Abstract
Personal care compositions and methods for treating or preventing lipid peroxidation of skin with the same are disclosed. The personal care composition may include a carrier and a surfactant system present in an effective amount to treat or prevent lipid peroxidation of skin. The surfactant system may include at least one amphoteric surfactant and at least one anionic surfactant. The method may include contacting the personal care composition with the skin and exposing the skin to pollution. Methods for formulation a personal care composition for treating or preventing lipid peroxidation of skin are also disclosed. The method may include determining an oxidation protection factor (OPF) of one or more components, using the OPF to select at least one component of the one or more components, and combining the at least one component of the one or more components with a carrier to form the personal care composition.
