What combination of solvents is typical for elixirs to dissolve both water-soluble and alcohol-soluble components?

• A. A mixture of water and alcohol
• B. Only water
• C. Only ethanol
• D. Only glycerin

Answer: (A)

Elixirs are designed as solvent systems that cover a range of solubility, so they need solvents with different polarities. Water is highly polar and dissolves many hydrophilic substances, while alcohol (ethanol) has intermediate polarity and can dissolve many compounds that water alone cannot, including flavoring oils and some active ingredients. By using a mixture of water and alcohol, the liquid can dissolve both water-soluble and alcohol-soluble components in a single solution.

Relying on water alone would leave alcohol-soluble ingredients poorly dissolved. Using only ethanol would struggle with more polar, water-loving substances and would also affect palatability. Glycerin can act as a humectant and sweetener and is sometimes included, but on its own it doesn’t provide the broad solvation needed for a wide range of solutes. Combining water, alcohol, and sometimes glycerin gives a flexible, palatable solvent system that can handle diverse components.

So, the typical solvent for elixirs that dissolves both water-soluble and alcohol-soluble components is a mixture of water and alcohol.
