Which dehydrants dehydrate more rapidly at 20°C, low viscosity or high viscosity?

Explanation:
When a dehydrant works at a constant temperature, how quickly it removes water from tissue is largely tied to how easily its molecules can move and diffuse into the tissue. Lower viscosity means the liquid is thinner, so its molecules can flow and migrate more readily. This increases the diffusion coefficient, allowing the solvent to penetrate the tissue and replace water more quickly. As a result, dehydration proceeds faster. Higher viscosity solvents move more slowly, hindering diffusion and delaying water removal, so dehydration is slower. At 20°C, the solvent with lower viscosity will thus dehydrate more rapidly.
