LIMONENE, (±)- (Dipentene or Inactive limonene) is a colorless with a lemon-like odor terpene liquid. It is most commonly used as a solvent in a variety of products, like pesticides, paints, enamels, perfumes, hair color and others. Penetration of DL-limonene through the epidermis and dermis is very fast. Vere are some reports about contact dermatitis due to DL-limonene. Ingestion of dipentene can irritate the gastro-intestinal tract. DL-limonene may be recommended as a plant based antimicrobial as well as antioxidant food preservative for enhancement of shelf life of stored food commodities by checking their fungal growth, aflatoxin production and possessing antioxidant activity.

Alfadex also known as α-cyclodextrin, is used as an inactive ingredient in order to improve the water solubility of the different drugs, e.g. edex: is a sterile, pyrogen-free powder containing alprostadil in an alfadex inclusion complex. After intravenous infusion of radiolabeled α-cyclodextrin to healthy volunteers, the radiolabeled components were rapidly eliminated within 24-hours, urine accounting for 81-83% of radioactivity and feces for 0.1%. There was no evidence of significant accumulation of radiolabeled α-cyclodextrin in the body even after 7 days of repeated intravenous injection. After intracavernous administration in monkeys, radiolabeled α¬ cyclodextrin was rapidly distributed from the injection site with less than 0.1% of the dose remaining in the penis 1 hour after administration. There was no evidence of tissue retention of radiolabeled α-cyclodextrin in monkeys.

Norflurane (1,1,1,2-Tetrafluoroethane) is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. Other uses include plastic foam blowing, as a cleaning solvent, a propellant for the delivery of pharmaceuticals (e.g. bronchodilators), wine cork removers, gas dusters, and in air driers for removing the moisture from compressed air. Liquid Norflurane absorbs a high amount of thermal energy from the environment during its evaporation at atmospheric pressure. Norflurane is commercially available as a liquid in pressurized cylinders or cans. Norflurane is used as a propellant for some metered dose inhalers and as an inhalational anesthetic agent in animal studies.

OLEYL OLEATE is an inactive component of BUTRANS®, which is a partial opioid agonist indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Monoethanolamine is both a primary amine and a primary alcohol. It is an olamine derivative. Monoethanolamine occurs in every cell in the human body as the head group of Phosphatidylethanolamine. Monoethanolamine is a component of glycosylphosphatidylinositol-anchored proteins, which are essential for viability. Other sources of monoethanolamine or phosphoethanolamine in the human body are the degradation of sphingosine phosphate by sphingosine phosphate lyase and the degradation of the endocannabinoid anandamide by the fatty acid amine hydrolase. Monoethanolamine stimulates the rapid growth of mammalian cells in culture. Monoethanolamine has a cardioprotective role against ischemia/reperfusion injury via activation of the transcription factor STAT-3. Monoethanolamine is a chemical intermediate in the manufacture of cosmetics, surface-active agents, emulsifiers, pharmaceuticals, and plasticizing agents.

FD&C Yellow No. 5 (Tartrazine, Colour Index No. 19140) is a color additive permitted in the United States for coloring foods (including dietary supplements), ingested and externally applied drugs, and cosmetics. It is a nitrous derivative and is known to cause allergic reactions such as asthma and urticaria, as well as having been the focus of studies on mutagenesis and carcinogenesis due to its transformation into aromatic amine sulfanilic acid after being metabolized by the gastrointestinal microflora.

Sorbitan monostearate (Span 60) is a non-ionic surfactant with emulsifying, dispersing, and wetting properties used as a food additive, additive in mixtures for drug use and in skin care products. It is approved for use by FDA in quantities not exceeding the amount reasonably required to accomplish the intended effect. 0.5-5% of Liposorb® S (sorbitan monostearate) is used for oil-in-water emulsions in combination with a high hydrophilic-lipophilic balance emulsifier to produce smooth lotions and creams in skin and hair care, make-up bases, and mild cleaning products. Sorbitan monostearate based organogels and vesicles (niosomes) formulated to enhance the oral bioavailability were characterized for use as a drug delivery vehicle. In combination with other non-ionic surfactants sorbitan monostearate is patented for use in vaccine formulations as a saponin-containing adjuvant for oil-in-water injectable emulsions. It is fatty acid ester of sorbitan (a sorbitol derivative) and stearic acid sometimes called synthetic wax. Has low hydrophilic-lipophilic balance. Non-toxic.

Xylitol is a naturally occurring alcohol found in most plant material, including many fruits and vegetables. Xylitol is widely used as a sugar substitute and in "sugar-free" chewing gums, mints, and other candies. As a medicine, xylitol is used to prevent middle ear infections (otitis media) in young children, and as a sugar substitute for people with diabetes. Xylitol is added to some chewing gums and other oral care products to prevent tooth decay and dry mouth.

Rhodamine B is a fluorescent dye whose quantum yield is strongly dependent on temperature in the range of 0°C to 100°C, making it ideal for liquid based systems. It is a cell-permeant fluorogenic dye most often used as a conjugate to antibodies and proteins for fluorescence detection in microscopy. Rhodamine B is widely used in industrial purposes, such as printing and dyeing in textile, paper, paints, leathers etc. Rhodamine B was tested for use as a biomarker in oral rabies vaccines for raccoons, to identify animals that have eaten a vaccine bait. It has also been used as an anterograde and retrograde tracer in neurons and in nanoparticles to detect apoptosis.

Diethyl phthalate is a colourless liquid with a slight aromatic odour and low volatility. Diethyl phthalate is used as a plasticizer for cellulose ester plastic films and sheets (photographic, blister packaging, and tape applications) and moulded and extruded articles (consumer articles such as toothbrushes, automotive components, tool handles, and toys). Diethyl phthalate was reported as an ingredient in 67 cosmetic formulations. Diethyl phthalate is used as a component in insecticide sprays and mosquito repellents. Diethyl phthalate is likely to undergo biodegradation in the environment. General population exposure in the USA, as estimated from urinary concentrations of the monoester, was estimated to be 12 µg/kg body weight per day (median value). Dermally applied diethyl phthalate penetrates the skin and can be widely distributed in the body, but it does not accumulate in tissue. Diethyl phthalate has irritant effects on the eyes, skin, and mucous membranes and can lead to central nervous system (CNS) effects in exposed workers. The exposure to diethyl phthalates (DEP), a parent compound of the monoethyl phthalate (MEP) metabolite, may be associated with increased risk of BC (Odds Ratio of 2.20, p value for trend, p<0.003).
