  • Evaluating the efficacy of leave-on cosmetic compositions to protect skin from pollutants
    Patent number: 11385181
    Abstract: Disclosed is a method of determining efficacy of a cosmetic composition to inhibit an atmospheric pollutant from contacting skin, comprising the steps of: (i) filling a sample holder of known dimensions with known amount of said composition to form a layer of defined thickness therein, where said sample holder is amenable to fluorescence-based assay; (ii) depositing, on said layer, a known amount of a model fine particulate matter which resembles an atmospheric pollutant at least in size and which comprises a material responsive to fluorescence microscopy which is excitable by a wavelength (?ex) and which emits radiation (?em) where (?ex)?(?em); (iii) irradiating said composition and said model fine particulate matter by said ?ex and recording intensity of fluorescence at ?em a plurality of times for a defined period during which said model fine particulate matter interacts with said layer; and, (iv) determining, corrected intensity of fluorescence at ?em by the following equation; corrected Intensity=recorde
