SODIUM CITRATE
Description
Sodium citrate is a versatile compound widely used in skincare and cosmetic formulations. This salt of citric acid serves multiple functions, including pH adjustment, chelation, and buffering. Its ability to regulate acidity makes it valuable for maintaining product stability and optimizing the effectiveness of other active ingredients.
In skincare, sodium citrate acts as a gentle exfoliant by promoting cell turnover and improving skin texture. It also exhibits mild antimicrobial properties, which can help in managing acne-prone skin. As a chelating agent, it binds to metal ions, preventing them from interfering with product performance and potentially irritating the skin.
The ingredient's buffering capacity helps create a more favorable environment for sensitive skin by reducing potential irritation from acidic or alkaline substances. Sodium citrate also enhances the penetration of certain active ingredients, improving their efficacy.
Its humectant properties contribute to skin hydration, helping to maintain moisture balance. Additionally, sodium citrate possesses antioxidant characteristics, offering some protection against free radical damage. Its safety profile is well-established, making it suitable for a wide range of skincare products, from cleansers and toners to serums and moisturizers.
