Abstract

Several different emollients were investigated to understand the correlation between their structure and their sensory properties. Furthermore, the emollients were also compared with synthetic mineral oils in order to have a complete overview of emollients. In this study, we will show you how to choose the proper emollients in order to achieve the desired sophisticated sensory effect in your skin care or make-up product. Let yourself be inspired by emollients and follow your own rhythm and creativity when designing your own formulation playlist.
