AMMONIUM BENZOATE
Description
Ammonium benzoate is a versatile preservative widely used in cosmetic and personal care products. This white, crystalline compound is the ammonium salt of benzoic acid, known for its antimicrobial properties against bacteria, yeasts, and molds. With the chemical formula NH4C7H5O2, ammonium benzoate effectively inhibits microbial growth in a variety of formulations, particularly those with acidic to neutral pH levels.
In skincare and cosmetic applications, ammonium benzoate serves as an excellent alternative to parabens, offering broad-spectrum preservation without some of the concerns associated with other preservatives. It is especially effective in water-based products such as lotions, creams, and liquid foundations. The ingredient's solubility in water makes it easy to incorporate into formulations, ensuring even distribution throughout the product.
Ammonium benzoate is generally considered safe for use in concentrations up to 0.5% in leave-on products and up to 2.5% in rinse-off formulations. It works synergistically with other preservatives, enhancing overall product stability and shelf life. While some individuals may experience sensitivity, ammonium benzoate is typically well-tolerated by most skin types, making it a valuable component in modern skincare formulations.
