Could nitrile gloves cause allergies?

Nitrile gloves may cause, in rare cases, delayed allergies also known as IV Type Hypersensitivity Reactions or Contact Allergies due to chemical residues in the production process. In recent years, new gloves manufacturing techniques and prolonged washing treatments at the end of the production process have greatly reduced the amount of chemical additives present on the gloves and, for this reason, reactions to nitrile gloves are very rare.
