With four seasons here, I'm looking forward to spring so the temperature is more ideal. Additives I turn my oven off and put my soap inside the warm oven and leave it over night. As you continue to rub the bar against your skin or washcloth, the abrasion removes soap molecules from the soap crystals as well as from the liquid phase. Each kind of soap molecule has different chemical properties. It makes a moisturizing yet cleansing bar with tons of lather. There are tons of different methods for making soap and over the years I have decided that this way works best for me because it’s quick, easy and I don’t need to measure any temperatures. I love the process of making soap, but what I love even more is developing recipes for it. Basically, CPOP is forcing a hot, extended gel phase with the help of an oven. But there is a method called hot-process soap making that speeds up the time it takes the soap to cure. Test the quality of the lather, longevity, and hardness of the bar and mildness to the skin over at least 3 months, preferably longer. Some soap makers allow for this by curing CP soap a minimum of 4 weeks and HP soap a minimum of 6 weeks. When a bar of soap is newly made, the soap crystals contain a jumbled mixture of myristic, lauric, palmitic, and stearic soaps with a fair number of oleic soap molecules squeezed into the crystals for good measure. The soap is then pressed or extruded into finished bars. Place your soaps in an out-of-the-way place to cure. I want to stress this point -- Even though we tend to think of a bar of soap as a dry solid, it's actually a unique mixture of solid particles and liquids. Unless I need the oven for something, I leave the soap in the oven for a couple more hours to start cooling down. Cold processed soaps need time to cure and age before they can be labeled and soap. Generally speaking, this takes three to six weeks, but there are some cases when it can take even longer. The third aspect of curing soap is developing soap's crystalline structure. Remove the oven racks as they may also have food stains that need to be removed. Not sure what process is right for you? The oven’s heat will evaporate more liquid out of the soap. But neither of these soaps will be at their best if used so young -- they will not lather as much, be as physically hard, or last as long as they will after a full cure. Step Eleven: Perform a Ph test for safety. We all desire a hard bar of soap. All rights reserved. Every oil brings its own properties to a bar of soap, and finding the perfect soap recipe is a balance of those things. The fatty acids usually come from fats. The cure time is all about water evaporation. It lathered very poorly at 2 weeks and only a little bit better at 5-6 weeks. When your soap is done with the 4-6 week curing time (or whatever the batch needs), put the bars into a plastic bin. I've been making only HP soap b/c of the quick turnaround - it works better for my space situation. Putting your soap in the oven, even at a low temperature, will just cause melting and gooey soap. Pour soap into plastic lined mold. At this time, most people say the soap is ready for use or for sale. Since HP soap is usually made with more water than CP soap, the drying time for HP soaps actually takes more time, not less, before the soap stabilizes at a reasonably constant weight. Lay out the slices on the rack so that they have at least 5 cm (2.0 in) of space on all sides. They can form many different shapes -- plates, irregular blocks, or even long spears. After one hour, turn off the oven and leave the pan in the oven to cool completely. But is the cure truly done at this point? After 12-24 hours your soap will be ready to unmold. (This applies to hot process soap too.) If small amounts of rust persist, use a scouring pad or bristle brush to gently scrub. If decorating top of soap, spritz with water and sprinkle on herbs, … Stearic and palmitic soaps salt-out quickly and well so they become concentrated in the solid soap crystals. Heat your oven to 170-180°f, then turn it … I turn my oven off and put my soap inside the warm oven and leave it over night. Allow to sit for another day or two, unmold and cut. Fill warm water in a large tub or sink, add a few drops of eco-friendly liquid dish soap to it. When you begin to wash with a young bar of soap, it is often the case that the soap will not lather well at first. from North Country Soap Making Library. When you wash with a bar of soap, the wash water penetrates the surface of the bar and mixes with the liquid phase. The soap is called CPOP and may have less water and less curing time, but curing time will vary based on the recipe and other factors too. The oven folds to the size of a stadium cushion and weighs in at 1.2 pounds. After soap is in the mold, the process of saponification can