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 balanced in formulations, helps to ensure the product’s pH is suitable for skin application. While it is a strong substance, in controlled quantities, it is safe and effective in skincare.
Information
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 balanced in formulations, helps to ensure the product’s pH is suitable for skin application. While it is a strong substance, in controlled quantities, it is safe and effective 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.
pH Adjustment: Sodium Hydroxide is primarily used to adjust and maintain the pH level of skincare products, ensuring they are safe and effective for use on the skin.
Product Stability: By helping to achieve the desired pH, Sodium Hydroxide contributes to the overall stability of skincare formulations, preventing ingredients from breaking down or becoming less effective.
Saponification: In soap-making, Sodium Hydroxide is essential for the saponification process, where it reacts with fats or oils to produce soap and glycerin, resulting in a cleansing product that can effectively remove dirt and oils from the skin.
How is it used in our products?
Sodium Hydroxide is used, for example, in B52 Grapefruit Rose Body BalmandB54 Cinnamon Ginger Body Balmfrom OLIVEDA. It is included in very low concentrations and serves as a pH adjuster. It ensures that the product is not too acidic or too alkaline, which is crucial for maintaining the skin’s natural balance and avoiding irritation.
