Whipped handmade soap

*This post was originally done back in 2008 but I did update today, November 07, 2012 with new links inside that have been missing from 2008.  Over the years, bloggers change, links change… life change basically…!

Fragrance oil : none
Shredded soap (1 bar, any soap will do here, either handmade or store one, if you shred a very colorful soap, it will look even nicer)
20 oz of a recipe of the following:
Olive oil
Now here, the quantity for each fats is not given because… it all depends on how much I had on hand, when I did this particular recipe.
To make a whipped soap, the important thing is in the process of making it whipped and not so much in the ingredients used.
For example: lets take those three main fat ingredients and use this site to determine and to build the entire recipe.



For the size of fat batch that you are using, we recommend that you use approximately 5 to 8 fluid ounces of liquid.

WARNING: Always add your solid form lye, sodium hydroxide or potassium hydroxide, to the liquid. If the liquid were added to the solid form lye a violent reaction could result. This means you could have a “volcano” erupt out of your container.

10 2.48

So as you can see, it is pretty simple.  I had on hand : 2 oz of canola oil, 6 oz of olive oil and 12 oz of lard (pig lard).  On the first page of the site, I just entered my number in relation to my end result of having a 20 oz recipe.  I used just plain water as liquid.  Then, press on Calculate and the site will build the recipe for you.

Measure your liquid to 5 oz (I always take the small amount given), measure the powder lye, here for example I use 5% so it will be 2.61 oz of lye.


I do that step first, usually outside, wearing appropriate gloves and long sleeves and a face mask with safety glasses.

The lye-water mix will get very hot, be careful here.  Mix well until all is melted.  Get back to your kitchen and proceed in following this process below:

I wanted to create a confetti white soap, with no fragrance what so ever. So this is what I just made a few minutes ago.

Whip the lard into a fluffy cream with a mixer, at room temperature.

Add slowly the canola and olive oil and bring it back to a fluffy cream.

Add the lye-water mix, that was previously made earlier during the day so the mix is no longer hot, but cold. Keep mixing until reaching a cream like mix.

Add the shredded soap, mix slowly.

Cheap plastic containers, anything will do when doing the Cold pressed method

*Here a great youtube video on how to line any mold for cold pressed soap, very easy, very smartly done, the best

Drop half of the mixture into the mold (since I have a 20 oz recipe, take in consideration that you will need a container that can hold 20 oz here, ok?), sprinkle a very thin layer of red oxide if you want and cover the rest with the left over soap mixture.

Place a piece of plastic wrap over the top and let if sleep until hard.

This is a cold process soap because I want the shredded soap to stay in little pieces and not be melted in the oven, like in the process of HPS (Hot Process Soap). I will check this soap before going to bed.

Update : Dec 04, to cut this soap, I had to be patient. It takes from 24 to 36hrs to dry. Even this morning it is still soft but I was able to cut it.

I think if I wait too long to cut it, it would become to dry and I would not get the clean lines. This final product looks like a piece of cake with the icing on top. Very nice.

A different way of making soaps.

Now, to repeat myself here, to know if your soap is ready to be used on your beautiful skins, do the “tongue” test… which is : like if you were tasting the power of a little battery.

Take the soap, cut up, place the tip of your tongue on the soap, very lightly.  If you get like an electric shock, like if you were testing a battery, it means that your soap is not ready to be used and that the lye inside the fresh soap is still maturing, not ready to be used, simple.

The soap will be ready when and only when your tongue, once touching the soap, gets that soapy taste and not that snappy burning taste.  Simple test to do, and pretty safe!  This test never fails… never… lye is a chemical and it burns when it is not cured or ripe or mature enough.  Ok?

One last thing, stop by this site, where this person explains more in detail, on how to make whipped soap.