cause the soap to heat up. Copyright © 2002-2020 - All rights reserved by Classic Bells Ltd. of curing soap is developing soap's crystalline structure. The concentration of stearic and palmitic soaps in the solid crystals begins when enough water evaporates to trigger the salting-out process. So how does this relate to how soap changes during cure? Putting your soap in the oven, even at a low temperature, will just cause melting and gooey soap. Only water evaporation will accomplish that task, so it is a necessary beginning to the curing process. Place your soaps on the shelf. This difference between the liquid and solid phases affects how the soap performs at the sink or in the bath. is oven-dry and all water has been removed. Anyone who has eagerly bathed with a freshly cut bar of soap and gotten some skin irritation has learned that lesson. Initial weight - Oven - dry weight MC - x 100% (2) Oven - dry weight I added a very small fridge on the floor and all my oils sit on it so I still manage to keep the counter relatively clear for soaping and a rarely used room is used all the time now. There’s also a process called ‘Oven-processing’ where you cook your cold process soap in the oven at a relatively low heat for up to an hour. The soap will be thick and not easy to manipulate into mold. Let's get iNaturalBody! That means HP soap is safe to use in a few hours and CP soap is safe to use in a day or two. I’ve used it quite a lot. Since HP soap is usually made with more water than CP soap, the drying time for HP soaps actually takes more time, not less, before the soap stabilizes at a reasonably constant weight. The glycerin and other dissolved chemicals must be concentrated enough so soap molecules start to salt-out. Salting-out is the process by which soap molecules coalesce from a liquid form into solid soap crystals. And it is true that CP soap takes longer; a typical CP soap might need 1-2 days to finish saponifying. Homemade Soap: You Don't Have to Wait for a Month for This Soap to Cure. (To learn more about salting out, read my article about cleaning soap scraps.). What could be causing this gradual improvement, even after water evaporation has slowed to a crawl? Using the oven. Check out our article on Hot Process Soap Versus Cold Process Soap. Try a long-term experiment with a few bars of your favorite freshly-made soap. Remember from the CPOP post that according to Professor … At the end of this time, see what your test results show. It involves placing the molded soap into the oven at about 150-170 degrees until the soap fully gels. Zeolites. This bulky shape prevents oleic soap molecules from fitting nicely into the structure of a soap crystal, so the liquid phase in a bar of contains many more oleic soap molecules than what you might think from looking at the soap recipe. The sodium comes from sodium hydroxide, NaOH. Measure the water loss during this time. Repeated tests of lathering, hardness, longevity, and mildness have proven this point to me. Many soap makers let castile soap cure for six to eight months. This method of using hot process calls for heat being applied while the soap spends time in the oven. It will usually take 3 or 4 weeks for soap to cure. Soap molecules based on these fatty acids pack tidily into a soap crystal. This soap had definitely improved over the months. Palmitic acid is medium length and the soap it makes is moderately soluble in water. These soap molecules also gradually trade places with lauric, myristic, and oleic soaps in existing crystals. After the soap is poured into your mold, place it in the oven. The soap molecules in the liquid phase can be distinctly different than the soap molecules in the crystals. (This applies to hot process soap too.) The liquid in a bar of soap is just as important to the overall performance of the soap as are the crystals of solid soap. I agree the extra-long cure time needed to turn this mostly-lard soap from a duckling into a swan is an unusual case, but I think it shows that curing soap is more than simple water evaporation. This is the lowest my oven will go, if yours goes lower, you can start at its lowest setting. The first aspect of cure is to complete the last lingering bits of saponification to ensure the soap is safe to use on the skin. As more soap molecules accumulate on your skin or washcloth, they will build a larger amount of lather. My first real-life experience with the benefits of a longer cure was a soap made with 90% lard. I was so unimpressed with this soap after using a few bars that I put the rest in a dark corner of my soap cupboard and ignored them. Last but not least is oleic soap. Use this paste to cover the stains. Some soap makers allow for this by curing CP soap a minimum of 4 weeks and HP soap a minimum of 6 weeks. This site uses Akismet to reduce spam.

