Sodium Hydroxide

Description

Sodium hydroxide, also known as lye or caustic soda, is a powerful alkaline compound widely used in skincare and cosmetic formulations. This inorganic compound plays a crucial role in adjusting the pH of products, acting as a buffering agent to maintain stability and effectiveness. In small concentrations, sodium hydroxide helps to neutralize acidic ingredients, allowing for better product performance and skin compatibility.

In soap-making, sodium hydroxide is essential for the saponification process, where it reacts with fats and oils to create soap. Its ability to break down proteins makes it useful in chemical peels and hair removal products, though careful formulation is critical to prevent skin irritation. Sodium hydroxide also functions as a penetration enhancer, potentially improving the absorption of other active ingredients.

While highly effective, sodium hydroxide requires precise handling due to its caustic nature. Formulators must carefully balance its concentration to achieve desired results without compromising skin safety. In finished products, the pH is typically adjusted to skin-friendly levels. When properly formulated, sodium hydroxide contributes to product efficacy without posing significant risks to skin health.
