This is true even though the young soap is relatively soft and contains a fairly large amount of water. Prepare the mold by greasing the bottom and sides with olive oil. Only water evaporation will accomplish that task, so it is a necessary beginning to the curing process. In this video, I am sharing with you tips and tricks to decreasing curing time on cold processed soaps. At the end of this time, see what your test results show.

Place your soaps on the shelf. I've been making only HP soap b/c of the quick turnaround - it works better for my space situation. Ingredients Needed: 13.5oz Distilled Water 9oz Sodium Hydroxide 40.6 oz Olive Oil (pomace grade or extra virgin will both work.) And that, in not a nutshell, is why curing soap is a complex process that goes beyond water evaporation. Check it regularly to make sure it is not feeling sticky or damp – if it does, it needs to sit out and cure longer. The crystals are made of soap molecules fastened together in various 3-dimensional arrangements. If I need the oven, then I just pull it out and set it on a counter to cool for 24 hours. Since the process is not well understood by handcrafted soap makers, I want to talk about this in more detail. If you create a graph that tracks these weights with time, you will most likely see a trend something like the chart below. The cure time is all about water evaporation. Curing Soap. But is the cure truly done at this point? 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. CPOP stands for cold process/oven process. I’ve used it quite a lot. Layers of paper towels in between soaps only make the moisture problem worse. 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. The amount of lather usually increases as you keep rubbing the bar, because you are scrubbing more soap molecules off the soap crystals. Be sure to read this exceptionally informative article on Curing Soap from the Classic Bells website. 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. NINE: Stick the soap into an oven, preheated to 170 degrees Fahrenheit, and set the timer for 1 hour. I tried a bar at the sink first and found it lathered dramatically better at 1 year than it did earlier. 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. 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 Sunflair Solar will float if it were to fall into water. The soap is then pressed or extruded into finished bars. So how does this relate to how soap changes during cure? After one hour, turn off the oven and leave the pan in the oven to cool completely.

I lay mine up on their side so that more surface area has air exposure. Some soap makers allow for this by curing CP soap a minimum of 4 weeks and HP soap a minimum of 6 weeks.

But there is a method called hot-process soap making that speeds up the time it takes the soap to cure. But, giving soap a full 4 to 6 weeks cure time, at minimum, is important. Step Eleven: Perform a Ph test for safety. 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. 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. Any given fat is a blend of several kinds of fatty acids. The oven temperature setting to dry items in an oven is 180-200 ºF/82-93ºC, which is just below the boiling point of water. 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.

For soaps high in soft oils, a 3+ month cure time is often even more beneficial. It is very important not to sell fresh soap.

After twenty minutes, take mixture out of the oven and stir with wire whisk. In summary, the hot process method only speeds saponification; HP does not shortcut the rest of the cure time. Generally speaking, this takes three to six weeks, but there are some cases when it can take even longer. 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). 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.

Measure the water loss during this time. But once sufficient evaporation happens, the slower process of restructuring the soap then begins. Harden the Soap .

Glycerin, along with table salt and certain other chemicals, has the ability to "salt out" soap when the concentration becomes high enough.
