As a means for achieving the foregoing, an absorbance measurement method is provided, wherein an absorbent aqueous composition is applied on the surface of a substrate, which surface has been plasma treated, arc-discharge treated, or corona-discharge treated, to achieve a contact angle with pure water of 0 to 70.0 degrees, and the applied absorbent aqueous composition is measured for absorbance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for measuring absorbance of aqueous compositions using a substrate having a surface with an adjusted contact angle with water","description":"An object is to measure absorbance of aqueous cosmetic materials that have not heretofore been studied for absorbance measurement, and particularly to form a uniform layer of thin film in order to ens","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11525779","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
