pH Adjuster

Description

pH adjusters are crucial components in skincare and cosmetic formulations, serving to stabilize and optimize the acidity or alkalinity of products. These ingredients play a vital role in maintaining the effectiveness, safety, and stability of various skincare formulations. Common pH adjusters include citric acid, lactic acid, sodium hydroxide, and triethanolamine.

The primary function of pH adjusters is to ensure that products remain within a specific pH range, typically between 3.5 and 8.0, depending on the formulation's intended purpose. This pH control is essential for several reasons: it helps preserve the product by inhibiting microbial growth, maintains the stability of active ingredients, and ensures that the product is compatible with the skin's natural pH (around 4.5-6.5).

pH adjusters also play a role in optimizing the performance of other ingredients in the formulation. For example, certain active ingredients may require a specific pH range to function effectively. Additionally, controlling pH can influence the texture, viscosity, and overall sensory experience of the product. When formulating skincare products, it's crucial to select pH adjusters that are compatible with other ingredients and suitable for the intended skin type and product function.
