The indicator is zincon or a salt thereof. The method is useful for estimating the ability of an oral care composition to deliver therapeutically-active zinc (II) ions to the oral cavity. Also provided is the use of zincon and a biorelevant substrate in vitro to determine the bioavailability of zinc (II) ions from an oral care composition comprising, a zinc source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Determining the bioavailability of zinc (II) ions","description":"An in vitro method for determining the bioavailability of zinc (II) ions from an oral care composition comprises: providing a sample comprising, the oral care composition; contacting the sample with a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9625449","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.
