pH Adjuster

pH adjusters are substances that are added to cosmetics to either raise or lower the pH level of a product. The pH level of a cosmetic product is important because it can affect how the product interacts with the skin. The skin's natural pH is slightly acidic, typically around 4.5 to 5.5, so it is important for cosmetic products to be formulated within this range to avoid causing irritation or other issues.

pH adjusters are important in cosmetics for several reasons. First and foremost, they help to ensure that a product is safe and gentle on the skin. If a product is too acidic or too alkaline, it can cause irritation, redness, or other adverse reactions. By adjusting the pH level to match the skin's natural acidity, pH adjusters help to minimize the risk of these issues.
Furthermore, pH adjusters can also impact the stability and efficacy of a product. Certain ingredients may require a specific pH level to remain stable and effective, so pH adjusters are used to ensure that these ingredients perform as intended. For example, vitamin C-based products typically require a slightly acidic pH to remain stable and effective, so pH adjusters are used to maintain this pH level.
