Tixocortol is a synthetic steroid with topical anti-inflammatory properties. In form of Tixocortol pivalate, also known as Pivalone, it is used to treat the inflammatory and allergic manifestations of the rhino-pharynx: allergic rhinitis, acute and chronic congestive rhinitis, vasomotor rhinitis. In addition, it has been shown to be a useful agent for assessing corticosteroid contact dermatitis, particularly for hydrocortisone-type derivatives. Labeled adverse effects are: itchy nose, dryness of the nasal mucosa, edema of the face mucosa, cataract, glaucoma, Cushing syndrome, skin thinning.

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.
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.
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.

2-Mercaptobenzothiazole (MBT) can be a human carcinogen. It causes allergic contact dermatitis. For external animal use only: for Dogs, Cats and Horses it’s used to afford relief to certain common skin problems sometimes referred to as summer eczema, kennel itch, or hot spots (moist dermatitis). These conditions are characterized by intense itching and scratching, followed by rough scaly skin, and hair loss. Skin Balm relieves itching, softens the skin and helps return your animals' coat and skin to a healthy state.

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.

Methylparaben (E number E218) is preservative in the food, cosmetic, and pharmaceutical industries. It is completely absorbed through the skin or after ingestion and and it is hydrolyzed to para-hydroxybenzoic acid, and metabolites are rapidly excreted in the urine. Methylparaben is on the FDA generally regarded as safe list.
