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.
Hypertonic Definition. HYPERTONIC solution: has higher concentration of solute than the cell, water diffuses out and the cell shrivels HYPOTONIC solution: has a lower concentration of solute than the cell causing water to diffuse into the cell. The cell will swell and could burst. ISOTONIC solution: has the same concentration of solute as the cell so water diffuses in and out evenly
