I was asked as I often am about what the difference is between regular soap like a traditionally made soap and glycerin soaps is.
Well, as best as I can explain it and with the help of stealing some text from Wikipedia...
Traditional soaps are a chemical reaction between an acid (oil) and a base or caustic material (lye) whereby the materials combine to create something completely different and without any of the original (well mostly) materials left over. The reaction is called Saponification and soap is created.
When we make soap one of the byproducts is glycerine and.....
Glycerin soaps are soaps that contain glycerin, a component of fat or oil. The soap is recognizably different from other soaps because it is translucent. The clarity of the soap is due to the particular alignment of the soap molecules in this type of soap, which can be induced through the addition of alcohol and sugar. This is usually done for homemade glycerin soaps which are not remeltable.
The process for making glycerin soaps was well known as of 1857 in the Western world. In modern industrial soap-making, the glycerin is then usually separated from the soap to be resold and used in a wide variety of areas such as for personal care products, pharmaceuticals, chemical intermediates, and food processing.....mostly food processing.
Glycerin soap is made by melting and continuously heating soap that has been partially dissolved in a high percentage alcohol solution until the mixture reaches a clear, jelly-like consistency. The alcohol is added to a slow cooked hot-processed soap and then simmered with a sugar solution until the soap is clear or translucent, and then the simmered soap is chilled in a freezer. With home- and hand-made soaps that still contain glycerin left over from saponification the grating, melting and cooking can proceed without the addition of anything into the mixture, though sugar or more glycerin is sometimes added. Glycerin soap can also be produced without remelting soap through directly cooking raw home-made soap.
Modern clear glycerin soaps bases are produced by combining various glycerol and polyols with soap and other surfactants in a manner similar to traditional glycerin soap making methods. These modern clear soaps have the benefit of being easily re-meltable and are often sold in bulk to customers for melt-and-pour soap crafting.
For my store I have made up for me a pure vegan glycerine soap to my standards and formula. This soap is a very gentle, purely cleansing products that holds the essential oils cleanly and clearly......a super nice product.
