|
Toxicity |
LD50 orally in Rabbit: 1700 mg/kg LD50 dermal Rabbit > 5000 mg/kg |
|
Chemical Properties |
Scaly or needle like crystals. With the smell of formaldehyde or benzene. Slightly soluble in water, soluble in ethanol, methanol, diethyl ether, chloroform, benzene, toluene, CS2, CCl4 and turpentine. |
|
Chemical Properties |
Benzoic acid occurs as feathery, light, white or colorless crystals or powder. It is essentially tasteless and odorless or with a slight characteristic odor suggestive of benzoin. |
|
Occurrence |
Reported found in fresh apple, apricot (Prunus armeniaca L.), strawberry fruit, cherry (Prunus cerasus L.), butter, boiled and cooked beef, pork fat, white wine, black tea, green tea, fresh plum, mushroom, Bourbon vanilla (Vanilla planifolia Andrews), and other natural sources. Reported as being a constituent of various oils, resins and flower absolutes; hyacinth, tuberose, neroli bigarade, Chinese cinnamon, cinnamon leaves, anise, vertiver, ylang-ylang, Tolu balsam and clove; it is contained in fairly sizable amounts in gum benzoin, from which benzoic acid is extracted by sublimation. |
|
Hazard |
Moderately toxic by ingestion. Use restricted to 0.1% in foods. |
|
Health Hazard |
Dust may be irritating to nose and eyes. At elevated temperatures, fumes may cause irritation of eyes, respiratory system, and skin. |
|
Fire Hazard |
Behavior in Fire: Vapor from molten Benzoic acid may form explosive mixture with air. Concentrated dust may form explosive mixture. |
|
Agricultural Uses |
Fungicide, Insecticide: Used in the manufacture of benzoates; plasticizers, benzoyl chloride, alkyd resins, in the manufacture of food preservatives, in use as a dye binder in calico printing; in curing of tobacco, flavors, perfumes, dentifrices, standard in analytical chemistry. Not currently registered for use in the U.S. Benzoic acid is currently used in about a dozen European countries. |
|
Pharmaceutical Applications |
Benzoic acid is
widely used in cosmetics, foods, and pharmaceuticals, as an antimicrobial
preservative. Greatest activity is seen at pH values between 2.5–4.5. |
