To harden it into bars she said they added table salt after it all came together. 2. Potassium hydroxide derived Castile soaps are more easily dissolved and diluted in water and are hence favored for liquid soap production for this reason. When sodium hydroxide is used, a hard soap is produced. In addition to being softer, this type of soap has a lower melting point. Oils are an extremely important component of the soap making process, and without oil (or fatty acids of oils) the saponification reaction can’t take place.

There are two main types of lye used in soap making: sodium hydroxide and potassium hydroxide. (I use Essential Depot or Bramble Berry with good results.) Soap scum is created by the reaction that occurs when soap is combined with metal contaminants in hard water like calcium and magnesium. Hard soaps are especially good cleansers in hard water that contains magnesium, chloride, and calcium ions. In the example above the cocoa butters sodium hydroxide SAP value is 138. With black soap the water is seared out of it in the final stage and the soap is dried overnight. Read more about potassium hydroxide here. If we were going to use ten ounces of cocoa butter. Soap Test. With bar soaps, the chemical reaction takes place with sodium hydroxide. Saponification is the reaction from mixing these oils with an alkaline base - commonly this is Sodium Hydroxide (NaOH) or Potassium Hydroxide (KOH). Potassium hydroxide (KOH) - KOH is the caustic substance used to turn skin-loving oils and butters into soap. So you could take 6.13 oz needed – 3.97 already used = 2.16 ounces that you could dilute with 3x as much water and stir into the batch while rebatching in a crockpot. Most soap these days is made from Sodium Hydroxide, it is cheaper and makes a harder soap. The chemical reaction of making soap, called saponification, is complete, the lye and oil molecules have combined and chemically changed into soap and glycerin. I do not know for sure, but Ca(OH)2 is a much weaker base than sodium or potassium and will probably be unable to hydrolyze the fatty acids. Projects To Try. Experiment 718: Making Soap - Saponification . We would multiply the ten ounces of cocoa butter by .138. Soft Soap: Soft soap is made using potassium hydroxide (KOH) rather than sodium hydroxide.

For liquid or very soft soap potassium hydroxide is normally used and for a hard bar sodium hydroxide is used. Do not breathe over the bowl and stand away as you stir. While potassium hydroxide tends to yield soft, highly soluble soaps, sodium hydroxide produces the opposite, and has long been used to make ordinary bar soap. Many of us must have studied that in this process of saponification; if the sodium hydroxide is used then the hard soap will be produced and potassium hydroxide will produce the soft one. The biggest difference between this soap and other conventional cold or hot process soaps is that we are going to be using both sodium hydroxide (lye) and potassium hydroxide (KOH). Potash soap This soap is more grainy and crumbly. One of the most common was to make soap was with ashes from a fire that were boiled. Also known as KOH or Caustic Potash, it is a colorless white solid commonly found in flake, pellet or powder form.Like sodium hydroxide, potassium hydroxide is an essential ingredient in soap making as you can’t make soap without lye. Saponification Chart for Soap Making. The potassium soap is one of those products that we can use for plants to stay in perfect health condition. You see, lye (sodium hydroxide) is formed when wood ash (which is mostly potassium carbonate) is mixed with water. The resulting soap will be softer and dissolve more readily in water than a corresponding NaOH soap, though. Elaine White, the American Soapmaker, is responsible for the following chart. Sodium Hydroxide makes a hard soap and potassium hydroxide makes liquid soap. Soap: A compound made of natural fats, oils, or butters and a strong alkali such as sodium hydroxide (also called caustic soda), or potassium hydroxide (also called caustic potash). Cream soap is a hybrid of the two, made using both sodium hydroxide and potassium hydroxide, together, to make soap staying at cream consistency. When you add the potassium hydroxide it will sound like it is going to explode or boil over, but the water does not bubble up at all and it doesnât even heat us as much as sodium hydroxide so donât worry. and you should be wearing goggles and gloves). Now lets look at the chemical used in each of the variations. Stir the mixture continuously until it thickens. Never leave lye exposed to open air; replace the lid when not in use. In Soap Making: When potassium hydroxide flakes are mixed with a liquid, a basic solution is created. Postassium hydroxide the lye used to make liquid soap is much more preferable than using sodium hydroxide for bar soaps, there are a lot of shaving soap that use potassium hydroxide only and some use a dual lye usually 60% to 70% potassium hydroxide and 40 to 30% sodium hydroxide. Potassium Hydroxide Lye Flakes ( KOH) Potassium hydroxide is lye for soft and liquid soap making. Because more soapmakers use lye (sodium hydroxide), good soap calculators allow you to choose NaOH (lye) or KOH (potassium hydroxide). You can source this from your local soap store or, pick up from Essential Depot on Amazon. Liquid soap uses potassium hydroxide. Soap made with ammonium hydroxide (NH4OH) solution is slightly more water soluble than soap made with potassium hydroxide. Using infused oil: prepare your infused oil (ie. They are prepared by reacting fats and oils with a strong base, such as sodium hydroxide or potassium hydroxide.
