Are soaps characterized as highly alkaline?

Soaps are indeed characterized as highly alkaline due to their chemical composition. When making soap, a process called saponification occurs, where fats or oils are mixed with an alkali, typically sodium hydroxide or potassium hydroxide. This reaction produces soap and glycerin.

The resulting soap solution has a high pH, often around 9 to 10, which classifies it as alkaline. This alkaline nature is important because it helps in the removal of dirt and oils from the skin. The high pH can also contribute to the antimicrobial properties of soap, making it effective for cleansing.

Understanding the properties of soaps, including their alkalinity, is crucial for estheticians as it affects how they incorporate soap into skincare routines and the potential impact on different skin types. High alkalinity can be harsh on sensitive skin, emphasizing the need to choose appropriate cleansing products based on skin conditions.
