How to Use GOHSENOL™

Storage of Aqueous Solutions

  • An aqueous solution of N- or A-type GOHSENOL™ usually increases viscosity or causes gelation when left alone. A lower temperature and higher saponification degree will make this tendency more remarkable. If the aqueous solution contains GOHSENOL™ alone, it usually returns to its former state when the temperature is raised.
  • G- or K-type GOHSENOL™ is less likely to gelate than N- and A-type (hardly gelate even at a higher concentration). Sorbic acid, rhodan salt, or a higher alcohol is effective for preventing gelation if it is slight.
  • Do not use containers that easily rust. Sodium nitrite or sodium benzoate is effective for the prevention of rust.
  • Mildew rarely grows in aqueous solutions of GOHSENOL™.
  • Sodium dehydroacetate, potassium sorbate, and sodium pentachlorophenol effective preservatives (0.01-0.1 weight % to an aqueous solution of GOHSENOL™ is suitable).
  • In the case of adding rust inhibitors or preservatives, be sure to refer to the instruction manuals provided for the chemicals.
