hello Tabitha,
thank you for your reply! I'll try to use yolk egg, and i add when i put my addictives. I think that the soap has preservatives and the egg doesn't rot.
If i'm wrong please correct me.
I don't know about the eggs, but I know people have done it. As far as the beer, yes you can use it as your water, but make sure it is VERY VERY flat. Let it set for a day or two before using it.
I *think* if you want the soap to have presrvative you have to choose the correct one & add it. I could be wrong too though. I know if you add fresh fruit w/o a preserve it will rot.
I have only made about 8 batches of cp myself & that was 4-5 years ago, I am a B&B maker & only dabbled in the cp...
I regularly make a CP beer soap. No FO of EO needed, it smells great as is.
I use 100% Flat -VERY FLAT beer instead of water. Make sure it has sat out on the counter, opened for a few days. Otherwise it will create quite a mess when the lye is added to it.
Can't help you with the egg, sorry!
