Assessment of the Sunscreen Properties of Sesame Oil Using the Hemispherical Directional Reflectance Method

Abstract

Sesame oil has been widely used for centuries. It is not only used as a kitchen ingredient, but it is also used to apply to the skin. Sesame oil contains natural compounds such as sesamol, sesamolin and sesamide, which have the ability to reflect or absorb certain UV rays. These substances can act as UV filters, helping to minimize the effects of harmful UV radiation on the skin. The aim of the study was to investigate the radioprotective/sun protection properties of sesame oil. The influence of sesame oils from different manufacturers on the directional reflectance of the skin was analyzed at various time intervals. To assess the sunscreen properties of the oil, a new technique was used: the 410-Solar hemispherical directional reflectometer. Sesame oil can be used in sunscreen preparations, but only when combined with other, more powerful ingredients. The oil itself is not sufficient protection against solar radiation. The study revealed no significant disparities in performance between the tested sesame oils from diverse manufacturers.
