    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. Sodium Hydroxide (Lye) 5 star review

      Posted by on

      I needed this product to make some soap. I searched the internet and found this to be the best price. It was a great deal to get 8lbs. for so little. Fast shipping and packaged well. Will be ordering again.

    2. lye for soap making 5 star review

      Posted by on

      Works great for making my soaps always fresh and packed well. Arrives fast.

    3. Great value. Better than the flakes 5 star review

      Posted by on

      No issues at all with clumping or non dissolving. Great value. Would not buy from anywhere else.

    4. Great Price For A Great Product 5 star review

      Posted by on

      This lye is super quality and I can not lie ;). It is about 1/3 of the price of lye at the local hardware store. It is a little static but it is well worth the extra cleanup.

    5. Works as it should 5 star review

      Posted by on

      I have made dozens of batches of soap using this lye. Yes, it can get a little static in the cup, but I'm extremely careful when using it, and I have not had it "go flying everywhere" in my experiences with it. I did try someone else's tip of a dryer sheet rub in the cup first and that did not work for me unfortunately.
      Regardless it's extremely reasonable in price, it works exactly as it should, shipping is pretty quick and I will continue to use this for all of my soapmaking needs in the future.

    6. So far so good. 4 star review

      Posted by on

      So far I'm happy with the lye. In my experience no lye is perfect. The soaps I've made with this lye have not fully cured, so I don't have a definitive opinion, but I'm expecting it to be fine. My only real complaint is that the lye reassembled itself into a rather large flake when I was dissolving it in frozen milk. That was probably more my fault than that of the lye. You can get in too big of a hurry sometimes with that process. I have a really good mask to help keep dust out of my lungs. Every lye I've used has had dust, so nothing out of the ordinary there.

    7. Would prefer Lye flakes 4 star review

      Posted by on

      Lye is Lye but I would prefer lye flakes instead of beads. I find when using this product, static pulls the beeads and they go flying everywhere when scooping or pouring it out. Make more for clean up as you don't know where all the little beads flew to

    8. Best Prices; Excellent Service 5 star review

      Posted by on

      I make cold process soap and love buying my lye from this company. They have the best prices and they have a quick delivery. It is always packaged well.

    9. Only lye I will buy. 5 star review

      Posted by on

      Perfect sized bottles, easy to pour, never clumps, and the quality is always top notch.

    10. Excellent, just a few things to know.... 5 star review

      Posted by on

      I have used this before and was very worried that it wasn't behaving well - thought it was contaminated or that my soap would not turn out. However, I discovered through testing that it doesn't get as hot as I am used to (210F), more like 190-200F, but it works just fine in soaping.
      The crystals can get everywhere (I live in a very dry climate), which can be dangerous, however I rub my container with a new dryer sheet before measuring the lye in it, which prevents static and lye crystals from flying around.
      I would recommend this product - it is a good price and comes well packaged. (The bottles are very thick and work well for other things after a good cleaning.)
