Shipment / Storage
White deliquescent crystals or lumps, or liquid. May be shipped in steel drums. Drums should be strong and airtight, as the substance absorbs water and carbon dioxide from the air. In liquid form this commodity requires careful handling, and is usually carried on deck only. It attacks organic matter and in the presence of moisture is corrosive to aluminium and zinc. If drums arrive holed due to rough handling, the contents may be found to be slightly discoloured, freely deliquescing and contaminated, having absorbed moisture and carbon dioxide from the atmosphere. That portion which may have deliquesced is good caustic liquor and may be used for its original purpose. In damaged condition it may still be used for certain detergent purposes. Damaged drums should be reconditioned as soon as possible after arrival, to prevent further exposure.
In bulk; stainless steel is suitable for handling caustic soda up to 50% maximum concentration at 65-75°C. At higher concentrations, e.g. 73% which necessitates a temperature of 100-110°C to maintain the liquid state, stainless steel has inadequate corrosion resistance and pure nickel is required. Stainless steel is susceptible to stress-corrosion cracking and also to general corrosion in high-temperature concentrated caustic. For this reason pure nickel is generally specified for heating coils, even in tanks for 50% caustic.
Store in cool, dry conditions in well sealed containers. Keep a long distance from fire and heat, the humidity is no more than 85%. Package should be sealed and dry. Avoid storing the goods together with acid and flammable, combustible products.

GUIDE TO CAUSTIC SODA
“Caustic soda” is a term that might be unfamiliar to those who haven’t worked with industrial chemicals. However, it is a substance used either as an ingredient or in the process of manufacturing dozens of household products (such as body soap, detergents and drain cleaners). Often referred to by its household name of “lye,” which literally means “wash stuff” in Old English, caustic soda has probably been used since the time of the ancient Babylonians and Egyptians, who used it in saponification (the soap-making process).
WHAT IS CAUSTIC SODA
Caustic soda is a relatively simple man-made chemical compound. It is comprised of one sodium (Na), one oxygen (O) and one hydrogen (H) atom, which is why it’s also referred to as sodium hydroxide bearing the chemical symbol “NaOH." Caustic soda is probably the lesser-known product of the Chloralkali process, which is the electrolysis procedure used to free chlorine (Cl) from the sodium chloride (NaCl) found in salt brine. When chemical manufacturers produce chlorine, they also end up producing a comparable amount of caustic soda, which is in many ways as useful as its chemical counterpart.
It is important to recognize that the terms “caustic soda,” “sodium hydroxide” and “lye” all refer to the same chemical compound of NaOH. These terms are used interchangeably throughout the industry and throughout this guide.
Caustic soda is a highly corrosive base or alkaline chemical widely utilized in several different industries. Some common uses include organic chemical production, cosmetic production, soaps & detergent production, paint manufacturing, paper and cellulose, textile bleaching, glass and ceramic manufacturing, food processing, manufacturing rayon, fuel cell production, water treatment, and plumbing (drain cleaners often contain lye).
Caustic soda can cause severe burns to the skin, so it may seem counterintuitive to use lye for making soap. However, sodium hydroxide is one of the few inorganic materials allowed by the USDA in the manufacture of organic soaps. The United States Department of Agriculture (USDA) maintains strict rules over many products grown, raised and produced for human consumption.
The regulations are even more rigorous when the USDA allows a product to bear the distinctive green and white USDA Certified Organic seal on its packaging. Although caustic soda is in no way organic (it’s a man-made chemical product that results from the breaking up of salt molecules), the USDA makes an exception in the production of organic soap. This is because sodium hydroxide is necessary to the chemical reaction that produces soap.
When combined with oils or fats in the saponification process, the caustic soda compound is transformed during the reaction to make the soap safe to use. While the soap acquires some of the atoms once existing in the caustic soda molecule, they are no longer part of the sodium hydroxide compound: the sodium hydroxide and its corrosive properties are gone.
