This is a Vanilla product that was only for sale within The Upjohn Company. Don Parfet told me that Dorothy Dalton, a daughter of W.E.Upjohn, used a lot of vanilla in her cooking but could not find a good quality source of it in Kalamazoo. Since The Upjohn Company already used large quantities of vanilla flavoring in products like Kaopectate, the materials were already in-house. It didn’t take much effort to formulate and bottle it. Calling it Imitation Vanilla is a misleading. It was a vanilla extract with a small amount of added vanillin.  It was a popular product with employees because batches were made through the 1970s and 80s. It was discontinued in 1989. Other products made for employees-only were Hand Lotion and Aspirin Tablets 5gr.
