Particularly, provided are methods of measuring the harshness of a surfactant, which includes (a) providing an aqueous solution of surfactant and taking a first colour measurement; (b) adding a solid protein-dye complex to the aqueous solution of surfactant; (c) taking a second colour measurement and measuring the change in colour between the first colour measurement and the second colour measurement; and (d) matching the change in colour with a reference scale. The solid protein-dye complex can be prepared by dissolving a non-denatured corn protein and a protein binding dye in aqueous alcohol, and removing the aqueous alcohol."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of measuring harshness of a surfactant","description":"Provided is a quick and accurate way of assessing harshness of a surfactant towards a protein, which can be easily carried out under non-laboratory conditions and which facilitates recommendations for","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11486880","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.
