According to Cliff & Linda Hoyt “Rubifoam for the Teeth was sold by E. W. Hoyt & Co. (The name is pronounced like Ruby Foam due to the brilliant red color of the product.) It was introduced in 1887, the same year that E.W. Hoyt died at the age of 49. In addition to trade cards the company also published a number of pamphlets for Rubifoam. The pamphlets typically were providing information on taking care of your teeth.” The E. W. Hoyt & Co. was also well known for producing Hoyt’s German Cologne, which the firm widely advertised with Rubifoam in many decorative and often colorful trade cards, pamphlets and magazines ads.
Archaeologist John Parker writes, “Hoyt’s German Cologne was introduced in 1870 by E.W. Hoyt. Hoyt began working at E. A. Staniels’ apothecary shop in Lowell, MA in 1851, at the age 13. When Staniels died in 1861, Hoyt took over the business. He developed the cologne at the shop but by 1877 the cologne business had grown so large that he sold the old shop to concentrate on the cologne business. His partner Freeman B. Shedd was the marketing wizard behind the product. Hoyt died in 1887, the same year Shedd brought out Hoyt’s “Rubifoam” tooth wash.”
Marshall Clark, at the Kansas Historical Foundation, notes in his description of Fort Hays archaeological finds from the 1870s that “‘Brushing the teeth, though in vogue in foreign armies and approved by hygienists as a preventative of agues and diseases, was rare,’ states George W. Adams in his fascinating book, titled Doctors in Blue. The archaeological collection contains a number of toothbrush handle remnants. They are made from ivory, bone, or celluloid, and one is inscribed ‘Ivory Finish.’ Several include remains of the bristles. Bottles in this collection represent at least three different brands of tooth cleaners. Back then, these preparations were called “tooth washes.” One brand, ‘Rubifoam for the Teeth,’ was made by E. W. Hoyt and Company of Lowell, Massachusetts. Rubifoam cost twenty five cents a bottle and was described as being “deliciously flavored.” The company even put out a small publication promoting the prevention of tooth decay through the use of its product. It was much later, in 1901, that the idea that bacteria caused decay was accepted.”
