Propyl benzoate, also known as benzoic acid propyl ester, is a naturally-occurring chemical compound found in clove stems and sweet cherries. This organic compound is used in a number of applications. It is characterized by a nutty odor and tastes like a sweet fruit, and hence used as a synthetic flavoring agent in foods. It also has antimicrobial properties and used as a preservative in the cosmetics industry. It is on FDA CFR - Code of Federal Regulations Title 21 list.

Sucrose octaacetate is an acetylated derivative of sucrose. It can be used as a bitter additive, a denaturant for alcohol, a soaker for paper, as well as an insecticide, plasticizer for cellulosic&synthetic resin. It also can be used as an additive for paint and children's toys, etc. It can prevent mice or children from biting or tasting the goods because of its extreme bitter taste. Sucrose octaacetate was determined by the EPA to be usable as an inert ingredient in pesticides due to its low toxicity

Denatonium, usually available as denatonium benzoate (trade names Bitrex) is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharide. Scientists at Macfarlan Smith, Ltd. of Edinburgh, Scotland discovered Bitrex during research on derivatives of the anesthetic lidocaine. The extremely bitter taste proved effective in reducing ingestion by humans and animals. Denatonium is commonly included in placebo medications used in clinical trials to match the bitter taste of certain medications. Denatonium activates bitter taste receptor, mainly, TAS2R4, TAS2R8, TAS2R10, TAS2R13 on many cell types and plays important roles in chemical release, ciliary beating and smooth muscle relaxation through intracellular Ca(2+)-dependent pathways.

Benzyl benzoate is an organic compound with the formula C6H5CH2O2CC6H5. It is the ester of benzyl alcohol and benzoic acid. It forms either a viscous liquid or solid flakes and has a weak, sweet-balsamic odor. It occurs in a number of blossoms (e. g. tuberose, hyacinth) and is a component of Balsam of Peru and Tolu balsam. It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system. Benzyl benzoate is one of the older preparations used to treat scabies. Scabies is a skin infection caused by the mite sarcoptes scabiei. It is characterised by severe itching (particularly at night), red spots, and may lead to a secondary infection. Benzyl benzoate is lethal to this mite and so is useful in the treatment of scabies. It is also used to treat lice infestation of the head and body. Benzyl benzoate is not the treatment of choice for scabies due to its irritant properties. Benzyl benzoate exerts toxic effects on the nervous system of the parasite, resulting in its death. It is also toxic to mite ova, though its exact mechanism of action is unknown. In vitro, benzyl benzoate has been found to kill the Sarcoptes mite within 5 minutes.
