Adding antioxidants to cosmetics is to enhance their health benefits and reduce the damage of free radicals to the skin. When the skin is exposed to external environmental factors such as ultraviolet radiation and pollutants, antioxidants in cosmetics can help the skin resist the damage of free radicals and maintain skin health. Meanwhile, antioxidants can also enhance the stability of cosmetics, making them more durable.
The metal ions that may be carried in cosmetics, especially heavy metal ions, have multiple impacts on product quality. To avoid these potential issues and ensure the stability of cosmetics, appropriate chelating agents need to be added when metal ions are present in the formulation system to chelate these metal ions.
