Sodium Hydroxide, Lye, Caustic Soda
Anhydrous caustic beads are white and spherical. Dry caustic soda has a white color and a microcrystalline structure. It is anhydrous, hygroscopic (attracting moisture) and deliquescent (dissolving in moisture absorbed from the atmosphere) and reacts with carbon dioxide in the air to form sodium carbonate.
Common Uses :
The host of different uses of anhydrous caustic beads is derived mainly from its reactivity as a strong alkali. With all downstream applications, appropriate registrations and/or approvals may be required.
Possible uses are described below:
 Petroleum Exploration -  anhydrous caustic beads is used as a treating agent in oil well drilling fluids. It is used to increase viscosity, which prevents heavier materials from settling.
 Food and Dairy -  anhydrous caustic beads is used in various food processing methods. This includes washing and chemical peeling of fruits and vegetables, poultry, soft drink, chocolate and cocoa processing, and thickening ice cream.
 Textile Treatment -  anhydrous caustic beads is used as an aid in scouring, bleaching and neutralizing during textile processing.
 Chemical Production - Besides its use as a reactive intermediate and catalyst in chemical production, anhydrous caustic beads is also used in chemical processing plants for scrubbing and drying.
 General and Industrial Cleaning - A strong base like anhydrous caustic beads can be used as an alkali source in cleaning agents. It can dissolve grease, oils, fats and protein based deposits. Refer to the Safety Data Sheet (SDS) for additional information and before handling this material. A caustic soda solution with added surfactants stabilizes dissolved substances and prevents re-deposition. caustic soda is also used, for example, to clean and prepare sheet steel in galvanizing plants, and caustic soda is the chief ingredient for drain pipe cleaners.
 Soap and Detergent -  anhydrous caustic beads saponifies fats into water-soluble sodium soaps.
 Biodiesel and Bioethanol - In manufacturing biodiesel and bioethanol,  anhydrous caustic beads is used as a catalyst for the transesterification of methanol and triglycerides, and used for pH adjustment and formation of in situ sodium methylate. Anhydrous is required, because the presence of water would form soap.
 Metal Cleaning -  anhydrous caustic beads can clean metals by saponifying surface oils to create a thin soapy layer. In certain types of metals it can be used to etch the surface, an important preparatory step in many welding or painting applications.
 General Industrial -  anhydrous caustic beads is used in a variety of plants making products ranging from glue, gelatin, grease and cosmetics to dry batteries, agricultural products, and paint and varnish removers.
