Cold pressed soap has gained popularity in recent years due to its natural ingredients and gentle properties. One of the key components in the soap-making process is lye, which plays a vital role in creating a safe and effective bar of soap. In this blog post, we will explore the function of lye in cold pressed soap and address common concerns regarding its potential harm after saponification.
What is Lye? Lye, also known as sodium hydroxide, is a highly alkaline substance that is essential in the soap-making process. It is created by combining sodium hydroxide with water. When mixed with oils or fats during soap production, lye undergoes a chemical reaction called saponification, resulting in the formation of soap and glycerin.
The Function of Lye in Cold Pressed Soap:
Lye serves as a catalyst in the saponification process, where it facilitates the conversion of oils or fats into soap. During saponification, lye molecules react with the fatty acids present in the oils, breaking them down and rearranging them to form soap molecules. This reaction, when carried out properly, results in a gentle and cleansing bar of soap.
Dispelling the Lye Safety Concerns:
There is a common misconception that lye in soap can be harmful to the skin. However, it's important to note that once the saponification process is complete, there is no remaining lye in the finished product. Through the chemical reaction, lye is entirely transformed into soap and glycerin. Cold pressed soap, when made correctly, is pH-balanced and gentle on the skin.
Understanding the Importance of Precise Measurements:
To ensure the safety and efficacy of cold pressed soap, it is crucial to follow precise measurements when working with lye. Soap makers carefully calculate the amount of lye required based on the specific oils or fats being used. This precision guarantees that all lye is fully saponified, leaving behind no excess or potentially harmful residue.
The Curing Process:
After the soap is initially made, it goes through a curing process that typically lasts for several weeks. During this time, any residual moisture and excess lye continue to evaporate, resulting in a milder and harder bar of soap. Proper curing ensures that the soap is gentle on the skin and allows it to last longer.
Lye is an essential component in cold pressed soap, playing a crucial role in the saponification process. Contrary to common misconceptions, once the soap is properly made and cured, there is no lye remaining in the final product. Cold pressed soap made with precise measurements and allowed to cure adequately is safe, gentle, and beneficial for the skin. This distinction ensures that cold-pressed soap made with lye is free from any active lye, while the presence of additives in shower gels can vary depending on the formulation. It's essential to understand the chemistry and science behind soap-making to debunk myths surrounding lye. By educating ourselves, we can appreciate the craftsmanship and benefits of cold pressed soap, confidently incorporating it into our skincare routines.
