What are common examples of formulations?

Common examples of formulations include paints, medicines, cleaning products, fuels, alloys, and cosmetics.

Formulations are mixtures that have been designed as a useful product. They are composed of several different components, each of which contributes a specific characteristic to the overall product. For instance, paint is a formulation that includes a pigment for colour, a binder to hold the pigment in place once the paint is applied, and a solvent to thin the paint so it can be spread easily.

Medicines are another example of formulations. They often contain an active ingredient that provides the therapeutic effect, along with other substances like binders, fillers, and coatings that help deliver the active ingredient effectively and safely. For example, tablets might include a coating to make them easier to swallow, or a slow-release mechanism to deliver the medicine over time.

Cleaning products are also formulations. They typically contain an active ingredient that does the cleaning, along with other ingredients that improve the product's effectiveness, such as surfactants that help it spread and cover the surface being cleaned, or fragrances that leave a pleasant smell.

Fuels like petrol or diesel are formulations too. They are mixtures of different hydrocarbons, each of which burns in a slightly different way. The exact composition of the fuel can be adjusted to give the best performance for a particular type of engine.

Alloys are metallic formulations. They are mixtures of different metals, designed to have properties that are better than any single metal alone. For example, steel is an alloy of iron and carbon that is stronger than pure iron.

Finally, cosmetics like lipstick or mascara are formulations. They contain a variety of ingredients, including pigments for colour, waxes for structure, and oils for smooth application. Each ingredient contributes to the final product's performance, appearance, and feel.