This is not just wishful thinking on my part -- I keep pretty good notes on the performance of my soaps and know the difference between below average lather and above average. This cold process soap recipe is the best ever. This cold process soap recipe is the best ever. Instead, stir mixture with a wire whisk until opaque and place in a 225 degree preheated oven. A bar of soap is a complex mixture of solid crystals entirely surrounded by a film of liquid. After one hour, turn the oven off, leaving the soap to sit overnight. Once the gel stage starts, it will start in the center of your mold and work its way outwards towards the edges. I discarded my oven rack for curing and now I use the rack in the closet for curing soaps (a wire rack: perfect). If you create a graph that tracks these weights with time, you will most likely see a trend something like the chart below. When you are finished creating your cold process soap and have it safely in the mold, you can put it in a warm oven to force the gel stage. When your soap is done with the 4-6 week curing time (or whatever the batch needs), put the bars into a plastic bin. After 4-8 weeks has gone by, the rate of water loss from a bar of soap will slow to a crawl (see the chart above.) Dry the skillet thoroughly, and then follow the above curing technique, repeating at least 3 to 5 times. First things first. However, if the soap is too high of Ph, you may have used too much lye. One of the main benefits of this is being able to unmold your soap faster. Homemade soap usually needs to cure for a month before you can use it—longer if you want a nice hard bar of soap that will last. Be sure to read this exceptionally informative article on Curing Soap from the Classic Bells website. Layering paper towels. It is true the HP "cook" causes the soap to fully saponify within a few hours. Commercial soap makers quickly dry their freshly made soap to the desired water content, and then mix the dried soap chips or noodles under pressure using a machine called a "plodder." Oleic soap molecules will predominate in the liquid phase due to their bulky shape, but there will be a fair number of all the other soap molecules in the liquid, including nearly insoluble stearic and moderately soluble palmitic soaps. At this point, I want to debunk the myth that hot process soap is 100% ready to sell right after it is made while CP soap takes weeks to get to that point. Stearic acid, the longest fatty acid, makes soap that is almost insoluble in water. The effect was kind of cool, but it ruined the soap. The soap should be slightly alkaline. Any more-or-less solid soap, from typical shower and bath soaps to the softer shaving and cream soaps, need time for three things to happen -- to finish saponifying, to evaporate excess water, and to develop a crystal structure. Not every kind of soap molecule will salt-out to the same degree. Curing = drying. Drop the filled mold onto table and run a knife through it to remove air pockets; Cover with plastic wrap; Cover with towels; Allow to cool for 6 - 24 hours; Cut into bars. I know it’s hard for me to wait too! Scoop soap mixture into prepared mold. … Every oil brings its own properties to a bar of soap, and finding the perfect soap recipe is a balance of those things. After twenty minutes, take mixture out of the oven and stir with wire whisk. Want to see some behind the scenes? There are a few reasons why this step is necessary. Many soapmakers use a process called cold processes oven process (CPOP) to force their soap to gel in the oven. TEN: Pull the soap out of the oven. Curing cp soap in garage by: Anonymous I'm a new soaper and I live in Connecticut. Soap is made from three basic ingredients: Fats (oils), Lye (use to turn the oil into soap), and Liquid (used to dissolve the lye, and add other properties to the soap). Spacing the slices out on a wire rack improves the air flow and decreases the drying time. It is very important not to sell fresh soap. All cold process soap recipes can be oven processed. Put the lid on your dutch It makes a moisturizing yet cleansing bar with tons of lather. The glycerin and other water soluble chemicals will be more concentrated as the water content drops. Using the oven. Over time, the excess liquid in the soap evaporates, the bar hardens and becomes milder. Dilution can modify harshness -- more water in the diluted soap will reduce the cleansing action. The high concentration of glycerin and other water-soluble chemicals in an older bar of handcrafted soap has an unexpected effect. I tried a bar at the sink first and found it lathered dramatically better at 1 year than it did earlier. Harden the Soap . Ingredients Needed: 13.5oz Distilled Water 9oz Sodium Hydroxide 40.6 oz Olive Oil (pomace grade or extra virgin will both work.) It is very important not to sell fresh soap.

