Mineral oil is totally unsaponifiable, since it is derived from petroleum and doesn't have the same chemical composition as plant and animal fats. I wouldn't think it would work as a substitute for castor oil.
I just picked up some waste beef fat from my local supermarket, and I'm going to render it this weekend into soap-ready tallow. Other than that, I have just made a peppermint-scented 1-lb. batch of tomato juice salt bars that are waiting to set in the mold before I take them out to cure...
Rumor has it that activated charcoal results in a nice black soap, but I have yet to try it in a recipe. I'd think that the charcoal might lessen some of the soap's fragrance due to its odor-absorbing properties.
I'm attempting yet another experimental batch - a salt bar with tomato juice. I'm aiming for a 15% superfat to keep the bar smooth. Here are the ingredients that I've used:
6.10 oz. tomato juice
2.22 oz. lye
14 oz. coconut oil
2 oz. castor oil...
Don't forget to pick up a stick blender! However, when making my first three batches, I stirred the soap manually just to get a feel of what it's like (plus, I used fats that resulted in faster trace, like lard and coconut oil).
I got to testing one of my shampoo bars on my hair, and this batch was INCREDIBLE! The lather was smooth and perfect, and felt really good on my hair. I don't think I ever want to go back to using Head & Shoulders ever again.
Next: I will need to use this shampoo on a long-term...
The trouble with U.S. measurements is that there are many different meanings of the word "ounce" -- it could be a fluid ounce (volume), a troy ounce (weight), or an avoirdupois (also weight), all of which mean different things.
Most of the time, when we talk about an "ounce" we refer to the...
It's funny that you mention Mother's Day! In my weekend soap pot, I'll be making a batch for my mother-in-law, with the opportunity to test out some decorative soap molds that I picked up.
This will be a one-pound batch consisting of 75% lard and 25% coconut oil, scented with lavender EO and...
I just took notice, also, that many "store-brand" vegetable shortenings are formulated similar to "Old" Crisco. I might try using some to see how it turns out in soap, but I wouldn't eat any of it in a million years -- it's too much trans fat for my diet...
A number of years back, Crisco reformulated their shortening products to result in fewer trans fats. They switched from this ingredient list:
to this ingredient list:
For those who soap with Crisco, did this affect the performance of the soap after using the reformulated Crisco...
