important for elution stripping of gold that is adsorbed onto activated carbon. The mixture of caustic soda and cyanide interacts with carbon for extracting gold from the carbon. Special conditions of temperature, pH, and the flow rate of elution are highly important to the effectiveness of caustic soda in elution stripping.

- Caustic soda also finds small-scale applications such as paint stripping, chemical analysis, and aluminum etching. Furthermore, caustic soda is also used in various domestic products such as drain cleaners, oven cleaners, and other home-cleaning products.
