A formulation scientist designs, develops, tests, and evaluates products. Their job duties involve blending and mixing chemical components to create effective products, often for the pharmaceutical or cosmetics industries. Formulation scientists play an integral role in the product development process by implementing testing procedures, inspecting manufacturing approaches, and creating detailed reports to fix errors and promote improvements. To become a formulation scientist, you need a bachelor’s degree in chemistry or a related field, although many also pursue master’s degrees or a doctorate.
