Essential Details About Sodium Hydroxide

Shipping limitations apply because sodium hydroxide is classified as a "dangerous good" (UN1823) for transportation purposes. Owing to these limitations, if you order a 25KG bag, your product will be delivered via pallet. Please make sure you can accept this delivery method before placing your order. Depending on supply levels, there can be a lengthier wait time if you're trying to buy 25KG in bulk. Please contact us if you have any questions since certain destinations are subject to restrictions. Pop an email to or use our contact form.

In order to cover the higher shipping costs, we have reduced the price of our 25KG bags while maintaining the highest quality of service and product accessibility.

What is Sodium Hydroxide and why is it used in Soap Making?

Sodium Hydroxide, also known as caustic soda or lye, is a chemical compound that is commonly used in soap making. It is a highly alkaline and corrosive substance, but with the right precautions and proper handling, it can be safely used to create high-quality soaps.

Now onto the question of why it's used in soap making. This goes back to the process of saponification - a chemical reaction between an acid (in this case fatty acids from oils or fats) and a base (sodium hydroxide). This reaction results in the formation of soap molecules and glycerol. So essentially, sodium hydroxide acts as a vital catalyst in turning oils into soap.

But you may be wondering, why not just use natural bases like potassium hydroxide instead? Well, while both substances produce similar end products, sodium hydroxide has stronger alkali properties which create harder and more long-lasting bars of soap. Additionally, using sodium hydroxide allows for more control over the final texture and consistency of the soap.

Some may have concerns about using such a strong chemical compound on their skin. However, during saponification most (if not all) of the sodium hydroxide reacts with the fatty acids, resulting in minimal traces left in the final product. In fact, many artisanal soaps use excess oils/fats to ensure complete conversion leaving no residual lye at all.

Furthermore, when done correctly with precise measurements and calculations by experienced soap makers, there should be no excess lye left over in your finished bar. And even if there were any traces present after curing time (4-6 weeks), they would not pose any harm to your skin due to their low concentration levels.

Apart from its role in saponification though, sodium hydroxide also has other benefits for homemade soaps. It helps balance pH levels which makes it gentle on sensitive skin, and it also has strong cleansing properties that effectively remove dirt and oils from the skin.

In conclusion, while sodium hydroxide may seem intimidating to some, it is a key ingredient in soap making for its ability to turn oils into luxurious soaps. As long as proper precautions are taken and precise measurements are followed, using this compound can result in beautifully crafted bars of soap that are safe and beneficial for your skin. Happy soap making!

What is the difference between Lye and Sodium Hydroxide?

Lye solution and sodium hydroxide are often used interchangeably in common language, but there are some key differences between the two. Both are highly caustic substances that have various industrial and household applications, but they differ in their chemical composition and properties.

Firstly, let's break down what exactly we mean by lye solution and sodium hydroxide. Lye solution is a generic term used to refer to any alkaline solution with a pH greater than seven, while sodium hydroxide specifically refers to a compound composed of one atom of sodium, one atom of oxygen, and one atom of hydrogen (NaOH). So while all lye solutions contain some form of base substance, not all of them are pure sodium hydroxide.

One main difference between these two substances is their strength or concentration levels. Sodium hydroxide typically comes in solid or powder form and needs to be dissolved in water to create a lye solution. Depending on the intended use, it can range from 99% pure for industrial purposes to lower concentrations for household cleaning products such as drain cleaners or laundry detergent.

In summary, lye solution is a general term used to describe any alkaline substance while sodium hydroxide refers specifically to a pure compound of one atom each of sodium, oxygen, and hydrogen. Furthermore, while both have similar chemical properties and can be used in similar ways for various applications (e.g., soap making), their concentration levels and handling precautions differ greatly. Understanding these differences will help you choose the appropriate substance for your intended use and handle them safely.

How do I safely handle and store Sodium Hydroxide?

Handling and storing Sodium Hydroxide (NaOH) may seem intimidating, but with the right precautions, it can be done safely. Here are some tips to help you handle and store this caustic chemical in a responsible manner.

Firstly, it is important to note that Sodium Hydroxide is a strong alkali with corrosive properties. It is commonly used in soap making and household cleaning products, as well as in industrial processes such as paper manufacturing. Therefore, it should always be treated with caution and respect.

When handling NaOH, make sure to wear appropriate protective gear such as gloves, goggles, and a lab coat, ensuring skin it covered. This will minimise the risk of accidental contact with your skin or eyes. In case of accidental contact or spillage on your skin or clothing, immediately rinse with water for at least 15 minutes before seeking medical attention. You need to out weigh the water to caustic ratio vastly, as sodium hydroxide reacts with water to create very high temperatures. So over using the water reduces the risk of additional burning and counteracting the chemical reaction.

In addition to wearing personal protective equipment (PPE), always work in a well-ventilated area when using Sodium Hydroxide. This will prevent any potential inhalation of fumes which can irritate the respiratory system.

Now let's talk about storage. As mentioned earlier, NaOH has corrosive properties which means it can react violently when exposed to certain materials like metals or acids. Therefore, it's crucial to store this chemical properly.

The best way to store NaOH is in its original container tightly closed and labelled clearly. Make sure the container is made of compatible material such as polyethylene plastic; avoid using metal containers at all costs.

Furthermore, keep your storage area cool and dry; ideally between 15-25°C. Extreme temperatures or unwanted moisture can cause changes in the concentration of NaOH solutions which may lead to unexpected reactions during use.

Another important aspect of safe storage is keeping Sodium Hydroxide away from incompatible substances like strong acids or oxidizing agents which could potentially cause dangerous reactions if they come into contact with each other.

Lastly, make sure to keep Sodium Hydroxide out of reach of children and pets. This chemical is not only dangerous when handled improperly but can also be fatal if ingested.

In conclusion, handling and storing Sodium Hydroxide safely requires proper precautions such as wearing protective gear, working in a well-ventilated area, and storing it correctly away from incompatible substances. By following these guidelines, you can ensure the safety of yourself and those around you while using this powerful chemical. Stay safe!
