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

Geraniol is a dietary monoterpene alcohol that is found in the essential oils of aromatic plants. To date, experimental evidence supports the therapeutic or preventive effects of geraniol on different types of cancer, such as breast, lung, colon, prostate, pancreatic, and hepatic cancer, and has revealed the mechanistic basis for its pharmacological actions. In addition, geraniol sensitizes tumor cells to commonly used chemotherapy agents. Geraniol controls a variety of signaling molecules and pathways that represent tumor hallmarks; these actions of geraniol constrain the ability of tumor cells to acquire adaptive resistance against anticancer drugs. It has been shown that geraniol inhibits HMG-CoA reductase in most types of tumor cells, which raises the possibility that the reduced prenylation of small G-proteins, such as Ras or RhoA, accounts for the antitumor effects of geraniol. In addition to its use in various commercial products, including cosmetics and fine fragrances, geraniol exerts a broad spectrum of pharmacological activities, such as anti-microbial, anti-inflammatory, anti-oxidant, anti-ulcer and neuroprotective activities. Geraniol is classified into the generally recognized-as-safe (GRAS) category by the Flavor and Extract Manufacturers Association (FEMA) and the Food and Drug Administration (FDA) of the United States.

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.

Cinnamyl alcohol (CAL, 3-phenyl-2-propen-1-ol) is found mostly in esterized form as a natural component in cinnamon oil obtained from the bark of the Cylonese cinnamon tree. Furthermore, (esterized) CAL is a component of the balsam of Peru from Myroxylon pereirae, of Styrax (balsam) from the wood of Liquidambar orientalis Miller or Liquidambar styraciflua L. and further plant extracts. The regulatory status of CAL includes approval (21 CFR 172.515) by the FDA and Generally Recognized as Safe (GRAS) as flavor ingredient [Number 2294] by the Flavor and Extract Manufacturers
Association. CAL included in the Council of Europe
s list of substances which may be used in foodstuffs. CAL have been reported as common component of food occurring mainly in a wide variety of fruits, vegetables, and spices in varying concentrations. The plant phenolic CAL is used as a fragrance ingredient and has antipyretic and antiproliferative effects. A recent report also demonstrated its vasodilatory activity.

Nickel (II) oxide is an olive gray powder, insoluble in water and soluble in acids. It is produced industrially and used mainly as an intermediate in the production of nickel alloys and as a hydrogenation catalyst. Long-term inhalation of NiO is damaging to the lungs, causing lesions and in some cases cancer.

Gold monoiodide (AuI; Aurum iodatum) is a chemical compound of gold and iodine. This compound can be synthesized by heating gold and iodine in a sealed tube at 120°C for about four months. It decomposes when treated with hot water, but its related complexes are much more stable. It’s used like unapproved homeopathic product for treatment of Senile Paresis. This product is to be used for self-limiting conditions. If symptoms do not improve in 4 days, or worsen, discontinue use and seek assistance of health professional

N-isopropyl-N'-phenylparaphenylenediamine (IPPD), an amine antiozonant, is used in rubber manufacture and is a human allergen.

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.

Sodium dichromate is an inorganic compound, containing hexavalent chromium. It is highly corrosive and is a strong oxidizing agent. Sodium dichromate is mainly used to produce other chromium compounds but is also used in drilling muds, in metal treatments, in wood preservatives, in the production of dyes and organic chemicals and as a corrosion inhibitor. Sodium dichromate primarily affects the respiratory system causing ulcerations, shortness of breath, bronchitis, pneumonia, and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. This substance is a known human carcinogen and is associated with an increased risk of developing lung cancer and cancer of the sinonasal cavity.

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.
