How does your moisturizer feel when you apply it to your skin? Does it feel thick or thin, does it absorb quickly or does it stay on your skin? How your moisturizer feels is an intrinsic property the formulation, a careful selection of ingredients that interact with each other to make your moisturizer unique.
In collaboration with the Swedish skincare company ACO, RISE has, with the help of an experienced panel, quantified experiences linked to the application and the resulting “skin feel” of different moisturizers with specific ingredients. To understand how the properties of the moisturizers affect the experience during use, we measured physical properties such as the texture and microstructure of the formulation as well as the skin friction after application.
The results of the study, which is now summarized in a scientific publication, showed a connection between specific sensory experiences, physical properties, and different ingredients. Thickeners in the moisturizer affected the intensity of the sensory experiences when applied, while softeners in the moisturizer affected the skin feel. The skin friction has a strong connection with the after-feeling, while the consistency t affects the experience upon absorption and application to the skin.
Through the use of statistical analytics tools to analyze the relationship between perception experiences and physical characteristics, it is possible to find models that can predict the experience of a product based only on parameters determined by means of different instrumental measurements. This saves time and money when testing new ingredients during the development of the newly formulated products; the need for costly and time-consuming sensory testing with focus groups can be reduced and delayed.
– At RISE, we work with many different types of problems linked to formulation, perception and the connections between them, within different industries and product categories. Among other things, we have examined how different coatings affect the experience of a piece of furniture, how different foods feel in the mouth and how this differs between young and old. Helping companies better understand how they can control and predict perception experiences is really an exciting area and we are always open to new projects in perception and formulation, says Lisa Skedung, project manager at RISE.
