| titleOfInvention | Method for determining an integrated solar protection factor wrapping UVA and UVB radiation |
| abstract | The present invention relates to a method for determining an integrated solar protection factor (SPF or iSPF) that encompasses both UVA and UVB radiation that can be used to classify cosmetic and dermatological sunscreens. The method comprises the steps of applying a defined amount of sunscreen to a defined area of skin impregnated with a spin trap; and applying the defined amount of UVA and UVB rays to the skin substrate with a solar simulator. Exposing the skin substrate exposed to the radiation to electron spin resonance (ESR) measurement; real number × 10 12 free radicals / 1 mg of skin sample, the number of trapped free radicals Recording; and determining an integrated solar protection factor SPF according to equations (1), (2) and (8): SPF = E 0 / E (1) log 10 (E) = alog 10 (X · 1000) + b (2) E = 10 log10 (E) (8) [Selection figure] None |
