Nicotinamide hydrochloride, also known as nicotine, is a derivative of nicotine and is commonly used as a flavor additive and preservative in food products. It is also used in pharmaceuticals and cosmetics, as an insect repellent, and as a corrosion inhibitor.
Rubber materials can be adversely affected when exposed to nicotine. The material may become brittle, discolored, swell, or display signs of cracking or crazing. The rubber may also experience an increase in permeability, leading to a decrease in the effectiveness of the seal. Additionally, the rubber may become soft and gummy, causing an increase in deformation.