Check it regularly to make sure it is not feeling sticky or damp – if it does, it needs to sit out and cure longer. When a batch of soap is made from fat, the soap molecules within the soap will vary in size and shape, depending on the different fatty acids present. If the cure was only about water evaporation, we should see little or no change in these soap qualities. Handcrafted soap may be SAFE to use shortly after it is made, but it will not be at its BEST until some weeks or even months go by. Technically the method I show in this video would probably be called Room Temperature/Oven … Basically, CPOP is forcing a hot, extended gel phase with the help of an oven. An oleic soap molecule is the same overall length as stearic soap, but it contains a double carbon bond that twists the oleic soap molecule into a "U" shape. Learn how your comment data is processed. the internal temperature of the soap with a thermometer and turn the oven off when the soap temp reaches between 180-190 degrees. Keep good written notes as you go -- do not count on your memory to be accurate. When making cold process, oven processed soap, you make soap the cold process way. The obvious and main pro is that unlike traditional cold process soap, it does not require a 6 week cure time. Castile soaps or any other soap made with high amounts of olive oil benefit from an even longer cure. Water is necessary to make soap but the extra water in the soap is not needed. Using a baking sheet may increase the drying time by up to double. Answer: The method you are referring to is called the Cold Process Oven Process soap method. Curing soap means that the soap is left to age, mature, and well… dry out. The second aspect of curing soap is the loss of water. I love the process of making soap, but what I love even more is developing recipes for it. The trick to this process is using an oven safe mold, and really getting to know your oven. Be sure you are using heatproof molds, like silicone. The effect was kind of cool, but it ruined the soap. CPOP stands for cold process/oven process. Curing Soap. These molecules from the crystals mix with the soap molecules from the liquid phase. Now is a good time to send them to us. 3. Remove the oven rack from the preheating oven, or use an oven-safe wire rack. Any soap, whether HP or CP, will be at its best only after completing the other two aspects of cure -- the loss of excess moisture and development of crystalline structure. Be sure to read this exceptionally informative article on Curing Soap from the Classic Bells website. The most common fatty acids for soapmaking, from the smallest in size to the largest, are lauric, myristic, palmitic, stearic, and oleic. https://www.rachaelraymag.com/recipe/how-to-dry-citrus-in-the-oven During the cure time water dissolves from your soap creating a harder and longer-lasting bar in your shower.

I walk your through the entire process and what to look for in the video below. Try it for yourself, if you have not already, and see what you think. I lay mine up on their side so that more surface area has air exposure. This shift in the kinds of soap molecules in the liquid phase usually creates a faster building, more abundant lather for a smaller amount of work. So why does soap need to cure anyway? You will want to keep a close eye on it to ensure it does not over heat. View Our Disclosure Here. When it's time to cook with your shiny new skillet, make sure to wash it with hot water (no soap this time) and dry it completely after each use. Fatty acids with a simple straight shape are lauric, myristic, palmitic, and stearic. When you unmold a soap, the saponification might be 99% done, but it's a very wise idea to wait for that last 1%. A harder bar will last longer allowing you to enjoy it longer. In my experience, however, soap made with a more balanced blend of fats should perform decently well after a 4-8 week cure, with a more gradual improvement after that time. The amount of lather usually increases as you keep rubbing the bar, because you are scrubbing more soap molecules off the soap crystals. Gel phase is temperature phase. I know it’s hard for me to wait too! But, giving soap a full 4 to 6 weeks cure time, at minimum, is important. I know of no easy shortcuts -- handcrafted soap needs at least 4-8 weeks of cure to perform well and some will benefit from even more time. Evaporation causes a bar of soap to lose weight, shrink somewhat in size, increase in hardness, and become less soluble in water. This is a process that most people can't see or measure, so they tend to ignore or discount this as not being important. Additives The crystals are made of soap molecules fastened together in various 3-dimensional arrangements. I’ve used it quite a lot. There is a similar liquid inside the crystals as well, but for the purpose of this discussion, the liquid in the crystals is not as important as the liquid surrounding the crystals. I'd like to make CP which I want to cure in my garage (much more space). I turn my oven on to warm (your want it to be about 170-180 degrees F. I made my soap as usual. Set timer for 60 minutes. Myristic and lauric and oleic soaps do not salt-out nearly as easily, so they remain in the liquid phase. Thanks for tuning in today. Any given fat is a blend of several kinds of fatty acids. As the glycerin and other dissolved chemicals in the liquid phase become sufficiently concentrated, the stearic and palmitic soaps in the liquid phase will form solid soap crystals -- in other words, they want to salt-out. But the migration of insoluble soaps into the crystals and the transfer of more-soluble soaps into the liquid phase is not a fast process. You can always buy it in our Etsy shop! At 4-8 weeks, it is true that most soap lathers better, lasts longer, and is milder to the skin, but soap often performs better as even more time goes on. The more important reason to cure your soap is for the water to slowly evaporate over time, which causes the soap to harden. During the cure time water dissolves from your soap creating a harder and longer-lasting bar in your shower. Layering paper towels. Check out our YouTube channel! This applies to soap made with hot process (HP) methods as well as cold process (CP) methods, despite much advice to the contrary.

What are the individual soap molecules like? I let mine sit for 5-10 minutes and watch closely for the gel stage. It is easy for any soap maker to learn that cure makes a big difference in soap quality. About a year later, I was tidying one day and decided to toss the last of the bars from this recipe. A "cure" time for liquid soap is mainly to allow time for the last bits of saponification to finish and allow any particles that might be in the soap to sequester (settle out).

