  • Patent number: 8598535
    Abstract: An evaluation method for evaluating the ultraviolet protection effect of a measurement sample applied on a substrate includes measuring, at predetermined wavelength intervals, a change over time of a spectral transmission spectrum of the measurement sample within a predetermined wavelength range by irradiating light from a light source that includes ultraviolet light, visible light, and infrared light under a predetermined irradiation condition; establishing, based on the change over time of the spectral transmission spectrum, a correlation between a light irradiation time and an erythema effective dose per unit time, which is obtained by dividing an erythema effective dose of the measurement sample by an erythema effective dose per 1 MED; and calculating an in vitro rSPF predictive value for the measurement sample on the basis of a time until a cumulative erythema effective dose, which is obtained through time integration based on the correlation, reaches 1 MED.

  • Patent number: 7937227
    Abstract: A method and apparatus for evaluating an ultraviolet radiation protection effect in a measurement sample is used for evaluating SPF (Sun Protection Factor). First, a temporal change of the spectral transmission spectrum in the measurement sample within a predetermined light wavelength range at predetermined wavelength intervals is measured. Second, a correlation between a light irradiating time and minimal erythema doses by predetermined lime intervals based on the temporal change of the spectral transmission spectrum is set. Third a predicted in vitro SPF in the measurement sample using a time until an accumulated minimal erythema dose that is obtained as a time integration of the minimal erythema doses based on the correlation obtained in the second step reaches 1 MED (Minimum Erythema Dose) is calculated.
