# Resinol

Resinol is a skin protectant and topical analgesic that is made by ResiCal Inc. from Orchard Park, New York. It is an over-the-counter drug that can currently be purchased in 1.25 or 3.3 ounce (35 or 94 g) jars by contacting a local pharmacy's drug wholesaler to order the item or on the Internet. It is an ointment that is beige in color and has a distinctive rubbery scent. It has a tacky consistency and is somewhat difficult to get off undesired body parts it comes into contact with (like one’s fingers after applying it).

## History

Resinol was developed by Dr. Merville Hamilton Carter (1857-1939) in his private practice as treatment for his patients in Baltimore, Maryland during the late 19th century. In 1895, Carter, along with his brother Allan L. Carter and his cousin Henry Stier Dulaney founded the Resinol Chemical Company and began to mass-produce the ointment and other medical products. After over forty years of selling Resinol, the company had John H. Buffham & Co. as an outlet in Great Britain and was a successful global distributor. Henry LeRoy Carter Sr., the son of Dr. Carter, began running the company after the deaths of his father and other staff members. The company's sales began to decline in the 1940s, and after the death of Henry LeRoy Carter Sr. in 1951, his son Henry LeRoy Carter Jr. took the place of his father and grandfather as president of the Resinol Chemical Company. At that time, the company focused more on soap manufacturing, but continued to sell Resinol. For the rest of the 20th century, Resinol's popularity continued to dwindle. It was purchased by ResiCal Inc. in 2002, which at the time was headed by D. Brooks Cole.
