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.

Benzyl cinnamate (also known as Jacobson's solution) was used to treat chronic salpingitis, and in combination with vitamin A to treat cerebrovascular lesions. In addition, it is used in heavy oriental perfumes and as a fixative and as a flavoring agent.

Benzyl chloride, or α-chlorotoluene, is a reactive organochlorine compound that is a widely used chemical building block. Industrially, benzyl chloride is the precursor to benzyl esters which are used as plasticizers, flavorants, and perfumes. Phenylacetic acid, a precursor to pharmaceuticals, is produced from benzyl cyanide, which is generated by treatment of benzyl chloride with sodium cyanide. Quaternary ammonium salts, used as surfactants, are readily formed by alkylation of tertiary amines with benzyl chloride. Benzyl chloride is an alkylating agent with very irritating properties to the skin. Indicative of its high reactivity (relative to alkyl chlorides), benzyl chloride reacts with water in a hydrolysis reaction to form benzyl alcohol and hydrochloric acid. In contact with mucous membranes, hydrolysis produces hydrochloric acid. Thus, benzyl chloride is a lachrymator and has been used in chemical warfare.

Estriol acetate benzoate is a semisynthetic, steroidal estrogen. Estriol benzoate diacetate is reported as an ingredient of Holin in Japan. It is an estrogen receptor agonist.

Betamethasone and its derivatives, betamethasone sodium phosphate and betamethasone acetate, are synthetic glucocorticoids. Used for its antiinflammatory or immunosuppressive properties, betamethasone is combined with a mineralocorticoid to manage adrenal insufficiency and is used in the form of betamethasone benzoate, betamethasone dipropionate, or betamethasone valerate for the treatment of inflammation due to corticosteroid-responsive dermatoses. Betamethasone and clotrimazole are used together to treat cutaneous tinea infections. Betamethasone is a glucocorticoid receptor agonist. This leads to changes in genetic expression once this complex binds to the GRE. The antiinflammatory actions of corticosteroids are thought to involve lipocortins, phospholipase A2 inhibitory proteins which, through inhibition arachidonic acid, control the biosynthesis of prostaglandins and leukotrienes. The immune system is suppressed by corticosteroids due to a decrease in the function of the lymphatic system, a reduction in immunoglobulin and complement concentrations, the precipitation of lymphocytopenia, and interference with antigen-antibody binding. Betamethasone binds to plasma transcortin, and it becomes active when it is not bound to transcortin.Betamethasone is used for: treating certain conditions associated with decreased adrenal gland function. It is used to treat severe inflammation caused by certain conditions, including severe asthma, severe allergies, rheumatoid arthritis, ulcerative colitis, certain blood disorders, lupus, multiple sclerosis, and certain eye and skin conditions.

Estradiol benzoate is the synthetic benzoate ester of estradiol, a steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. This agent exhibits mild anabolic and metabolic properties, and increases blood coagulability. Although estradiol benzoate is not approved by the FDA for use in humans in the United States, it is approved for veterinary use as a subdermal implant both alone (CELERIN®) and in combination with the anabolic steroid trenbolone acetate (SYNOVEX® Plus).
