What is lye?
Lye is a very alkaline product that has been used to make soap for decades. It also has uses in other industries, such as food and cleaning. Lye is a general term for two different alkaline compounds known as Sodium Hydroxide (NaOH) and Potassium Hydroxide (KOH). They are both metal hydroxides and basic alkaline, so they have a very high pH. The high pH makes this mixture very caustic, which means that if you don't protect your skin when you touch it at this stage, it can cause a chemical burn. These two compounds are highly water-soluble and are sometimes referred to as caustic soda.
Though this may sound odd to put in soap, the chemical reactions that occur later in the soapmaking process, called saponification, neutralize the lye in the soap while activating its cleaning power.
What is Lye Soap?
Lye soap, also known as caustic soap, is a handmade soap created through a chemical reaction between lye (a strong alkaline solution) and fats or oils. This process, called saponification, breaks down the fats into fatty acids and glycerol, forming soap molecules. The soap molecules have a hydrophilic (water-loving) head and a hydrophobic (water-hating) tail, enabling them to effectively remove dirt and oil from surfaces.
The choice of lye (sodium hydroxide or potassium hydroxide) determines the hardness of the soap. Sodium hydroxide produces harder bars, while potassium hydroxide results in softer, creamier soaps. The type of fats or oils used also influences the soap's characteristics, such as its lather, scent, and moisturizing properties.
Making lye soap requires careful handling of lye, as it can cause severe burns if not used properly. It's essential to follow specific instructions, wear protective gear, and work in a well-ventilated area. The process involves heating the lye and fats or oils separately, then combining them to initiate the saponification reaction. The mixture is typically heated and stirred until it reaches trace, a point at which the soap thickens and begins to set.
