Which of the following is NOT a characteristic of a liniment?

Liniments are topical preparations used to relieve pain and stiffness in muscles and joints. They are typically applied to the skin and are formulated to penetrate the skin's surface to provide localized relief. One of the defining characteristics of liniments is that they often contain alcohol as a solvent, which helps in delivering the active ingredients effectively.

The presence of oil or soapy emollients also aligns with the formulation of liniments, as these ingredients enhance the product’s ability to soothe and hydrate the skin while delivering pain relief.

The key point is that liniments are designed for external use and are not intended to be ingested or digested. Therefore, the characteristic of being "typically digested" does not apply to liniments, making it the accurate answer to the question.