CAUSTIC SODA USEFUL AS A CHEMICAL
In its natural room-temperature state, caustic soda is a solid, but since it readily dissolves in water, it is often sold and transported as a solution of varying concentrations. When caustic soda is mixed with water or an acid, there is a strong exothermic reaction where heat is released, which can be used as a source of energy to trigger other chemical processes. In many lye-related chemical reactions (as was mentioned with soap) caustic soda gives up its sodium, hydrogen and oxygen atoms to help form new chemical compounds.
In situations where a corrosive substance is required, like for a drain blockage, caustic soda will work to dissolve the organic materials but will leave the PVC pipes intact. Sodium hydroxide is also used in the production of soft drinks, ice cream and food dye. The corrosive and toxic properties of caustic soda disappear in these processes such as the case with soap above.
It’s important to note that sodium hydroxide is not safe for direct consumption. It should never be ingested and can cause severe injury or death. Food companies rigorously train their employees in the safe use of sodium hydroxide in chemical food preparation processes, and the end products are tested before being placed on the market.
TRANSPORTING CAUSTIC SODA
The transportation of hazardous materials including caustic soda, is subject to overlapping federal, state and local laws and regulations, as well as international regulations. In addition to the legal requirements for transportation of hazardous materials, the laws of nature also place numerous de facto restrictions on the way sodium hydroxide can be safely packaged for transport.
For instance, caustic soda can corrode or react with aluminum and shed hydrogen atoms which becomes an explosive hydrogen gas. Caustic soda should never be stored in aluminum containers for transport or storage. Other metals that interact with sodium hydroxide to produce hydrogen include magnesium, zinc, tin and chromium; caustic soda should never be kept in containers constructed of any of these materials.
Caustic soda doesn’t react with stainless steel making stainless steel drums, tanks and pipelines the standard in the industry. However, caustic soda does interact with some plastics and can corrode the walls of containers or bags constructed of plastic causing dangerous leaks or spills. For this reason, high-density polyethylene (HDPE) barrels and containers are used for packaging.
As was previously mentioned, caustic soda releases thermal energy when mixed with water. For this reason, dry caustic soda should be in airtight containers to prevent moisture from reaching the material. Caustic soda should not be packaged in paper or cardboard, as those materials tend to be both porous and susceptible to combustion. Liquid sodium hydroxide can be transported in tanks, drums or through pipelines. The same restrictions regarding packaging and container materials apply when caustic soda is being transported in its solid state.
CLEANING A CAUSTIC SODA SPILL
Despite the heavy regulation governing chemical manufacturers and transporters along with the extraordinary care they take in handling hazardous materials like caustic soda, spills and other accidents can occasionally occur. As corrosive to biological materials as sodium hydroxide is (coupled with the fact that there are several substances it reacts with) it is essential to know how to properly clean a caustic soda spill.
If you haven’t been trained to handle a caustic soda accident, clear the area and contact emergency responders to inform them of the size of the spill, the location and other potential hazards in the area. If you have been trained to clean up caustic soda spills, you can follow this clean-up checklist:
- Evacuate and seal the area of the spill
- Wear protective clothing and equipment
- Follow guidelines for liquids and solids
- Venilate and wash once the spill is cleaned
SKIN OR EYE CONTACT WITH CAUSTIC SODA
Wearing the proper safety equipment should significantly reduce the occurrence of skin or eye contact. Because of the extremely corrosive nature of caustic soda, it’s essential to have a plan in place to deal with this contingency.
Time is of the essence when it comes to mitigating caustic soda injuries. It is best to contact emergency rescue personnel immediately after the chemical is removed but not before attempting to remove the chemical first. Do not use vinegar to neutralize the effects of human contact with caustic soda. The acid in vinegar will interact with caustic soda creating a harmful chemical reaction.
Dry caustic soda on skin
Remove as much of the substance as you can with a brush or dry rag. Remove any contaminated clothing or jewelry and wash the affected area for 30 minutes. Remember, mixing caustic soda with water can trigger a thermal reaction and can create a corrosive solution. Ensure all the material is off your skin and do not initially use a wet rag.
Liquid sodium hydroxide solution on skin
Use a dry towel to absorb as much of the material as possible. Remove contaminated clothing or jewelry. Wash the affected area for 20 minutes once it is completely removed.
