Skin benefits

  • Chitosan-based polymer that forms a soft, conditioning film on skin and hair

Known concerns

  • No CAS number or public toxicology dossier was located for this specific derivative
  • Chitosan is usually sourced from crustacean shells, so it is not vegan and may concern shellfish-allergic users
  • Sulfonate modification means strict residual monomer and pH controls are needed at the supplier
  • Complex three-part modification can vary between batches and manufacturers
