mixes

Mixes are substances formed by combining two or more components in which the components retain distinct identities. In common usage, mixtures differ from compounds by lacking a fixed chemical bond between components. Mixtures can be homogeneous, with a uniform composition, or heterogeneous, with visible separations of phases.

The process of forming a mixture is mixing or blending and can be achieved by stirring, shaking, whisking, blending, or more advanced methods such as homogenization and emulsification. Techniques vary with viscosity, particle size, and phase behavior, and some mixtures are physically reversible.

Applications span many fields. In food and beverage, dry mixes and batters provide convenient, shelf-stable ingredients; spice blends create consistent flavors; emulsions such as vinaigrettes are common. In paints, coatings, and cosmetics, pigments are dispersed to form stable suspensions. In construction and manufacturing, premixes and blends form concrete, alloys, or polymer composites. In pharmaceuticals, premixes help ensure uniform distribution of active ingredients and excipients. In music and audio, a mix refers to the combination of individual tracks into a final recording, with adjustments to level, tone, and spatial placement.

Quality and safety concerns focus on achieving homogeneity and preventing segregation or clumping. Uniform mixing is essential for consistent performance, while over-mixing can damage certain materials or alter textures. Methods and equipment are chosen to suit the material properties and the desired end use.
