CITRATE BUFFER

Description

Citrate buffer is a versatile and widely used pH-regulating agent in skincare and cosmetic formulations. This ingredient is composed of citric acid and its conjugate base, typically sodium citrate. Citrate buffer effectively maintains the stability of products by controlling their acidity levels, which is crucial for preserving the efficacy of active ingredients and ensuring product safety.

In skincare formulations, citrate buffer plays a vital role in optimizing the pH for various ingredients to function effectively. It helps create an environment that enhances the penetration of active ingredients into the skin, particularly beneficial for products containing alpha-hydroxy acids (AHAs) or vitamin C. The buffer's ability to maintain a stable pH also contributes to the overall shelf life of the product.

Citrate buffer is generally well-tolerated by most skin types and is considered safe for use in cosmetic applications. Its natural occurrence in citrus fruits makes it an appealing choice for formulators seeking clean and naturally-derived ingredients. Additionally, citrate buffer can act as a mild chelating agent, helping to improve product stability by binding to metal ions that could potentially cause oxidation or degradation of other ingredients.
