SODIUM SORBATE
Description
Sodium sorbate is a versatile preservative widely used in skincare and cosmetic formulations. This sodium salt of sorbic acid is derived from natural sources, primarily berries of the mountain ash tree. It functions as an antimicrobial agent, effectively inhibiting the growth of molds, yeasts, and certain bacteria in personal care products.
With a molecular formula of C6H7NaO2, sodium sorbate is water-soluble and works optimally in formulations with a pH range of 4.5 to 6.5. Its efficacy is particularly notable in acidic environments, making it an excellent choice for many skincare products. This ingredient is generally considered safe for topical use and is approved by various regulatory bodies worldwide.
Sodium sorbate offers several advantages in product formulation. It has a mild, non-irritating nature, making it suitable for sensitive skin types. The ingredient is odorless and colorless, ensuring it doesn't alter the sensory properties of the final product. Additionally, sodium sorbate is compatible with a wide range of other cosmetic ingredients, allowing for versatile formulation options.
While primarily used as a preservative, sodium sorbate may also exhibit slight antioxidant properties, potentially contributing to the overall stability of skincare formulations.
