Liquid formulations are mixtures where active ingredients are dissolved or suspended in a liquid medium. These formulations are commonly used in pharmaceuticals, cosmetics, and food products, allowing for easy application and absorption. The liquid state can enhance the bioavailability of the active components, making them more effective. In the pharmaceutical industry, liquid formulations can include solutions, suspensions, and emulsions. They are often preferred for patients who have difficulty swallowing solid forms like tablets or capsules. Additionally, liquid formulations can be tailored for specific delivery methods, such as injections or oral solutions, ensuring that the medication reaches the intended site of action efficiently.
