A cosmetic solution that contains a small quantity of solute in relation to the solvent is referred to as what?

A cosmetic solution described as containing a small quantity of solute in relation to the solvent is characterized as dilute. In this context, "dilute" specifically refers to a mixture where the concentration of the solute is low compared to the solvent. This is an important concept in both chemistry and cosmetic formulations, as the concentration of active ingredients can significantly affect the performance, safety, and texture of products.

Using a dilute solution in cosmetic formulations can enhance the gentleness of the product, making it suitable for sensitive skin types. It also allows for better mixing and incorporation of active ingredients, which can be critical when developing products like toners, serums, and moisturizers that aim to provide hydration and nourishment without overwhelming the skin with potent substances.

By understanding the nature of a dilute solution, estheticians can make informed decisions about product applications and formulations, ensuring that clients receive safe and effective treatments.
