This week, I'm going to present to you some of the most common chemical structures in cosmetics. The point of this series is to prep you for my upcoming spring e-course (sign up HERE to be alerted to updates!) If you haven't taken organic chemistry yet, you may not be familiar with all of the chemical nomenclature of the different ingredients on a label. Thus, I decided to put this series of blog posts together to define some of these definitions and make understanding cosmetic chemistry a smoother transition. If you've already taken organic chemistry, you should be able to recognize most of these structures.
