Green, Purple, or Red? Developing Stable and Effective Color Concepts for Aqueous Personal Care Products with Natural Extracts

Creams, shower gels and bubble baths are often developed with a color concept to achieve a refreshing or relaxing effect or to emphasize certain ingredients. Natural extracts are particularly popular in natural cosmetics, but also come with challenges when used in aqueous products and their storage. With this study we propose a method to verify stability and to reconcile product efficacy and shelf life. We also highlight the advantages to not only work with coloring the product, but also pay attention to the design of the packages, especially with regards to colors and smart labelling, to support the appearance and message of the product.
