1940s–1960s
In 1947 the business was resurrected, and registered in the State of New York under the name the Stiefel Medicinal Soap Company, Inc., initially operating from a former creamery in Oak Hill, New York. As the product line grew and diversified beyond medicinal soaps, the company was renamed Stiefel Laboratories, Inc.[7]
In 1948, the Stiefel Medicinal Soap Company worked with dermatologists to develop the Oilatum family of products, which treat dry skin and atopic dermatitis.[7]
In 1959, Zeasorb has the ability to absorb six times its weight in moisture. Stiefel developed Zeasorb products with dermatologists, who identified the need for such a powder.
Introduced in 1960, Polytar first featured the combination of tars in a shampoo.[7]
In 1966, Stiefel introduced the first benzoyl peroxide product for acne—Sulfoxyl Lotion (5% benzoyl peroxide, 2% sulfur). The treatment was introduced to Canadian dermatologists as BenOxyl Lotion.[7]
As the Stiefel Medicinal Soap Company's product line grew and diversified beyond medicinal soaps, the company name was changed to Stiefel Laboratories, Inc. At that time, all production was done at the Oak Hill, New York, facility. Eventually its network of distributors, subsidiaries and manufacturing facilities in other countries allowed the company to manufacture and distribute products around the globe. During the 1960s, sales and manufacturing operations expanded to include Canada, Puerto Rico, Germany, Hong Kong, the United Kingdom, Costa Rica, the Philippines, Ireland and other locations. By 1969, non-US international sales had reached $200,000.
