Used in testing the durability and colorfastness of textiles, artificial sweat helps evaluate how fabrics and dyes react under conditions simulating human perspiration. It is essential in assessing the safety and performance of clothing, especially sportswear and undergarments, by determining if harmful substances such as heavy metals or allergenic dyes leach out when in contact with skin. The solution is also used in evaluating the corrosion resistance of metals and coatings in watches, jewelry, and electronic devices exposed to sweat. Additionally, it plays a role in dermatological studies to test skin irritation and the biocompatibility of materials intended for prolonged skin contact.
