class=\"gch-faq\">\r\n      <details open>\r\n        <summary>What is Chitosan?<\/summary>\r\n        <p>Chitosan is a deacetylated chitin polysaccharide made mainly of D-glucosamine and N-acetyl-D-glucosamine units. In supplement raw material sourcing, it is evaluated by source, DDA, viscosity, molecular weight range, particle size, moisture, heavy metals, microbiology and batch COA.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>What is the CAS number of Chitosan?<\/summary>\r\n        <p>The CAS number commonly used for Chitosan is 9012-76-4. Buyers should confirm identity, source, DDA, viscosity and specification by supplier documents and batch COA.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Is Chitosan a single molecule?<\/summary>\r\n        <p>No. Chitosan is a polymeric material, so molecular weight is usually expressed as a range or described by viscosity and degree of polymerization rather than one fixed molecular weight.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>What is degree of deacetylation in Chitosan?<\/summary>\r\n        <p>Degree of deacetylation, or DDA, describes the percentage of deacetylated glucosamine units in chitosan. It is a key quality parameter because it affects charge density, solubility behavior and application performance.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Is Chitosan water soluble?<\/summary>\r\n        <p>Standard Chitosan is generally not soluble in neutral water but is soluble in dilute acidic solutions. Chitosan HCl is a separate water-soluble form and should be reviewed as a different specification.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>What is the difference between Chitosan and Chitin?<\/summary>\r\n        <p>Chitin is the natural polysaccharide found in crustacean shells and other biological sources. Chitosan is produced by deacetylating chitin, which increases free amino groups and changes solubility and charge behavior.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>What is the difference between Chitosan and Chitosan HCl?<\/summary>\r\n        <p>Chitosan is the standard deacetylated chitin polymer, while Chitosan HCl is a hydrochloride salt form designed for better water solubility. They should be sourced, specified and labeled separately.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Is Chitosan shellfish derived?<\/summary>\r\n        <p>Commercial Chitosan is commonly derived from shrimp or crab shell chitin. Buyers should request source declaration, species information, allergen statement and cross-contact information before label use.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Is Chitosan vegan?<\/summary>\r\n        <p>Traditional Chitosan is usually crustacean shell-derived and is not vegan. Fungal or non-crustacean chitosan options should be requested separately and supported by supplier documentation.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Can Chitosan be used in capsules or tablets?<\/summary>\r\n        <p>Yes. Chitosan can be evaluated for capsules and tablets when serving size, DDA, viscosity, bulk density, flowability, particle size, compression behavior and stability are suitable.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Can Chitosan be used in drink powders?<\/summary>\r\n        <p>Standard Chitosan is not neutral-water soluble, so drink powder concepts should be tested for acid pH compatibility, dispersion, texture, sediment, taste and label positioning. Chitosan HCl may be reviewed when water solubility is required.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>What quality indicators should be checked?<\/summary>\r\n        <p>Buyers should review source, DDA, viscosity, molecular weight range, pH, loss on drying, ash, acid-insoluble matter, particle size, bulk density, heavy metals, microbiology, allergen status and batch COA.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>What documents can I request before ordering?<\/summary>\r\n        <p>Qualified B2B buyers can request COA, specification sheet, SDS, TDS, source declaration, allergen statement, non-GMO statement, residual chemical report, flow chart, stability information and other technical files depending on the selected grade.<\/p>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Does Gensei supply Chitosan for medical, pharmaceutical, cosmetic, animal feed or water treatment use?<\/summary>\r\n        <p>This page is focused on B2B dietary supplement ingredient sourcing.