I have to say, once you start soaping, it is hard to stop. As time goes on, the crystals in a bar of soap will contain more and more of the less-soluble stearic and palmitic soaps and the liquid phase will contain more of the soluble lauric, myristic, and oleic soaps. Steps To Use Dish Soap To Clean Oven #1. Each has its own benefits, but when you combine the processes, you reap the benefits from both. Once that starts to happen, I turn my oven off and let to soap sit in the oven until the gel reaches the edges. After soap is in the mold, the process of saponification can cause the soap to heat up. A few days should be long enough for a properly made soap to finish saponifying. In a hand-made superfatted soap, the film of liquid surrounding the crystals is a complex alkaline mixture of water, glycerin, and other water soluble chemicals as well as an assortment of dissolved soap molecules. Paper will burn at 451ºF/233ºC, so there is no danger of paper towels getting hot enough to burn at the drying temperature. NINE: Stick the soap into an oven, preheated to 170 degrees Fahrenheit, and set the timer for 1 hour. There are two main ways to make soap, cold process and hot process. Are there other ways to force this shift in the crystal structure and the liquid phase? And that, in not a nutshell, is why curing soap is a complex process that goes beyond water evaporation. In summary, the hot process method only speeds saponification; HP does not shortcut the rest of the cure time. This is what Cold Process Oven Process Soap is, a hybrid of both processes. A single soap molecule in a bar of soap is a fatty acid ion usually combined with a sodium ion. Even though you can use cold process, oven process soap right away, I would always recommend letting it cure for a few weeks so that you get a nice hard bar. You will want to keep a close eye on it to ensure it does not over heat. When the pan is cool, wipe away any excess oil with a paper towel. 3. For the purpose of this discussion, I want to share that lauric and myristic acids are the smallest fatty acids, and the soap they make is highly soluble in water. Yes, if you have the equipment. [adsense_hint]. Copyright © 2018 Three Little Goats. I tried it at the end of the cure time once and my soap cracked all over the surface, kind of like crazing on old china. This method will speed up the time the soap gels at but I'm not so sure if it actually speeds up the cure time. I let mine sit for 5-10 minutes and watch closely for the gel stage. But once sufficient evaporation happens, the slower process of restructuring the soap then begins. While I am making my soap batter I preheat my oven to 170 degrees Fahrenheit. Since the process is not well understood by handcrafted soap makers, I want to talk about this in more detail. Hot Process Soap Versus Cold Process Soap, How to Make Lotion Sticks & Homemade Lip Balm, https://www.youtube.com/watch?v=_FpufPu-5yk, https://www.youtube.com/watch?v=991_GNVPVA4&t=738s, https://www.youtube.com/watch?v=uuSLJkVcyVs.

Depending on the space you have to work with, you can use a bookshelf, utility shelf, bakers rack, or whatever you have that will fit your space. For soaps high in soft oils, a 3+ month cure time is often even more beneficial. For handcrafted soap makers, the most practical solution is to allow time to solve the problem -- time to finish saponifying, to evaporate water, and to develop the crystal structure. The liquid phase surrounding these young crystals is large, and it also contains a jumbled mixture of soap molecules. Soap orders by soap by the loaf are cold processed soaps. A harder bar of soap will last longer, produce more lather, and just be an overall better bar of soap. High oleic soaps (olive oil soap for example) also need a longer cure time for best performance. Since the process is not well understood by handcrafted soap makers, I want to talk about this in more detail. Crystals can be big or small, long or chunky. I turn my oven on to warm (your want it to be about 170-180 degrees F. I made my soap as usual. The larger amount of less-soluble soap in the soap crystals has the benefit of making the soap more resistant to wearing away from use. Homemade Soap - Curing the Soap Quickly. In this video, I am sharing with you tips and tricks to decreasing curing time on cold processed soaps. The water content in the soap might be 50% to 70% of the water originally in the soap bars when they were cut. Cold Process Oven Process (CPOP) is one of the best ways to force your soap to gel.

Here is how I do it. The reason for the poor lather is the larger amount of less soluble and less bubbly stearic and palmitic soap molecules in the liquid phase in proportion to the more soluble myristic, lauric, and oleic soaps. Here is how I do it. If you were to step into your shower with a brand new bar of soap it would dissolve pretty quickly. Step Ten: Unmold and cut your soap. Soap does not have to come to trace.
