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

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.

Thiram is a pesticide, It is used as a fungicide, ectoparasiticide to prevent fungal diseases in seed and crops. It is also used as an animal repellent to protect fruit trees and ornamentals from damage by rabbits, rodents and deer. Thiram belongs to the ethylene bisdithiocarbamate (EBDC) chemical class. It is available as dust, flowable, wettable powder, water dispersible granules, and water suspension formulations and in mixtures with other fungicides. Thiram has been used in the treatment of human scabies, as a sun screen and as a bactericide applied directly to the skin or incorporated into soap. Thiram is a skin sensitizer. It is moderately toxic by ingestion, but it is highly toxic if inhaled. Acute exposure in humans may cause headaches, dizziness, fatigue, nausea, diarrhea and other gastrointestinal complaints. In rats and mice, large doses of thiram produced muscle incoordination, hyperactivity followed by inactivity, loss of muscular tone, labored breathing, convulsions and death.

p-Phenylenediamine is one of the simplest aromatic diamine primarily used as a component of engineering polymers, composites, dye intermediate and as a hair dye. p-Phenylenediamine is easily oxidized, and for this reason derivatives of p-Phenylenediamine are used as antiozonants in the production of rubber products. The substituents, naphthyl, isopropyl etc. affect the effectiveness of their antioxidant roles as well as their properties as skin irritants. Acute (short-term) exposure to high levels of p-phenylenediamine may cause severe dermatitis, eye irritation and asthma, gastritis, renal failure, vertigo, tremors, convulsions, and coma in humans. Eczematoid contact dermatitis may result from chronic (long-term) exposure in humans. In rats and mice chronically exposed to p-phenylenediamine in their diet, depressed body weights, but no other clinical signs of toxicity were observed in several studies. No information is available on the reproductive, developmental, or carcinogenic effects of p-phenylenediamine in humans. EPA has not classified p-phenylenediamine with respect to carcinogenicity.

Benzylparaben (BzP), a type of parabens being used as a preservative agent in cosmetics, food, and pharmaceutical products. It is an allergic compound, which was shown to fit well into the agonist pocket of human estrogen receptor α (hERα).

Tetramethylthiuram monosulfide (TMTM) is used as a secondary accelerator and activator in the processing of natural and butyl rubbers. It is used as a fungicide, and insecticide.

Bronopol is used as a preservative in various cosmetic, pharmaceutical, toiletry and household preparations at concentrations of up to 0.1% (wt/vol) particularly because of its high activity against Gram-negative bacteria, especially Pseudomonas aeruginosa and other pseudomonad. Bronopol hydrolyzes within 3 h at 60 °C and pH 8, producing formaldehyde, nitrosamines, and other molecules. Although the parent compound (bronopol) is rather short-lived in the environment, its degradation products are toxic and more persistent. The protection against the bactericidal activity of bronopol afforded by catalase or superoxide dismutase suggests that the activity stems from the aerobic interaction and the generation of active oxygen species from oxygen diffusing into the suspensions during bronopol treatment. The acute oral LD50 was 307 mg/kg for rat males and 342 mg/kg for females. Bronopol is moderately toxic by the oral route. Results from an acute dermal toxicity study while inadequate, suggest bronopol is highly toxic by the dermal route.

Quaternium-15, a preservative, is one of the most used substances and is added to several cosmetics and other industrial products. Quaternium-15 is a mixture of isomers, where the cis-form is the dominant form and where the trans-form is the minor component present as an impurity. Quaternium-15 can be found under a variety of names, most commonly those of the Dow Chemical Company: Dowicil 200 (cis isomer only), Dowicil 75 and Dowicil 100 (both a mix of cis and trans isomers). The isolated cis-compound is used primarily in cosmetic applications, with a maximum permitted concentration in the EU of 0.2%. DOWICIL 200 preservative (cis form) is used primarily as a preservative in a wide variety of personal-care and cosmetic products. It is designed to provide highly effective broad-spectrum antimicrobial activity, especially in water-based formulations. It is used in both leave-on and rinse-off application such as baby-care products, hair-care products, lotions, powders, and creams. The mixed product (cis- and trans-) is used in a wider range of formulations such as: emulsifiable metal-cutting fluids; latex and emulsion paints; liquid floor polishes and floor waxes; glues and adhesives. Recently, the cis-form has been classified as a CMR substance with the classification toxic to reproduction, category 3. This classification only concerns the cis-isomer:

Sodium 2-Mercaptobenzothiazole (sodium MBT) is utilized as a corrosion inhibitor and fungicide. By analogy to MBT, sodium MBT is identified as a skin sensitizer. Sodium 2-Mercaptobenzothiazole is also used to make rubber accelerators, as a preservative for latex paint and wood, a metal chelator, and a thermal stabilizer (methyl methacrylate copolymers, acrylonitrile polymers, polyester fibers, anion exchange resins, polyoxyphenylene, and silicon fluids), also used in electroplating (silver, nickel, and cobalt), to separate sulfide ore from copper ore, for dyeing textiles, in transmission fluids, and to prevent discoloration of freeze dried bananas; uses of 50% aqueous solution include as a corrosion inhibitor for nonferrous metals in antifreeze and coolants and in paper mill systems; used as a biocide in metalworking fluids and paper manufacturing.

There is not much information about ammonium phenolate. It is known, that this a salt of phenol and it is toxic if swallowed and is toxic in contact with skin.
