AMMONIUM ACETATE

Description

Ammonium acetate is a versatile compound used in various skincare formulations due to its multifaceted properties. This colorless, crystalline salt is composed of ammonium and acetate ions, making it highly soluble in water. In skincare, ammonium acetate primarily functions as a pH adjuster and buffering agent, helping to maintain the optimal acidity of products for skin compatibility and stability.

The ingredient's ability to regulate pH is crucial in preserving the efficacy of active ingredients and ensuring product safety. Ammonium acetate also exhibits mild antimicrobial properties, which can contribute to the preservation of skincare formulations. Its hygroscopic nature allows it to attract and retain moisture, potentially aiding in hydration when used in appropriate concentrations.

In some formulations, ammonium acetate may serve as a penetration enhancer, facilitating the absorption of other beneficial ingredients. It's generally considered safe for topical use and is well-tolerated by most skin types. However, as with any ingredient, individual sensitivities may occur. Formulators often incorporate ammonium acetate in small amounts to achieve desired pH levels and stability in various skincare products, including cleansers, toners, and serums.
