Nanoemulsions and green ingredients are the focus of a recent paper published in the Journal of Surfactants and Detergents. Here, the authors reviewed skin-friendly emulsifiers sourced from plants or microbes and their potential to replace synthetic ingredients.
According to the authors, the well-known link made by consumers between health benefits and natural ingredients has prompted the search for greener ingredients that are benign to the skin and effective in formulations. Here, they sought to identify possible alternatives based on parameters crucial to stable emulsions, including:
- Critical micelle concentration (CMC);
- Hydrophilic/lipophilic balance;
- Critical packing parameter; and
- Winsor ratio.
