Hi all, I'm new here, but have been making soap for a while. Crisco, which is vegetable shortening, is not bad for your skin, nor is animal fat. The chemical reaction that takes place between the oils & the lye renders an entirely new compound, soap, which is a salt.
I personally use olive oil and coconut oil as my "base" oils, adding more exotic oils for their various properties. I don't use lard or tallow because I personally don't like the end results in my soap, although I will use lard to make laundry soap.
A few good pointers for beginning soap makers are
1. Keep it simple. Don't be tempted to add a lot of "stuff" to your soap, like color, fragrance, EO's etc. Get a basic recipe down first, then start playing with it.
2. Use a GOOD, RELIABLE lye calculator.
3. Do share your soap with friends & family. Let them test it out for you.
4. Get to know the different oils used in soap making, and learn what properties each one is adding to your soap. Coconut oil and Castor oil both give LOTS of bubbles, but can be drying, so they need to be paired with other more nourishing oils.
5. Have fun with it, but be careful. Yes, it is an EXACT science, if you don't follow the measurements to a T, you can end up with a harsh bar of soap.
6. Get a reliable DIGITAL scale and measure EVERYTHING by weight. I use grams because I can get a more accurate measurement than with ounces.
Most of all...enjoy making something that is good for your skin
I look forward to getting to know you all on here
