Silver Chloride
What is Silver Chloride?
Silver chloride (AgCl) is an inorganic compound, a white, odorless powder consisting of silver and chloride ions, often derived synthetically for purity in formulations. It appears naturally in mineral forms but is processed for cosmetic applications. In skincare, it falls under antimicrobial preservatives, commonly incorporated into creams, lotions, cleansers, and eye-area products. Functionally, its sparingly soluble nature allows gradual release of silver ions in the presence of moisture. These ions target microbial cells by binding to enzymes, disrupting respiration, and damaging cell walls, thereby inhibiting bacteria and fungi proliferation. This mechanism supports product integrity against contamination from handling, air exposure, or repeated use, without broadly affecting product texture or efficacy.
