The global climate crisis demands that cosmetic science formulators evolve their toolbox and expand their expertise beyond traditional fields. While formulators already possess extensive knowledge in chemistry, biology, physics, and engineering, there is an urgent need to incorporate ecology, environmental science, and systems thinking. This paper presents the
“12 Principles of Green Formulation,” an adaptation of the influential “12 Principles of Green Chemistry” by John Warner and Paul Anastas, tailored specifically for cosmetic science formulation. These principles provide a practical guide for formulators to create inherently greener and more sustainable products. By applying these principles, formulators can select superior raw materials, streamline formulas, enhance product safety and efficacy, reduce production issues and waste, and promote a circular economy. This article details each principle and provides a condensed poster or sticker version suitable for quick reference, empowering formulators to contribute meaningfully to a more sustainable future in their daily work.
