The lather that castor oil produces is what really makes it such an appealing ingredient for soap making. You need to actually try using castor oil soap to truly appreciate how wonderful the lather is... I can guarantee you won't be disappointed!

In addition to the wonderful lather, the conditioning and moisturizing properties that this ingredient adds is a great bonus for using castor oil for soap making.

Keep in mind that you don't need to use a huge amount of castor oil in order to see the benefits in your soap. I recommend keeping it at around 5% - 10% of the total oils used in your batch. While using the right amount of castor oil will reap incomparable benefits in your soap, If you incorporate too much, your soap may feel a bit sticky and soft. You definitely don't want that!

Using castor oil for soap making also seems to speed up trace somewhat. For this reason, it's a good idea to adjust your soaping routine accordingly. You can soap cooler to slow down trace. When using castor oil, I combine the lye and oils at around 90 degrees (which for me is a lower temperature then normal) to avoid an overly quick trace. Also, if you are the type of soap maker that uses a stick blender, you may want to cut down the amount of time that you use the device and stir more manually. This, however, is not really necessary for most soap makers... especially those who have some experience.

When using a stick blender for too long when making castor oil soap, trace could potentially sneak up on you and your soap may quickly become too thick to pour into a mold. When stirring manually, there will be less risk of accidental seizing that some beginners experience.
