Harmaline is a fluorescent psychoactive indole alkaloid from the group of harmala alkaloids and beta-carbolines. It is a partially hydrogenated form of harmine. Harmaline is produced by various plants including Peganum harmala aswell as Banisteriopsis caapi. Harmaline has been investigated as an anti-cancer agent and for the treatment of dementia in rats. However, Harmaline is known to induce tremors in rats.

Zinc dibutyldithiocarbamate (Zn DBDTC) is a vulcanization accelerator for natural rubber and latex and a stabilizer for rubber-based adhesive systems, isobutylene-isoprene copolymers and polypropylene. It is used in a number of rubber and rubber-based materials for food packaging and food handling, e.g. conveyor belts. Zinc dibutyldithiocarbamate (Zn DBDTC) is contact allergens that cross-react in some individuals. Zinc dibutyldithiocarbamate, like many low-molecular-weight contact allergens, can only trigger an immune response when bound to a protein in the form of an immunogenic protein–hapten complex. Haptenation of epidermally relevant skin proteins by Zinc dibutyldithiocarbamate has not been reported despite the numerous studies on the disposition and systemic toxicity of Zinc dibutyldithiocarbamate. The chelating properties of the dithiocarbamate ligand have been proposed to be responsible for the modification of some metalloproteins and metalloenzymes

Bisphenol A diglycidyl ether (BADGE) is a ligand for peroxisome proliferator-activated receptor gamma (PPARgamma); in addition, this compound can antagonize the ability of agonist ligands such as rosiglitazone to activate the transcriptional and adipogenic action of this receptor. The elevation of BADGE concentration in epoxy resins-coated aluminium tubes poses a risk of developing contact dermatitis to patients sensitized to epoxy resins.

Dipentamethylenethiuram disulfide is an accelerator and vulcanizing agent used in the rubber industry. It can be found in latex gloves and other rubber products found in homes and offices. Dipentamethylenethiuram disulfide is a standardized chemical allergen. The physiologic effect of dipentamethylenethiuram disulfide is by means of increased histamine release, and cell-mediated Immunity. The chemical classification of dipentamethylenethiuram disulfide is allergens. It is used for diagnosis of contact allergy. It is a component of Thiuram Mix, used in the epicutaneous patch test, called T.R.U.E. TEST, approved by FDA in 1994. T.R.U.E. TEST is indicated for use as an aid in the diagnosis of allergic contact dermatitis in persons 18 years of age and older whose history suggests sensitivity to one or more of the 35 substances included on the T.R.U.E. TEST panels.

N-Cyclohexyl-N'-phenyl-1,4-phenylenediamine is a component of black rubber. It is also a dermatological sensitizer and allergen. N-Cyclohexyl-N'-phenyl-1,4-phenylenediamine is approved for use within allergenic epicutaneous patch tests which are indicated for use as an aid in the diagnosis of allergic contact dermatitis (ACD) in persons 6 years of age and older.
