What are the differences between MP, Cp, CPOP & HP?

24 May

When I first started making soap, I thought there was only one way. I was wrong! There are actually many ways to make soap.  Here are the descriptions of the ways in which you can make soap.

MP = Melt & Pour

Melt and pour is just that. You buy the base, melt it and pour it.   Pretty simple that’s why it’s a great choice for the beginner.

CP = Cold Process

You mix a specific amount of Sodium Hydroxide (Lye) & liquids together. Then you let that mixture cool to the correct temperature. You then add it to the oils and/or butters at their correct temperatures.  There is no heat applied.  After properly mixing the lye and oils and/or butters together you place the mixture into a mold.  Then insulate with towels…. The chemical reaction (Saponification) will produce heat when in the mold. After 10 to 24 hours you unmold the soap. The Saponification (the chemical reaction that creates soap) is not complete for another 4 to 6 weeks. Those weeks are called the “curing” period.

CPOP = Cold Process Oven Process

This process is the same as Cold Process instead of insulating you place the mold into a preheated 170 degree oven for one hour. Then you shut the oven off, some people leave the soap in the oven overnight others take it out after a few hours.  Some say there is no need for a “curing” period. I’ve never tried this method but I think I’d still cure it.

HP = Hot Process

This is the process where you “cook” the soap.  You mix the Lye and water together. Then you add the lye solution to the oils and/or butters. In a pot or crock pot. I use a Crock pot. The Temperature does not matter because you’ll be cooking it. After adding the lye solution to the oils and /or butters you bring it to a thick trace w/ your stick blender. Then you turn the crock pot onto low and let it cook. You’ll check on it every now and then to make sure it doesn’t cook over the edge of the pot. When the entire mixture looks like Vaseline it’s time to add fragrance or other additives. Then pack it into molds. When it’s hard it’s done. Unlike CP this soap doesn’t have to cure.

      To tell you the truth I’ve never done the melt & pour. So, I’m not sure which brand.
