Historical Context

Tween-20, also known as Polysorbate 20, is a non-ionic surfactant and emulsifier often used in pharmaceutical and laboratory settings. The label indicates it was produced by the Atlas Power Co. (later known as Atlas Chemical Industries), which was a major developer of these chemicals in the mid-20th century. The amber glass and black screw cap are characteristic of medicine bottles from the 1930s
