2,2'-dithiobisbenzothiazole is a Standardized Chemical Allergen as labeled by US Food and Drug Administration. and can cause an allergic contact dermatitis.Its physiologic effect is by means of increased histamine release, and cell-mediated immunity. 2,2'-dithiobis(benzothiazole) is a useful compound in the rubber industry as a vulcanization accelerator. 2,2'-dithiobis(benzothiazole) was marketed to the rubber industry under the tradename Altax(TM) by the R. T. Vanderbilt Company, Inc. and was originally developed for safe processing of rubber compounds cured at above 142° C. 2,2'-dithiobis(benzothiazole) is widely used in compounds of all types for many major commercial applications. It may be carcinogenic for human. The mortality (1955-2005) and cancer morbidity experience (1971-2005) of a cohort of 363 male production workers exposed to MBT while employed at a chemical factory in north Wales showed a significant excess mortality for cancers of the large intestine.

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.
Imidurea (Imidazolidinyl urea) is used as an antimicrobial agent and preservative in cosmetics and toiletries. It is very active against gram and gram- bacteria as a synergist in combination with parabens. Imidazolidinyl urea is more active against bacteria than fungi and is often combined with parabens to provide a broad spectrum preservative system. This preservative is one of the most widely used preservative systems in the world. The Food and Drug Administration (FDA) considers imidazolidinyl urea as one of the most common antimicrobial agents used in cosmetics. Due to its high water solubility, imidazolidinyl urea can be incorporated into almost all water-based cosmetics, toiletries, and cold mix formulations. It is present in a wide range of liquid and powder products such as baby lotion, skin cream, sunscreens, shampoos, eyeliners, blush, perfumes, deodorants, hair dyes, shaving cream, and face masks. Imidazolidinyl urea is permitted for use in personal care products in the European Union at a maximum concentration of 0.6%. In Japan, imidazolidinyl urea is allowed in rinse-off cosmetics such as shampoo, body wash, and facial cleanser at a maximum concentration of 0.3%. Imidurea is an ingredient of FDA-approved NIZORAL® (ketoconazole) 2% Shampoo, indicated for the treatment of tinea (pityriasis) versicolor caused by or presumed to be caused by Pityrosporum orbiculare (also known as Malassezia furfur or M. orbiculare).
Cinnamaldehyde is one of the active compounds found in cinnamon. It was reported that cinnamaldehyde has anti-diabetic, anti-cancer, antimicrobial and anti-inflammatiry activity. Cinnamon is a common prescription compound in traditional Chinese medicine and it is used as a dietary supplement all over the world. Cinnamon dietary supplement Cinnamonforce (min. 35% cinnamaldehyde) was tested in phase II clinical trials and demonstrated therapeutic activity in patients with type 2 diabetes. The mechanism of cinnamaldehyde possibly involves the activation of PPAR gamma/delta receptors. Cinnamaldehyde is partially metabolized into cinnamic acid in the stomach and small intestine, and is almost completely metabolized into cinnamic acid in the liver. Cinnamic acid is believed to be the active metabolite, which is responsible for anti-diabetic properties of cinnamaldehyde.

Ethylenediamine is a strongly basic amine useful as a building block in chemical synthesis. It is used as a solvent to dissolve proteins such as albumins, casein and in medicine to stabilize aminophylline when used in injections. Ethylenediamine is used in manufacture of chelating agents (EDTA), epoxy curing agents, dimethylolethylene-urea resins, emulsifying agents, textile lubricants, antifreeze inhibitor. It is also involved in the manufacture of many industrial chemicals and forms derivatives with carboxylic acids, nitriles, alcohols, alkylating agents, carbon disulfide, aldehydes and ketones. It is a basic building block to prepare heterocyclic compound such as imidazolidines.
Propylparaben is a bacteriostatic and fungistatic agent used as a preservative in cosmetic products, food and drugs. As a food additive, it has the E number E216. To increase the activity and reduce its dose propylparaben is used in a mixture with other parabens and in combination with other types of preservatives. Propylparaben is a chemical allergen capable of producing immunologically mediated hypersensitivity reactions. Chemically it is an ester of p-hydroxybenzoic acid.

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.

Chlorquinaldol is a halogenated hydroxyquinoline with properties similar to those of clioquinol. It is mainly applied topically in infected skin conditions and in vaginal infections. The product is applied for local treatment of cortico-sensitive dermatosis with moderately manifested superinfection, acute and subacute eczema, dermatitis, pyodermia, intertrigo, infected wounds, dermatomycosis, pemphigus in newborn. Chlorquinaldol is also used as antiseptic, fungistat, or deodorant. Chlorquinaldol is not commercially available in the U.S. but is used in other countries principally as an amebicide for nonspecific diarrheas and gynecologic infections. It is known most commonly under the proprietary name of Sterosan. Other trade names include Cynotherax, Gyno-Sterosan, Saprosan, Siogeno, Siosteran, Slosteran and Steroxin.

Eugenol is sometimes called clove oil because it is the active element in cloves. It causes the aromatic smell typical of cloves and because of this property is often found in perfumes. Eugenol’s properties make it a good local antiseptic and analgesic. It is used in dentist offices to make zinc-oxide eugenol paste for temporary fillings. Eugenol also demonstrates antifungal and antimicrobial activity, showing efficacy against Candida albicans biofilms, Listeria monocytogenes and Escherichia coli. Eugenol is further described to induce reactive oxygen species (ROS) production and to scavenge ROS, thus demonstrating prooxidant and antioxidant effects. Also, Eugenol is used as a pesticide.
