Disodium Rutinyl Disulfate
What is Disodium Rutinyl Disulfate?
Disodium rutinyl disulfate is a semi-synthetic derivative of rutin, a flavonoid glycoside extracted from plant sources such as buckwheat and Sophora japonica flowers. Through sulfation, it gains high water solubility, overcoming rutin's natural insolubility, which allows incorporation into aqueous cosmetic bases like serums, creams, and eye treatments. Primarily categorized as an antioxidant agent, it operates by donating electrons to neutralize free radicals, thereby preventing lipid peroxidation in skin cells and product ingredients. This stabilization extends shelf life by slowing oxidation of oils and sensitive actives, while also aiding in maintaining product integrity against light and air exposure. In skincare, it appears in anti-aging and protective formulations, where its role supports overall product performance without altering texture significantly.
