Citronellal is one of the main constituents of the essential oil from lemongrass (Cymbopogon). Citronellal is a major isolate from Cymbopogon plants, lemon-scented gum, and lemon-scented tea tree. Citronellal is a well-known plant-derived mosquito repellent. In addition, citronellal is very effective repellent against Sitophilus zeamais. Citronellal showed anticandidal activity against C. albicans and non-albicans species of Candida. Citronellal is effective as an analgesic compound in various rodent pain models, with its action probably mediated by the inhibition of peripheral mediators as well as central inhibitory mechanisms that could be related to its strong antioxidant effect observed in vitro.

Diethylamino hydroxybenzoyl hexyl benzoate (DHHB) is an organic UV filter with high absorption in the UV-A range that minimizes the overexposure of human skin to ultraviolet radiation that may lead to acute and chronic photodamage. In in vitro studies, DHHB was not shown to be mutagenic, clastogenic, or phototoxic. DHHB was approved in Europe in 2005, is also marketed in the U.S., South America, Mexico, Japan and Taiwan, and is used in concentrations up to 10% in sunscreen products, either alone or in combination with other UV absorbers. Only a minor amount of diethylamino hydroxybenzoyl hexyl benzoate will undergo percutaneous absorption and most will remain in the upper layers of the skin. Fluorescence spectroscopy showed that DHHB and avobenzone (another chemical sunscreen ingredient) interact by a static quenching mechanism and DHHB did not affect the avobenzone excited state lifetime.

Benzyl acetate is used as a fragrance ingredient and occurs in different plants and fruits, e.g., jasmine, apple, tea, plum, wine grape. It possesses a sweet and pleasant aroma, owing to which, it finds applications in personal hygiene and health care products.

Zingerone is one of the active phenolic components isolated from Zingiber officinale. Zingerone is primarily present in dry ginger, but cooking or drying also converts gingerol into zingerone by a retroaldol reaction. Chemically synthesized zingerone is vanillyl acetone, which is a member of the phenolic alkanone group, and its varied pharmacological properties include antioxidant, anti-inflammatory, and anticancer activities. Thus, zingeroneshowed strong anti-angiogenic activity via the inhibition of MMP-2 and MMP-9 during tumor progression. Zingerone was likely to be broad-spectrum anti-inflammatory agents in most organs that suppressed the activation of NF-κB, the production of IL-1β, and the infiltration of inflammatory cells in mice. Zingerone effectively inhibits 1,2-dimethylhydrazine-induced colon carcinogenesis in male Wistar rats. Zingerone possess radioprotective effects in laboratory animals and in cultured cells in vitro. Zingerone produced marked improvement in stress induced irritable bowel disorder, which could be attributed to the powerful antioxidant nature, direct effect on the intestinal smooth muscle and adaptogenic nature. Analysis of the qualities that constituted zingerone irritation found that the sensations produced are predominantly burning and warmth, making it qualitatively similar to capsaicin.
