Abstract: Optimizing the sensory properties of o/w emulsion systems is an ongoing challenge for formulators, thus tools to simplify this process are desirable. Here, the authors describe a visual tool to assist in selecting the right combination of certain crosslinked acrylic rheology modifiers and specialty emollient esters to meet target aesthetics.

Optimization of the sensory properties in emulsion systems is an ongoing challenge for formulators. Here, the authors present a tool designed to simplify the process. This visual tool called SensiMap assists formulators in selecting the right combination of specific crosslinked acrylic rheology modifiers and specialty emollient esters to match the desired formulation aesthetic profile. Rheology modifiers impact the texture element of sensory, particularly during the initial application (rub out) and emollient esters enhance sensory through to after feel.
