Cold Process / Oven Process Method

by Hayley

I have just heard about this CP/ Oven Process Method. I've not come across it before. You make your soap CP and then put it in the oven at 170F for 2 1/2 hrs, then switch oven off and let soap mould sit in there overnight. Apparently, this is like CP but your soap is ready to use immedietly without curing.

Would you let us know what you think about this? Does it really not need to cure after? I use Room Temperature method as its super easy. Do you think Room Temp method would work with this oven method also?

I am very grateful for your time and expertise in answering.

Answer:

To be honest, I'm always skeptical of "short cuts".

Can you use the soap right after if has been made without curing? Probably...but then again you can use any soap right after it has been made....unfortunately it tends to be extremely drying and the soap is quite soft....not very healthy for your skin.

I'm having a hard time seeing the difference between the cp oven process and regular cp process soap....it looks like the oven just takes the place of the insulating blankets and jump starts the gel phase.

I guess what I mean to say is that besides the obvious differences...what factor makes the oven process soap ready to use right away? I can't see anything to indicate that the soap could skip the cure phase.

Since I've never tried this method, I can't say whether or not you can skip the cure stage.

To find out, I would suggest making two batches...one using your regular method and the other using the cp oven process. Once each soap has cooled completely and can be cut, try a piece of each soap to see if there is a difference.

Here is a good way to tell the difference between each bar. Put on a single rubber glove and wash your bare hand with one soap. Then do the same using the other glove and soap. If there is a substantial difference between the soaps you should be able to feel it.

Let me know your results if you give it a try...I would love to hear about it.

I have tried the cpop and I think I prefer this method. It does work. I like how you leave it in the oven instead of towels insulating and it is finished sooner. You just have to let the water evoporate out a few days.

I did that with different pieces from the same batch. the two pieces in the oven changed drastically the colour. they became very dark... a horrible colour.
with another batch with honey... the pieces from the oven .... the glycerin got separated and started runing pver the mould edges. and the honey got burnt. a pungeount smell of burnt honey/glucose.
I only had bad experienced with cpop. especially when it comes to colour change.... they all became dark. very dark. I could show you pictures if there is any way to upload.
I don't like that! even though i get an ununiform colour on my soaps.... sometimes in the middle i get a darker area... i prefer them as they are without oven process.

170C is too hot, you do not want to cook the soap. The oven should be at 70C.

I believe the instructions are for 170 degrees Fahrenheit NOT Celsius.

How long do you leave the soap in at 170F? I read somewhere you put the soap in and then turn off the oven where you leave your soap in overnight. Has anyone had luck with this? I'm very new to soap making.
Also interesting was reading that even though the soap is ready to use, it can be very dryig to the skin. I guess curing is the only way the soap becomes moisturizing.

I use the cpop method exclusively in making my soap. I use a olive oil/soybean oil blend, and use coconut milk as my liquid for mixing my lye. I usually have my ingredients at about 95 degrees before combining. I set the oven temperature at 195 degrees and stir after the first 30 minutes, then every 15-20 minutes until done. This is a very easy method and I have had great success making it. The only downside I have found is that the soap sets up rather quickly when it is time to pour. You have to work fast.

Sounds like a short cut that should not be shorten!

I made my first batch of cpop. It turned out great! I set the oven for 170 for 1 hour. I then turned the oven off and left the soap in the oven for 12 hours. It is beautiful and popped right out of the mold. The other thing I noticed is that there was absolutely NO soda ash! Hopefully, none will surface. I will try this method again,
