Characterization of the Interactions between Polymethacrylate‐Based Aqueous Polymeric Dispersions and Aluminum Lakes
Instability in film coating formulations can arise from interactions between aluminum lake pigments and aqueous polymeric dispersions. The purpose of this study was to characterize the interactions between three polymethacrylate‐based aqueous polymeric dispersions (Eudragit® RS 30 D, Eudragit® L 30 D‐55, and Eudragit® NE 30 D) and aluminum lakes.

Mixing Matters: The Key Process Behind Every Great Product
Mixing is probably the single most common processing step across almost all manufacturing industries. The related term blending is often used interchangeably, though it usually applies to the mixing of solids such as powders. At Innovating Sciences we focus especially on Food, Beverage, Personal Care, Cosmetic and Pharmaceutical industries but mixing principles are used in many other diverse fields. These include Agriculture (e.g., livestock feeds, compound fertilizers), Chemical Engineering, Construction (e.g., mixing of concrete), Detergents, Paints, Coatings and Energy (e.g., oil and gas refining).
