Ok, I know this question has been asked, and I have tried to search it, and read what I found, but honestly, it's like reading a different language. I've really never used a preservative other than vitamin E, if that even is one.
I'm making a huge batch of liquid castile, and an almost huge batch of scented liquid soap for someone else, and I'd like to make sure it'll be alright for her to keep. I make smaller batches for my family use, but we go through it pretty quick, and I really don't make it to sell because of the time it takes, and I'm very impatient
Any help on what to use would be great! I don't want to use anything containing propylene glycol, I know a lot of people don't mind it, but I just won't use it, or products that contain it except anti freeze from my car.
