Parabens are widely used preservatives in basic necessities such as cosmetic and pharmaceutical products. It was found, that butylparaben has estrogenic and antiandrogenic properties and is known to reduce sperm counts in rats following perinatal exposure. In addition was observed, that butylparaben exerted endocrine disrupting effects on both male and female offspring. In 2009-2010, 80 pregnant women from Ottawa Canada participated in the Plastics and Personal-Care Product Use in Pregnancy (P4) Study. Women kept a diary of products that they used 24 h prior to and during the collection. All parabens measured in maternal urine had moderate to high reproducibility. Women who used lotions in the past 24 h had significantly higher geometric mean paraben concentrations (80-110%) in their urine than women who reported no use in the past 24 h. Women who used shampoo, conditioner, and cosmetics also showed 70-80% higher butylparaben concentrations in their urine.

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.

Silver benzoate is a water soluble crystalline salt composed of silver and benzoic acid with the formula C7H5AgO2 with marked antimicrobial activity. Silver benzoate can be used in synthesis of silver nanoparticle, and in the synthesis of triphenyltinbenzoate. Silver benzoate along with 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTBD) is an efficient catalytic system for the reaction of carbon dioxide with various ketones.

Benzyl mandelate is of comparatively low toxicity on the one hand and is pharmacologically effective on the other hand. The most important pharmacological action of the drug is on smooth muscle. Benzyl mandelate has been used for its antispasmodic actions. It has also been included in preparations with analgesics in an attempt to increase the analgesic effect. Drugs with benzyl maleate were indicated for the angina prevention and for pain condition treatment.
