Panthenyl ethyl ether is used in cosmetic as an antistatic and hair conditioning. However, it was found that in patients with psoriasis panthenyl ethyl ether could cause allergic contact dermatitis.

Bisoctrizole (Tinosorb M) is a hybrid type sun blocking agent acting as both chemical and physical sunscreen. Bisoctrizole is a hybrid UV absorber, the only organic UV filter produced and microfine organic particles (< 200 nm), like microfine zinc oxide and titanium dioxide. Where other organic UV absorbers need to be dissolved in either the oil or water phase, bisoctrizole dissolves poorly in both. It covers both UVA and UVB range. Furthermore, it does not degrade under sunlight and is not significantly absorbed into the skin. It appear highly compatible with many other common sun blocking agents. Overall, it appears to have a good safety profile, even though current safety data are insufficient and long-term human safety studies are lacking. Unlike some other organic sunscreen actives, it shows no estrogenic effects in vitro. Bisoctrizole is not approved by the U.S. Food and Drug Administration (FDA), but is approved in the EU and other parts of the world. Bisoctrizole is highly stable and also has a stabilizing effect on other UV absorbers, particularly the UVB blocker octyl methoxycinnamate (octinoxate). Bisoctrizole appears to be relatively non-toxic and rarely causes skin irritation. As with many synthetic chemicals, it is unclear whether bisoctrizole may produce low-level skin damage or systemic effects with long-term use. Considering that bisoctrizole is stable, poorly soluble and minimally absorbed by the skin, the risks appear to be low. Still, more research is on bisoctrizole safety is needed.

Doconexent (Docosahexaenoic acid, DHA) is an omega-3 fatty acid that is a primary structural component of the human brain, cerebral cortex, skin, and retina. DHA is widely used as a food supplement, and is beleived to support healthy brain development in young childred, prevent cardiovascular disease and cognitive decline during Alzheimer's disease. Most of these claims, however, were not supported by clinical trials. DHA spray is used as a tanner.

Erythorbic acid, an epimer of L-ascorbic acid, is used in the United States as a food additive. It was studied, that erythorbic acid enhanced of iron absorption and could play a major role in enhancing iron bioavailability from mixed diets that include foods preserved with erythorbic acid. In addition, was investigated if the erythorbic acid could influence on the metabolism of vitamin C in young women, and obtained results showed, that prolonged ingestion of erythorbic acid had no effect on vitamin C uptake or clearance from the body.

Gentisic acid is an active metabolite of salicylic acid degradation, which possesses a broad spectrum of biological activity, such as anti-inflammatory, antirheumatic and antioxidant properties. The antioxidant activity and radioprotective properties of gentisic acid are exerted by its phenoxyl group. It is also used in cosmetics as a skin-whitening agent for the treatment of skin pigmentary disorders by influencing the synthesis of melanin through inhibition of melanosomal tyrosinase activity Gentisic acid is also a biomarker of Renal Cell Carcinoma.

Vitamin E quinone Alpha-tocopherylquinone is formed during free radical attack on vitamin E and has been shown to undergo reduction by NQO1 (NAD(P)H dehydrogenase [quinone] 1) to generate vitamin E hydroquinone. Since it has been recognized that alpha-tocopherylquinone in living tissue for global assessment of antioxidative defense system. The ratio of alpha-tocopherol alpha-tocopherylquinone concentrations were increased under oxidative stress with the exception of plasma. Alpha-tocopherylquinone and a low fat diet have positive effect on a patient with chronic continuous ulcerative colitis. The patient's condition improved dramatically with both colonic and extraintestinal manifestations of the disease. Withdrawal of alpha-tocopherylquinone for periods of one to two days produced recurrence of inflammation, which was again reduced upon re-introduction of alpha-tocopherylquinone.

Pimobendan (INN, or pimobendane; tradenames Vetmedin, Acardi, and Heartmedin) is a veterinary medication. Under the trade name Acardi, it is available for human use in Japan. Usually, this medicine is used to treat acute heart failure and chronic heart failure (mild to moderate in severity). By increasing the calcium ion sensitivity to protein regulating myocardial contraction and also by inhibiting phosphodiesterase (PDE-III) activity, this medicine dilates the blood vessels and improves the symptoms of heart failure such as shortness of breath and difficulty in breathing. Pimobendan is metabolized into an active metabolite (desmethylpimobendan) by the liver. The parent compound, pimobendan, is a potent calcium sensitizer while desmethylpimobendan is a more potent phosphodiesterase III inhibitor. Pimobendan is 90–95% bound to plasma proteins in circulation. This may have implications in patients suffering from low blood protein levels (hypoproteinemia/hypoalbuminemia) and in patients that are on concurrent therapies that are also highly protein bound.
