What type of products can be considered formulations?

Formulations refer to mixtures designed to produce specific properties or functionalities, and they can encompass a wide range of products. The correct choice highlights that formulations are not limited to just one category of products; instead, they can include a variety of products such as paints, cleaning agents, cosmetics, and pharmaceuticals, among others. Each formulation is carefully designed to ensure that all components work effectively together, enhancing performance for the intended purpose.

For example, in the case of paints, a formulation will include pigments, resins, solvents, and additives that collectively result in a product with the desired color, durability, and finish. Similarly, cleaning agents are formulated to maximize their ability to remove dirt and stains, often incorporating surfactants, solvents, and other ingredients to improve efficiency and user experience.

Other options suggest limitations on the kinds of products that can be classified as formulations, which does not accurately reflect the broad applicability of the term in everyday products across different sectors.
