Caprolactam (CED0005350)

Caprolactam belongs to the caprolactams, a subclass of lactams within the organic compounds. This organoheterocyclic compound has the chemical formula $\text{C}_6\text{H}_{11}\text{NO}$ and an average molecular weight of 113.16 g/mol. In industrial applications, it serves as a monomer, filler, flavouring and nutrient, and as a degradant or impurity. The compound is released from polyamide and is used in polypropylene, low-density polyethylene, and high-density polyethylene, though its presence in polyurethane, polyacrylonitrile, and polyethylene terephthalate remains inconclusive. Caprolactam is found in or released from 38 recorded sources. These include building and construction materials such as tents or canopies, ladders, stairs and ramps, and fencing. It is also associated with electrical and electronic equipment, including communication cables or conductors, coils, antennas, adjustable resistors, and auxiliary devices. Within household cleaning and consumer products, it is found in bleaching agents, ash trays, perfumes within detergents and soaps, cigar cigarettes, and non-electric simulated smoking devices. In the context of food, food processing, and cookware, it is linked to food preservation, processing meats, food contact materials, and fermentation processes for beer. Additionally, it is recorded in drinking water and indoor air. Human exposure to caprolactam occurs through touch, oral, and inhalation routes.
