lye is an alkaline ingredient in soap making that transforms oils into soap
Lye Soap is made by combining Lye (Sodium hydroxide), Oils and water together at the right temperature and ratio as to begin saponification. Ordinary soap like in the supermarket is not this type of soap. They do not contain lye at all.
Traditional soap-making processes involve using lye (sodium hydroxide or potassium hydroxide) to react with fats to create soap. However, there are now alternative methods to make soap without lye, such as melt-and-pour soap bases that have already undergone the saponification process.
Lye and vegetablew oil or animal fat. Lye is potassium or sodium hydroxide, also known as Caustic potaash or cauatic soda. The oil/fat and lye would be put together and boiled to make soap. Modern soaps are made from palm oil or vegetable oil and sodium hydroxide and boiled together. The given acid of these oils is stearic acid. Hence Sodium hydroxide , and stearic acid makes sodium stearate(soap) and water. Hence the old fashioned trade name for soap as 'palmolive' using oliver oil and palm oil .
Kiss my Face does not disclose their specific soap-making process, but it is possible to make soap without using lye directly by using pre-made soap bases that have already undergone the saponification process. These bases are often referred to as "melt and pour" soap bases. It is also possible to make soap without lye by using alternative methods such as the cold process method with ingredients that naturally contain saponins, like soap nuts.
Lye soap is a classic product that is rarely used currently for commercial use. The most common ingredient in this soap is sodium hydroxide. Other products vary by the manufacturer, but typically include fragrances and fats like lard.

mix lye, water, and fat in large pot. heat and stir. you will get soap.
I cannot suggest anything without some idea of the purpose, for some things (e.g. soap making) there is no practical substitute for lye.
Yes, lye soap is safe to use in fact that is what I use every day. When I was a child, my father used to make lye soap which we all used regularly. Except that it didn't have perfume, it was no different from 'store bought' soap. In previous centuries, many people made and used lye soap.
Hypothesis: If oil and lye are combined in the right proportions and mixed thoroughly, then a chemical reaction will occur that will result in the production of soap. Purpose: The purpose of making soap is to demonstrate the principle of saponification, where fats and oils react with lye to produce soap. This activity also aims to understand the chemistry behind soap-making and the importance of using the correct measurements and techniques to create a useful product.

You cannot make soap without lye. Even glycerin soap is not free of lye. The Lye is a naturally occurring chemical that can be produced using simple rainwater and wood or plant ash. Soap has been made with some form of lye for thousands of years and can be traced back as far as 2800 BC. Here is a website that gives a summary of the history of soap. http://www.cleaning101.com/cleaning/history/ The glycerin is the byproduct that is left over after the commercial soapmakers skim the soap off the top. What is left is then distilled and becomes what we know as glycerin, but the glycerin results from the original process to make the soap which invariably uses lye. The removal of the glycerin from the soap along with the addition of other, God knows what, chemicals added in the commercial soap is what is harmful or drying to your skin. Lye soap (there REALLY is no other kind)is not harmful to your skin IF the soap is properly made. If too much lye is used for the fat content, it may retain some of they lye's caustic properties. Some soapmakers (homemade soap, not commercial) will "super fat" their mixture to avoid any chance that the lye's caustic properties were not neutralized. If you worry about the "chemical" use of lye in your soap, don't be. Without lye, there is no soap. Water, Lye and Fat are the ingredients in any soap. The only alternative is detergent which is made with phosphates. Phosphates are carcenogenic and are known to cause cancer. Also, don't forget the potential for chemical harm attributable to glycerin either. Nitroglycerin is made from glycerin! When used and handled properly, lye is very safe.
