SODIUM FERROCYANIDE

Description

Sodium ferrocyanide, also known as yellow prussiate of soda, is a complex inorganic compound with the chemical formula Na���[Fe(CN)���]. This water-soluble salt is characterized by its pale yellow color and cubic crystal structure. In skincare formulations, sodium ferrocyanide serves primarily as a stabilizing agent and pH adjuster.

The compound's ability to form stable complexes with metal ions makes it valuable in preventing oxidation and maintaining product integrity. It can help preserve the color and efficacy of formulations containing sensitive ingredients. Sodium ferrocyanide also exhibits mild antimicrobial properties, potentially contributing to the preservation of skincare products.

In terms of safety, sodium ferrocyanide is generally recognized as safe (GRAS) by the FDA for use in cosmetics and personal care products. However, its concentration in formulations is typically low due to regulatory limits. It's important to note that despite containing cyanide groups, sodium ferrocyanide does not readily release free cyanide under normal conditions, making it safe for topical use.

When formulating with sodium ferrocyanide, careful consideration must be given to pH levels and potential interactions with other ingredients to ensure optimal stability and efficacy of the final product.
