Which of the following best defines a solvent?

A solvent is best defined as a substance that dissolves other ingredients. This definition captures the essential role of a solvent in various chemical processes, especially in cosmetology and beauty products. Solvents are typically liquids capable of dissolving solid, liquid, or gaseous solutes, resulting in a solution. In many formulations, solvents are crucial for ensuring that active ingredients are effectively dispersed, allowing for better application and efficacy of products like creams, serums, and disinfectants.

By utilizing solvents, cosmetologists can achieve the desired consistency and stability of products, as well as enhance the absorption of other ingredients into the skin or hair. Understanding the function of solvents is fundamental for anyone working in the field, as it allows for better formulation practices and product knowledge.
