An Isotonic Solution creates a mild, less concentrated salt solution of 9mg of Sodium Chloride per mL of water, which has a similar salt concentration as your body and may be more comfortable to use for some people initially compated to the more concentrated Hypertonic solution.
Video: Hypotonic vs. hypertonic: A hypertonic solution (pronounced HÄª-per-TAWN-ik) is a solution with a higher concentration of solute (dissolved substance) than some other, specified solution (and which therefore has a higher osmotic pressure than the other solution). The solution with the lower concentration is then termed hypotonic.
