Creating the right sensory characteristics

 It will also attempt to correlate the rheological properties to skin sensory attributes. By linking and understanding these properties, formulators can thus easily choose the best rheology modifiers for developing skin care formulations with the right sensory attributes that positively influence the consumers’ perceptions.

Formulations can be tailored to the desired emotive and sensory signals required by consumers to create distinctive consumer product use experiences. Careful design of the sensory properties of a formulation can transform a skin care routine for a consumer into a pleasant, memorable experience that fosters product loyalty and encourages repeat use. Formulating cosmetics to deliver precisely the right feel at exactly the right stage during application to meet specific consumer sensory preferences is more important than ever. That is why recent innovations and studies focus more and more on optimising sensory characteristics of products. There are several ways to optimise sensory attributes of cosmetic formulations. But many formulators do not consider rheology modifiers as a primary option to achieve this goal. Typically, rheology modifiers come to mind only when there is a need for increasing viscosity. Moran1 previously described that the sensory profile of an oil-in-water emulsion can be optimised by intertwining complementary sensory cues from two seemingly unrelated technologies: water dispersible rheology modifiers to impact the texture element of sensory during initial application, and ester emollients to enhance sensory from rub-out through after-feel. This paper will demonstrate how various crosslinked acrylate-based rheology modifiers can affect the sensory attributes of skin care products and how the rheological and inherent properties of these polymers can describe, and even predict, sensory attributes.
