Lotion Making Science

Lotions, Creams, and Other Emulsions

In this beginning-through-advanced Lotion Making Science class, take a scientific, hands-on approach to learning different methods and techniques for making lotion. Students learn to make small, test batches of lotion and how to increase the recipe to make larger batches. Gain confidence by learning how a batch of lotion that has separated or gone wrong can always be salvaged. Understand the importance of emulsifiers and emulsification systems: what they are and how they work. Perform scientific test experiments to prove whether or not common lotion ingredients (such as lecithin, polysorbate, and stearic acid) act as emulsifiers. In this Lotion Making Science class, students compare four (4) different emulsifiers in performance challenges to determine which emulsifiers cause soaping (white streaks during application), which emulsifiers are better for the face (non-comedogenic), which emulsifiers are water miscible (and better for use in hair conditioner), and which emulsifiers are considered natural ingredients (and widely accepted by modern consumers). This class also briefly covers labeling requirements, preservatives, and professional lab testing. Students make lotion in class and receive four (4) different lotions to take home.
