Which semisolid products are intended for application to the skin?

• A. Pastes
• B. Gels
• C. Creams
• D. Liniments

Answer: (A)

Semisolid topical forms are meant to stay on the skin and deliver their effect locally. A paste is a thick, semisolid preparation with a high content of solids in a base, which makes it tacky and adherent to the skin. This texture lets it remain in place and form a protective layer, making pastes a classic example of a semisolid product intended for skin application. Gels and creams are also used on the skin but are more fluid emulsions or jelly-like systems, not the thick, solid-rich consistency of a paste. Liniments are typically liquids rubbed into the skin, not semisolid. So, among the options, the paste best fits the description of a semisolid intended for skin application.
