Sodium Citrate

Description

Sodium Citrate is a versatile and widely used ingredient in skincare formulations, serving multiple purposes in various products. This salt of citric acid is known for its ability to act as a pH buffer, helping to maintain the optimal acidity level of skincare products. This function is crucial for preserving the stability and efficacy of other active ingredients, as well as ensuring the product remains gentle on the skin.

In addition to its buffering properties, Sodium Citrate exhibits mild exfoliating effects, which can help improve skin texture and promote a brighter complexion. It also functions as a chelating agent, binding to metal ions that could otherwise destabilize formulations or irritate sensitive skin.

Sodium Citrate's humectant properties contribute to skin hydration by attracting and retaining moisture. This makes it a valuable addition to moisturizers and serums. Furthermore, its ability to enhance the penetration of other ingredients can improve the overall effectiveness of skincare formulations.

While generally well-tolerated, Sodium Citrate may cause mild irritation in some individuals with extremely sensitive skin. Its use in skincare products is considered safe and effective by regulatory bodies worldwide.
