One special thing to remember Superfatting is the process of adding extra fats oils or butters when formulating a natural soap recipe, so there is more fat in the mixture than the lye can react with during the chemical reaction.
We use a lot of extra fats oils or butters when formulating a natural soap recipe. Superfatted soaps have superior moisturizing and emollient qualities.
If you look at the colored picture of the chemical reaction above, in addition to "soap," glycerin, and water, Chagrin Valley Soaps also contain free oils that have been left unchanged by the saponification process and add extra moisturizing properties to our soaps and shampoos!

But when they come together in a chemical reaction a totally different substance is created -- table salt NaCl! There is no explosive sodium and no deadly poisonous chloride gas left at the end! Lye has many uses in the food industry. The secret to great pretzels is often a lye bath!
Lye gives pretzels their characteristic flavor, crispiness, and glossy finish. Hominy is dried corn kernels reconstituted by soaking them in lye water until the germ is removed. Lye may also be used in the preparation of olives and pickles. Skip nav to content.
February 18, Won't It Harm My Skin? Acids are at the lower of the spectrum, while bases, also known as alkaline substances, are at the higher end. Both strong acids and strong bases are caustic and can damage human skin, which is why lye has a reputation for being dangerous. If lye comes in contact with your skin, it begins to react with surface oils—a painful prospect! However, that only applies to liquid lye, the pure chemical solution.
What is lye used for? This chemical is essential to a variety of industrial purposes, the most famous of which is making homemade soap. Others include:. Back in the day, our ancestors made old fashioned lye soap by boiling wood ash. Then, lye was skimmed off the top. In addition, some ancient soap makers made an alkali from sodium bicarbonate baking soda and calcium oxide. Both of these methods yielded inconsistent lye that made it more difficult to measure its potency and accurately calculate the amount of fat that had to be added to make safe soap.
Salt NaCl is dissolved into water. Salt crystals fall to the bottom of the container. Electricity is then run through the rods. Attracted by the charge, crystals of lye attach themselves to the rods. After that, the liquid is poured off and allowed to evaporate until nothing but lye crystals remain. Then, this lye can be used for a variety of purposes, including making soap batter.
What is lye soap? The short answer is that all soap is lye soap. True soap bars cannot exist without lye. Bar soap is made through a chemical process known as saponification sapo is Latin for soap :. A lye solution is combined with oil or fat to cause a chemical reaction. This reaction breaks down the fats or oils into fatty acid chains and the lye mixture is neutralized in the process.
Lye can react with oils and fats in a heated environment or a cold environment. Through a hot process method, soaps can go from liquid form to a solid bar form in minutes. When an outside source of heat is applied to a lye and oil solution, the water molecules in the oil evaporate and the saponification process is sped up. Although hot processing lye is much quicker, we chose to cold-process our bar soaps.
Heat can change the chemical characteristics of essential oils and we want to deliver their best, most potent effects in our natural soap. One of our favorite natural bar soaps is Fighting Five , which is packed with immune-boosting properties to help eliminate germs without drying out your skin. Without lye in soap making, there would only be puddles of fat and oil. In fact, if a soap bar is not made primarily of cleansing alkalized oils, the FDA does not consider it a soap at all!
What is soap without lye? Fill the barrel with the wood ash, placing it on top of the straw, to within 4 inches of the top of the barrel. Slowly pour the collected rainwater over the ash so that the ash is wet but not soaking. It is easiest to fill buckets with the rainwater first, and then pour each bucket into the wooden barrel. Once the ashes begin to float and you can see the waterline, stop filling the barrel.
Note how many buckets of rainwater you add so you know how much lye water will be produced. You will need enough lye-safe buckets to match the amount of water you add to the barrel. You do not need to place a lid on top of the barrel unless it has been placed in an unprotected, open area. Before you can collect the lye water, you need to put on the safety equipment.
Wear elbow-length plastic gloves, safety goggles, and boots when handling the lye water. It is time to collect the lye water when it is within 4 inches of the top of the bucket. Carefully remove the full bucket, being sure not to spill, and replace that bucket with another lye-safe bucket.
Before you can use the lye to make soap, you need to make sure it is the right pH. To do this, you will need either pH test strips or a pH meter. If you have neither, you can use a potato—if it floats, the lye is ready; if it sinks it is not. The pH of each bucket of lye water needs to be 13 or more. If it is below 13, carefully pour the bucket of lye water back into the wooden barrel and collect it again.
Repeat this process until your buckets of lye water are at a pH of It will most likely take at least one more run through the barrel to reach the right pH level. Take care not to splash when pouring the liquid back into the barrel as the water can burn your skin. Once you have the lye at a pH of 13, you are ready to use it as you wish. You can use the lye water to make soap, unclog drains, or cure olives.
