Sodium Malate

1. Definition Sodium Malate:

Sodium Malate is a sodium salt of malic acid, which is a naturally occurring organic acid found in fruits such as apples. It is commonly used in cosmetics as a pH adjuster, buffering agent, and antioxidant.

2. Use:

Sodium Malate is used in cosmetics to help adjust the pH of formulations to ensure they are gentle and non-irritating to the skin. It also acts as a buffering agent, helping to stabilize the pH of a product over time. Additionally, Sodium Malate has antioxidant properties, which can help protect the skin from damage caused by free radicals.

3. Usage Sodium Malate:

Sodium Malate is typically used in small concentrations in cosmetic formulations, usually around 0.1-1%. It is considered safe for use in cosmetics, but as with any ingredient, it is important to follow recommended usage levels to avoid potential irritation or sensitization. It is important to conduct a patch test before using products containing Sodium Malate, especially for individuals with sensitive skin.
