Hi folks, having had some training in chemistry, it is occurred to me that one of the questions that was originally asked on this thread was how to make liquid laundry soap.
It is also important to understand that when you want to make solid laundry soap or any solid sort for that matter, you use sodium hydroxide. However, what you want to use to make a liquid type of soap is potassium hydroxide in the place of sodium hydroxide.
Potassium hydroxide can be produced by burning Hard wood deliberately and filtering it with distilled water through the ash to collect a relatively high concentration of potassium hydroxide but it will give you some sodium hydroxide. Then you mix it with fats the usual way to make your specific type of soap. The other possibility, is to heat potassium carbonate to a very high temperature and let the carbon dioxide escape leaving potassium oxide which you next mix with water to make potassium hydroxide.
Hope this helps!
