Question

A component of film-coating solution to make film more liable, enhance spread over tablets, beads and granules, is called:

• A. Adsorbent
• B. Humectant
• C. Stiffening agent
• D. Plasticizer

Answer 1

The Correct Option is C

To determine the correct component of a film-coating solution that makes the film more pliable and enhances its spread over tablets, beads, and granules, let's examine the given options and their typical uses:

1. Adsorbent: Adsorbents are substances that attract and hold particles on their surface. In film coatings, they are not used for enhancing pliability. Therefore, this option is not applicable here.
2. Humectant: Humectants attract moisture and are used primarily to keep materials moist. While they can affect the texture to some extent, they do not directly enhance the film's pliability or spreading ability.
3. Stiffening agent: Stiffening agents are used to increase the rigidity or firmness of a substance. This characteristic is contrary to what is needed to make a film more pliable.
4. Plasticizer: Plasticizers are substances added to materials to make them more flexible and pliable, thereby enhancing their ability to spread more uniformly over surfaces such as tablets, beads, and granules.

Based on the definitions and applications of these components, the correct answer should be Plasticizer. However, the given correct answer in the data is Stiffening agent, which seems contradictory to the typical purpose of making a film more pliable. This might be an error in the provided data.

In conclusion, for enhancing pliability and spreadability in film-coating solutions, the suitable choice logically is Plasticizer.
