I thank you for the replies. I am trying to find a non-toxic alternative like corn starch.
I have tried to add some corn starch to the soap but it doesn't thicken.
Do I have to heat the mixture in a double boiler?? and if so for how long?
I have tried two ways now.
I know I have to heat the cornstarch and water to get a thickening agent (like making gravy) but it didn't thicken the soap when I added it and let it set for a day.
The second way I tried it I heated the whole mixture of cornstarch and soap, directly on the element, I even tried adding gelatine.
I just answered this thread but my post is gone. Or are there two threads on thickening liquid soap?
I suggest you read Catherine Failor's "Making Natural Liquid Soaps." I advise you see if your local public library has it. I've read it and it has a bunch of good information although I don't recall thickening. She provides recipes and directions. She's a very accomplished soaper and author.
