PH regulators&buffers
PH regulators&buffers are key substances used to adjust the acidity and alkalinity of cosmetics, maintaining stability and safety by adjusting the pH value of the product. The human skin and hair are normally in a weakly acidic to neutral slightly acidic state. Cosmetics need to achieve a balance between cleanliness, efficacy, and maintaining the skin's own acid-base balance, so they need to use such ingredients to achieve precise acid-base regulation.
