Abstract: This article describes the mechanisms of acrylate and polyurethane copolymers used as rheology modifiers. It gives examples of their use, and suggests new uses in emulsification and in suspending particles in clear formulations.

Formulators of personal care products must meet the ever-increasing expectations of the consumer, In order to develop products that possess excellent appearance, feel and flow characteristics while exhibiting superior performance and functionality, formulation chemists look to specialty ingredients to gain competitive advantage. The featrues and benefits of synthetic copolymers make them attractive candidates as specialty ingredients for personalc care formulations.

Synthetic copolymers are typically available in aqueous solutions. As liquids, they can be directly incorporated into a formulation without any preparation (warming, declumping, dissolving,e tc.), allowing for cold processing, and avoiding the concerns often associated with powders (dustiness, hygroscopic nature, etc.).
