p-Menthane-3,8-diol is a biochemical pesticide derived from eucalyptus plants. This active ingredient is used to make products that are applied to human skin and clothing for the purpose of repelling insects, such as mosquitoes. It can be used in two types of consumer pesticide products: a spray and a lotion. When used according to the label, p-Menthane-3,8-diol products are not expected to cause harm to humans or the environment. p-Menthane-3,8-diol is used on humans and their clothing to repel insects. Studies have shown that p-Menthane-3,8-diol gives protection against the biting midge, Culicoides variipennis Coquillett, the deer tick, Ixodes ricinis L., and the stable fly, Stomoxys calcitrans L. P-menthane-3,8-diol (PMD) has being studied as an antiviral agent.

Betulin is an extract from bark of the white birch tree, which has been known since the 18th century and is chemically defined. Betulin was discovered by German-Russian chemist Johann Tobias Lowitz. He was the first scientist to study and characterise betulin, and in doing was one of the first to isolate an active plant ingredient. In numerous scientific studies, the natural active ingredient betulin has been found to have anti-inflammatory, anti-bacterial and regenerating properties. Birken AG creates a patented process for extracting high-quality betulin from birch bark. Betulin works as keratinocyte modulator and transient receptor potential channel stimulant. An extensive study program including three clinical phase III trials was initiated to develop the drug candidate Oleogel-S10, Betulin-based oleogel, as the lead indication for accelerated wound healing of partial thickness wounds. In addition, Oleogel-S10 obtained the Orphan Drug Designation for the treatment of hereditary skin disorder Epidermolysis bullosa (EB) from the European Commission. Betulin can be easily converted to betulinic acid, which possesses a wide spectrum of biological and pharmacological activities. Betulinic acid has antimalarial and anti-inflammatory activities. Betulinic acid and its derivatives have especially shown anti-HIV activity and cytotoxicity against a variety of tumor cell lines comparable to some clinically used drugs.

Imidazole is a planer five-member heterocyclic ring with 3C and 2N atom and in ring N is present in 1st and 3rd positions. The imidazole ring is a constituent of several important natural products, including purine, histamine, histidine and nucleic acid. Being a polar and ionisable aromatic compound, it improves pharmacokinetic characteristics of lead molecules and thus used as a remedy to optimize solubility and bioavailability parameters of proposed poorly soluble lead molecules. The imidazole derivatives possess extensive spectrum of biological activities such as antibacterial, anticancer, antitubercular, antifungal, analgesic, and anti-HIV activities. The organic compound is used in the chemical industry as an intermediate in the production of pharmaceuticals, pesticides, dye intermediates, auxiliaries for textile dyeing and finishing, photographic chemicals and corrosion inhibitors. The chemical possesses properties (corrosivity to skin, irreversible damage to eyes, teratogenic effects) indicating a hazard for human health. Humans are exposed by consumer products (chemical concentrations up to 10%) and at the workplace. Therefore, the chemical is a candidate for further work. An exposure assessment and if indicated a risk assessment is recommended.
