H&S Chemical Co. Inc. was formed August 30, 1983 by Dr. Charles A. Schneider. The Company initially started as a 50/50 joint venture between HVC Chemical and Dr. Schneider. The business began operations on Murray Road in Cincinnati, Ohio. During the first few years, H&S developed business mainly by providing consulting services to larger companies. At about the same time, a small research laboratory was built where many of the products from the current line were started. During the middle to late 1980's, H&S researched and developed more than 35 specialty products and currently maintains a specialty line of disinfectants, FDA approved products and EPA registered products. In 1992 the remaining half of the business was purchased by Dr. Schneider who is now the sole owner of the company.

H&S is a technology-based company serving various industries with select specialty chemicals. The customer base ranges from very small private companies to the U.S. Military. The company has directed some of its efforts in recent years toward a very select market area, namely antiseptic products for use in cleaning and disinfection with a focus on food contact disinfection. However, H&S still offers and develops other product lines such as, Chloramine-T, Trichloromelamine, Hydriodic Acid, Methyl Fluoride, DDCP, HF-Pyridine, Optishield (specialty corrosion inhibitor) and Lampricide (pesticide for control of the Lamprey eel found in the Great Lakes), etc. By focusing on the disinfection and sanitization markets as well as other specialty products, H&S found it necessary to relocate the business from the Cincinnati facility to new facilities located in the Enterprise Zone of Covington, Kentucky. This location is about 10 miles south of downtown Cincinnati and 7 miles from the International Airport. These new facilities consist of two 1997 constructed buildings on 5.6 acres with an expanded R&D lab, quality control and analytical labs, offices and manufacturing.
