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.

    Thank heavens for Bulk Apothacary. Just got back into soapmaking, and was thrilled to find your company. I am only an hour and a half away from you, so technically I could pick up my supplies. But when I calculated shipping, it was cheaper than driving. The lye was perfect and packed nicely.

    Posted by Char L on 17th Jul 2015

    The only reason I gaved this product a 4 star is the packaging. It comes in a large bucket and the beads " fly away " on my floors when I open the bucket. Wish they would make it in 4 lb or 2 lb container. Otherwise this is a great product. Soaps comes out perfect every time.

  6. Absolutely the best

    Posted by Laura on 16th Jul 2015

    I make and sell soaps amount other things. This lye seems to give me the best results and it is offered at the desk price I've found. The individual containers are secure to prevent moisture and spills, but easy to open and handle. For anyone needling lye this is a top choice.
