Chemical stability refers to the ability of a substance to maintain its chemical composition and properties over time, when exposed to various external factors such as temperature, light, air, and moisture. Understanding the chemical stability of a substance is important in various industries, including pharmaceuticals, food and beverages, and cosmetics, as it can impact the quality, safety, and shelf-life of products. Research in chemical stability involves studying the degradation mechanisms of substances, identifying factors that influence stability, and developing strategies to improve stability and extend product shelf-life. This research area is crucial for ensuring the effectiveness and safety of products, as well as reducing waste and improving sustainability in various industries.
