AMMONIUM CHLORIDE

Description

Ammonium chloride is a versatile inorganic compound with the chemical formula NH4Cl. In skincare formulations, it serves multiple purposes, primarily as a pH adjuster and buffering agent. This white crystalline salt dissolves readily in water, creating a slightly acidic solution that can help balance the pH of various skincare products.

As a pH adjuster, ammonium chloride assists in maintaining the stability and efficacy of active ingredients in cosmetic formulations. It's particularly useful in products containing acids or enzymes that require specific pH ranges for optimal performance. Additionally, ammonium chloride functions as an astringent, temporarily tightening and toning the skin.

In some formulations, ammonium chloride acts as a preservative enhancer, supporting the efficacy of other preservatives in the product. It may also contribute to the texture and feel of certain skincare products, particularly in cleansers and exfoliants.

While generally considered safe for topical use in regulated concentrations, some individuals may experience skin irritation or sensitivity to ammonium chloride. As with any skincare ingredient, patch testing is recommended, especially for those with sensitive skin or known allergies.
