Analytical methodIn vitro PRINCIPLE The in vitro method is based on measuring the residual transmission spectrum through a layer of product applied to specific substrates. This assessment is carried out using a spectrophotometric technique, which quantifies the amount of UV radiation that passes through the product, in order to estimate its effectiveness in blocking UV (UVB and UVA). &nbsp; &nbsp; Standards ISO 23675:2024: Cosmetics &#8211; Sun protection test methods &#8211; In vitro determination of sun protection factor (SPF) ISO 24443:2021: Cosmetics &#8211; In vitro determination of UVA photoprotection FDA 2021 : U.S. Food and Drug Administration &#8211; Final Administrative Order (OTC000006) &#8211; Over-the-Counter Monograph M020: Sunscreen Drug Products for Over-the-Counter Human Use Boots Star Rating System 2011: Measurement of UVA:UVB ratios No ethical problem (non-human model), Measuring [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"class_list":["post-10295","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/weneos.com\/en\/wp-json\/wp\/v2\/pages\/10295","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/weneos.com\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/weneos.com\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/weneos.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/weneos.com\/en\/wp-json\/wp\/v2\/comments?post=10295"}],"version-history":[{"count":21,"href":"https:\/\/weneos.com\/en\/wp-json\/wp\/v2\/pages\/10295\/revisions"}],"predecessor-version":[{"id":13365,"href":"https:\/\/weneos.com\/en\/wp-json\/wp\/v2\/pages\/10295\/revisions\/13365"}],"wp:attachment":[{"href":"https:\/\/weneos.com\/en\/wp-json\/wp\/v2\/media?parent=10295"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
