Solvent

A solvent in cosmetics is a substance, often water, alcohol, or glycol, used to dissolve, suspend, or disperse other ingredients—such as pigments, oils, and active compounds—to form a smooth, uniform solution. Their essential function is to ensure a product’s consistent texture, control its viscosity, and facilitate the effective delivery and absorption of key ingredients into the skin or hair. By allowing unlike ingredients to blend seamlessly, they are indispensable for creating stable and aesthetically pleasing formulations across all cosmetic categories.
