AMMONIUM THIOCYANATE

Description

Ammonium thiocyanate is a versatile inorganic compound with the chemical formula NH���SCN. This white, crystalline solid is highly soluble in water and polar organic solvents, making it a valuable ingredient in various skincare formulations. In cosmetic applications, ammonium thiocyanate primarily functions as a preservative and antimicrobial agent, helping to extend the shelf life of products and protect against bacterial contamination.

The compound's ability to form complexes with metal ions gives it additional utility in skincare. It can act as a chelating agent, binding to metal ions that may otherwise contribute to oxidative stress or product instability. This property makes ammonium thiocyanate particularly useful in formulations containing antioxidants or sensitive active ingredients.

In some formulations, ammonium thiocyanate may also serve as a pH adjuster, helping to maintain optimal acidity levels for product efficacy and skin compatibility. Its use is typically limited to low concentrations due to potential irritation at higher levels. When incorporating ammonium thiocyanate into skincare products, formulators must carefully balance its beneficial properties with potential sensitivities, especially for individuals with reactive skin types. Proper testing and adherence to regulatory guidelines are essential to ensure safe and effective use of this ingredient in cosmetic applications.
