pH regulator
pH regulators in cosmetics:
Application and Benefits
The pH value of cosmetic products plays a crucial role in their effectiveness and skin compatibility. Products that do not have the correct pH value can cause skin irritation and compromise the skin's protective barrier. This is why the use of pH regulators in cosmetic formulations is essential.
In this blog you will learn more about the function and importance of these substances in cosmetics.
What are pH regulators?
pH regulators are ingredients used in cosmetic products to stabilize the pH of the formulation. The optimal pH for the skin is slightly acidic, between 4.5 and 5.5. Products with an incorrect pH can dry out or irritate the skin. pH regulators ensure that the value remains in the desired range and that the products are skin-friendly and effective.
Types of pH regulators
There are different types of pH regulators used in cosmetic formulations. They can be divided into acidifying and alkaline substances, depending on whether they are intended to lower or raise the pH value.
Acid-forming pH regulators:
Lactic acid (INCI: Lactic Acid)
citric acid (INCI: Citric Acid)
tartaric acid (INCI: Tartaric Acid)
Alkaline pH regulators:
Sodium hydroxide (INCI: Sodium Hydroxide)
Potassium hydroxide (INCI: Potassium Hydroxide)
Triethanolamin (INCI: Triethanolamine)
Applications and Benefits
pH regulators are used in a wide range of cosmetic products, including skin care, hair care and color cosmetics. They not only ensure that the pH value of the products remains skin-friendly, but also contribute to the stability of the formulation. This is particularly important to ensure the effectiveness of the active ingredients and to extend the shelf life of the product.
