Chemical History Timelines

A screen capture of a colorful timeline.

In 2018, members of the Chemical Entanglements Undergraduate Student Group researched and created interactive timelines that outline the history of synthetic chemicals, particular fragrances, essential oil usage, and their links to women’s health and activism.

We invite you to explore these timelines and learn from our student research!

Screen-reader-friendly, text-only versions of the timelines are forthcoming.

The mass production of essential oils has, therefore, heavily relied on various methods to accelerate and cheapen the process. What are we paying for when we buy essential oils, and what is known about the safety of these products? What does history reveal about the safety and regulation of cosmetic products, such as essential oils?
