Tolnaftate is a thiocarbamate derivative used as an over-the-counter anti-fungal agent for treatment of athlete's foot and ringworm. Tolnaftate acts by inhibition of ergosterol biosynthesis pathway in fungal cells.

Selenium sulfide, an anti-infective agent, relieves itching and flaking of the scalp and removes the dry, scaly particles that are commonly referred to as dandruff or seborrhea. It is also used to treat tinea versicolor, a fungal infection of the skin. Topical selenium sulfide can be added to the therapeutic armamentarium for congenital or acquired hyperkeratosis.

Undecylenic acid is unsaturated fatty acid, which naturally occurs in sweat, and is commercially produced by the vacuum distillation of castor bean oil. It is recognized as GRASE by FDA, and is marketed over the counter to treat skin infections and to relieve itching. Undecylenic acid acts by inhibition of morphogenesis from yeast to hyphae forms.

Methyl salicylate (or methyl 2-hydroxybenzoate), also known as wintergreen oil, is a natural product and is present in white wine, tea, porcini mushroom Boletus edulis, Bourbon vanilla, clary sage, red sage and fruits including cherry, apple, raspberry, papaya and plum. Methyl salicylate is topically used in combination with methanol and under brand name SALONPAS to temporarily relieves mild to moderate aches and pains of muscles and joints associated with: strains, sprains, simple backache, arthritis, bruises. The precise mechanism of action of methyl salicylate is not known, but there is suggested, that it cause dilation of the capillaries thereby increasing blood flow to the area.

Thiabendazole (TBZ, trade names Mintezol, Tresaderm, and Arbotect) was first introduced in 1962. This drug is a fungicide and parasiticide and is indicated for the treatment of: strongyloidiasis (threadworm), cutaneous larva migrans (creeping eruption), visceral larva migrans, trichinosis: relief of symptoms and fever and a reduction of eosinophilia have followed the use of this drug during the invasion stage of the disease. But usage of this drug was discontinued. The precise mode of action of thiabendazole on the parasite is unknown, but it may inhibit the helminthspecific enzyme fumarate reductase. It was shown, also that thiabendazole reversibly disassembles newly established blood vessels, marking it as vascular disrupting agent (VDA) and thus as a potential complementary therapeutic for use in combination with current anti-angiogenic therapies. Was shown, that vascular disruption by TBZ results from reduced tubulin levels and hyper-active Rho signaling. In addition, was confirmed, that thiabendazole slowed tumor growth and decreased vascular density in preclinical fibrosarcoma xenografts and thus, it could lead directly to the identification of a potential new therapeutic application for an inexpensive drug that is already approved for clinical use in humans.

Gentian violet ((GV) hexamethyl pararosaniline, also known as crystal violet, methyl violet) is a triphenylmethane dye with anti-bacterial, anti-fungal, anti-helminithic, anti-trypanosomal, anti-angiogenic and anti-tumor properties. GV has a lengthy history and has been used successfully as monotherapy and an adjunct to treatment in a variety of diseases. Gentian violet interacts with negatively charged components of bacterial cells including the lipopolysaccharide (on the cell wall), the peptidoglycan and DNA. A similar cell penetration and DNA binding process is thought to take place for fungal cells as well. Because Gentian violet is a mutagen and mitotic poison, cell growth is consequently inhibited. A photodynamic action of gentian violet, apparently mediated by a free-radical mechanism, has recently been described in bacteria and in the protozoan T. cruzi. Evidence also suggests that gentian violet dissipates the bacterial (and mitochondrial) membrane potential by inducing permeability. This is followed by respiratory inhibition. This anti-mitochondrial activity might explain gentian violet's efficacy towards both bacteria and yeast with relatively mild effects on mammalian cells.

Amorolfine (or amorolfin), is a morpholine antifungal drug with broad spectrum of activity. Its fungicidal action is based on an alteration of the fungal cell membrane targeted primarily on sterol biosynthesis. Amorolfine is administered as a nail lacquer in patients suffering from onychomycosis, as a cream in patients suffering from dermatomycosis. Amorolfine is well tolerated. The local adverse effects observed were mainly burning and itching.

Chlorphenesin is a preservative and cosmetic biocide that helps prevent the growth of microorganisms. In cosmetics and personal care products, Chlorphenesin is used in the formulation of aftershave lotions, bath products, cleansing products, deodorants, hair conditioners, makeup, skin care products, personal cleanliness products, and shampoos. Chlorphenesin has been reported to cause irritation and contact dermatitis in some people, particularly those with sensitive and dry skin. The Cosmetic Ingredient Review (CIR) expert panel released a safety assessment in October 2012, however, that stated chlorphenesin at 0.3 percent (as it exists in personal care products) was classified as having “negligible dermal irritation potential.”

Ethylparaben is produced naturally and found in several fruits and insects, where it acts as an antimicrobial agent. Ethylparaben is mainly used as antiseptics in cosmetics, food and medicine (E number E214). It is also can be used as feed preservatives and antiseptic for bacteria. Ethylparaben is readily absorbed from the gastrointestinal tract or through the skin. It is hydrolyzed to p-hydroxybenzoic acid and rapidly excreted in urine without accumulating in the body. Under the Federal Food, Drug, and Cosmetic Act (FD&C Act), cosmetic products and ingredients, other than color additives, do not need FDA approval before they go on the market. Broad concentration ranges reported in each product category in 1981 were < 0.1% and > 0.1% to 1%. Studies show the in vivo estrogenicity of MP and EP at human exposure levels, and indicate that populations exposed to large amounts of MP and EP may have a high burden of estrogenicity-related diseases.

Chlormidazole was the first azole introduced the treatment of topical mycosis. It demonstrated inhibitory activity against many fungi and some gram-positive cocci. It is used for the treatment of fungal and bacterial infections of nails and skin, including interdigital and periungual mycoses. Possible side effects are: local skin irritation, burning, itching.
