Cosmetic Formulation Science

About this course

This course is part of the Cosmetic Science Specialization. This course explores the science and practice of cosmetic formulation, guiding you from foundational raw material selection to advanced product optimization and performance evaluation. You will examine surfactants, emulsifiers, preservatives, rheology modifiers, and additives, while developing safe and effective laboratory practices, accurate documentation, and quantitative formulation skills. As the course progresses, you will apply formulation mathematics, interpret Certificates of Analysis, and compare skincare system designs to support stable, high-performing products. In the final module, you will integrate testing data, troubleshoot formulation challenges, and justify product design decisions using real-world scenarios. By the end of the course, you will be prepared to design, evaluate, and refine cosmetic formulations with scientific rigor and professional confidence.
