What is it?
Sodium Hydroxide is a highly alkaline compound used in small amounts in skincare formulations primarily to adjust the pH levels of products. It is a powerful base that, when properly utilized in formulations, can ensure the product’s pH is suitable for skin application. While it is a strong substance, in controlled quantities, it is safe and ideal in skincare.
Where does it come from?
Sodium Hydroxide is typically produced through the electrolysis of sodium chloride (table salt) in water. This process, known as the chloralkali process, separates the sodium ions, which combine with hydroxide ions in water to form Sodium Hydroxide.
