SODIUM PROPIONATE

Description

Sodium propionate is a versatile preservative and antimicrobial agent widely used in skincare and cosmetic formulations. This white, crystalline powder is the sodium salt of propionic acid, a naturally occurring short-chain fatty acid. Its primary function is to inhibit the growth of mold and bacteria, thereby extending the shelf life of products and ensuring their safety for consumers.

In skincare applications, sodium propionate is particularly effective against fungi and some bacteria, making it valuable in formulations prone to microbial contamination. It operates optimally in slightly acidic to neutral pH environments, making it compatible with a wide range of product types. This ingredient is water-soluble and typically used at concentrations between 0.1% and 0.5%, depending on the formulation requirements.

Sodium propionate is considered gentle and well-tolerated by most skin types, making it suitable for use in sensitive skin formulations. It works synergistically with other preservatives, enhancing overall product protection. Additionally, it has GRAS (Generally Recognized as Safe) status from the FDA, further attesting to its safety profile. While primarily used as a preservative, sodium propionate also exhibits mild anti-inflammatory properties, potentially offering secondary skincare benefits.
