Pure Lye

Sodium hydroxide, also known as Caustic Soda or Lye, is a product that is used in the creation of soap, detergent, paper, textiles and drinking water. It is a chemical base and comes packaged as a white solid.


Sodium Hydroxide (Lye) – Uses and Benefits


Having become an incredibly versatile and useful ingredient in everything from food preparation to drain cleaning, it’s no wonder that the world produced 60 million metric tons of sodium hydroxide in 2004. A brief overview of the many uses include:

Food – It can be used to wash or chemically peel fruits and vegetables. Furthermore, it is often used to soften foods like olives or baked goods.

Cleaning – In liquid form, it is used to de-clog drains, dissolve metals and strip paint off a surface. It can also be used to de-grease stainless steel and glass bake ware.

Hair – In liquid form, it is mixed with other ingredients to create a hair straightening substance (often referred to as a “relaxer”).

Tissue – It is often used to dissolve tissue, specifically to break down the tissue of dead animals in carcass removal.

Paper – It is a key ingredient in the creation of paper from wood pulp.

Soap – Typically for cold-process soap making, lye is essential. It can also be used in hot-process soap making when mixed with the appropriate fat and oils. Caustic soda (lye) creates a chemical reaction known as saponificiation. This process is what breaks down the oils and turns them into soap.


History of Sodium Hydroxide

Ancient Egyptians and Babylonians used a form of lye (using ash) around 4,800 years ago and recorded it’s use on a clay tablet. For much of history, water was run through wood ash then mixed with animal fats in a primitive attempt at soap making. Lye wasn’t truly identified and understood until Sir Humphry Davy discovered it in 1807. At first, believing it was one of the basic elements; he later went on to discover sodium.

The term “lye” was an old English word meaning ‘wash stuff’. Original lye soap was very harsh and often left the users skin red after use. This was because too much lye was used in comparison to the amount of oils. Too little can cause the oils in the soap to go rancid and smell bad. When you find a good recipe for soap making, make sure you stick with it.


Soap Making

Fats and oils, by themselves, do not mix with water. Sodium hydroxide breaks up the triglyceride in fats and oils and turns the fatty acids into sodium salts. The salts reduce the surface tension in liquids and allow grease to be easily washed away with water. Try making a pure soap with no perfume, fragrances, dyes or additives that can irritate your skin. Using a pure soap with only the glycerin can cleanse and improve your skin condition – no matter what that condition is. Pure lye soap will sooth insect bites and actually repel insects with its residue. Try shaving your lye soap and using it as a laundry detergent, or rub a bar directly on a problem stain. Lye soap has been found to be as effective as commercial products on the market.

Usefully Destructive

Harnessing the power of caustic soda can be very useful to the resourceful individual. The same properties that convert oil and fats into soap can be put to use in dissolving the grease and hair that slows down (or completely clogs a drain). Put a heaping tablespoon on a slow running drain and slowly poor in just enough water to dissolve. Remember to allow for adequate ventilation, let sit for 10 minutes, and then flush with hot water for a couple of minutes to clear the pipes.

Mix one (1) cup of lye, one (1) cup of cornstarch and two (2) gallons of water to make an effective paint stripper. Try some experimentation to give painted items a rustic or distressed look.

Make traditional soft pretzels by bathing them in one (1) quart of water with one (1) ounce of sodium hydroxide mixed in for thirty seconds. Your finished product will be a dark brown, soft and delicious. The finest bagels are similarly boiled in a lye solution making them soft and chewy. Many recipes attempt to substitute sodium hydroxide with baking soda, but reviewers agree that the ‘lye bath’ produces much finer results.


Pure Lye

Make sure you know what you are putting in, and on, your body. While commonly stocked in hardware stores as drain cleaner, it can also be mixed with other chemicals you don’t necessarily want in your food or soap. Don’t trust a product, intended only to clean drains, to make something you plan on putting in or on your body. Our product is 100% pure and you can be confident that you are using only the finest ingredients.

  1. No Lie, its good lye!

    Posted by Gary Mullins on 4th Dec 2015

    Performed as good as anticipated in hot process soap. Will order again soon.

  2. Best!

    Posted by Unknown on 1st Dec 2015

    This lye is awesome. Ordered 8lbs and it was shipped super quickly and the shipping was also affordable. I don't like sounding super frugal, but for soapers it can be difficult to find lye at a good price and quantity that isn't an arm and a leg to ship. I will be ordering from here from now on for my lye.

    The only downside is because it's not flake form, it is kind of static and can kind of spread into the air and onto your counter, so make sure you use gloves and protect your face! Even though I love this lye, I would be so happy to see flake form eventually. Thanks BA!

  3. very good lye

    This micro bead lye always arrives in good condition, rarely is it clumped, and is packaged in 4 bottles diminishing the chance for future clumping.

  4. Great for soaps

    Posted by Angel on 20th Nov 2015

    I make both cold process and hot process soaps and this lye works well in all recipes. I enjoy that it is packaged in smaller containers which makes handling easier and safer.

  5. Lye beads

    I have been afraid to purchase lye beads because people have said they fly around. This lye product were more like timy beads or granules. They did not fly around and did great with my batch. Loved the price compared to other places and perfectly fine quality so gar!

    Got my shipment of lye yesterday and it works great! It does have a bit of static and jumps around when your pour but if your aware of it before you start you just have to be careful to pour in a safe area. The soap I made is beautiful though!
