A Redetermination of the Salicylic Acid Yield in the Aqueous Calcium Benzoate Dosimeter:
G(salicylic acid) or G(Sal) has been determined for 10-3M and 1-4 M aqueous calcium benzoate solutions irradiated with Co60 - rays, 250-Kvcp x rays, 100-Kvcp x rays, and 50-Kvcp x rays. 
The G(Sal) values for Co60 rays of 0.655 (10-3 M) and 0.595 (10-4 M) are about 6% lower than previously determined values. 
Possible sources of error in the measurements have been examined and discussed. 
For the measurement of low doses (16 rads), the use of chromic acid for cleaning irradiation vessels has been shown to yield irreproducible results.

What is calcium bezoate?
Calcium benzoate is commonly used as a food preservative. 
Calcium benzoate is effective against yeasts, moulds, and certain types of bacteria. 
Calcium benzoate is currently approved for use in the EU, Austalia, and New Zealand.

Description
In its raw form, calcium benzoate appears as a white crystalline powder. 
Calcium benzoate is a calcium salt of benzoic acid. In chemistry, the term salt refers to a particular set of compounds (ionic compounds) that result when an acid is neutralized by a base. 
In this case, benzoic acid, C6H5COOH, reacts with calcium hydroxide, Ca(OH)2, to form the salt calcium benzoate, Ca(C7H5O2)2.

Common Uses
The effectiveness of benzoic acid and it’s salts depends on the acidity (pH) of the food. 
Apparently, the most common use of calcium benzoate is in fruit juice1. 
However, I have never found a product that lists it as an ingredient, likely because it is not an approved additive in Canada2.

If anybody knows of a product that specifically lists calcium benzoate as an ingredient, please let us know in the comments, or send me a message, and I’ll list it here.

Health Issues / Side Effects
As far as I’ve been able to discover, the health issues associated with calcium benzoate are similar to the issues described for benzoic acid.

E Number
The E number of calcium benzoate is 213.

Other benzoates include sodium benzoate (E 211), potassium benzoate (E 212), and benzoic acid (E 210).

Notes
While researching this series of posts, I wanted to find out why industry might prefer one form of benzoic acid (or salt) over another form. 
I couldn’t find any conclusive answer except that in many cases the salts are preferred because they are easier to dissolve.

What Is It?
Calcium benzoate is an organic alcohol found in many fruits and teas. 
Calcium benzoate has a hydroxyl group (-OH), while the related compound, Benzoic Acid has a carboxyl group (-COOH). 
Sodium Benzoate, Calcium Benzoate and Potassium Benzoate are salts of Benzoic Acid. 
Calcium benzoate is an ester of Benzyl Alcohol and Benzoic Acid.

Calcium benzoate, salts, and Benzyl Benzoate are used in a wide variety of cosmetics and personal care products, including baby products, bath products, soaps and detergents, eye makeup, blushers, cleansing products, make up products, as well as hair, nail and skin care products.

Why is Calcium benzoate used in cosmetics and personal care products?
The following functions have been reported for these ingredients.
Corrosion inhibitor – Sodium Benzoate
Fragrance ingredient – Benzyl Alcohol, Benzoic Acid, Sodium Benzoate, Benzyl Benzoate
pH adjuster – Benzoic Acid
Preservative – Benzyl Alcohol, Benzoic Acid, Sodium Benzoate, Calcium Benzoate, Potassium Benzoate

Calcium benzoate refers to the calcium salt of benzoic acid. 
Calcium benzoate is used as a preservative (E number 213) in food industry. 
Calcium benzoate is preferentially used more than other benzoic acid salts or its esters in foods due to its better solubility and safety to humans. 
Calcium benzoate is used in soft drinks, fruit juice, concentrates, soy milk, soy sauce and vinegar and most widely used preservative in making bread and other bakery products. 
Calcium benzoate is used as preservative for water based insecticidal composition which can be sprayed as well as in preparation of calcium formate direct sprayable fertilizers. 
Calcium benzoate is used as preservative for mouth wash compositions and in water hardness reducers.

Origin:
Benzoic acid, benzoates and benzoic acid esters are commonly found in most fruits, especially berries. 
Cranberries are a very rich source of benzoic acid. 
In addition to fruits, benzoates occur naturally in mushrooms, cinnamon, cloves and some dairy products (as a result of bacterial fermentation). For commercial purposes, Calcium benzoate is prepared chemically from toluene.


Function & characteristics:
Benzoic acid and benzoates are used as preservatives against both yeasts and bacteria in acidic products. 
They are not very effective against fungi, and ineffective in products with a pH above 5 (slightly acidic or neutral). 
High concentrations lead to a sour taste, which limits the application. 
Benzoates are often preferred, due to better solubility.

Products:
Benzoic acid and benzoates are used in a wide range of acid or slightly acidic products.

Daily intake:
Up to 5 mg/kg body weight.

Side effects:
No side effects in the concentrations used. In some people benzoic acid and benzoates may liberate histamine and thus cause pseudo-allergic reactions.

Dietary restrictions:
None – benzoic acid and benzoates can be consumed by all religious groups, vegans and vegetarians.

The inhibitive effects of calcium benzoate on steel corrosion were studied in sodium nitrate solutions at room temperature. 
Corrosion parameters of the steel/nitrate and steel/benzoate+nitrate interfaces were obtained from polarization curves. 
Adsorption parameters of benzoate on steel in sodium nitrate solutions were determined through changes in the degree of surface coverage by the inhibitor, as a function of concentration, time, and adsorption potential. 
The most likely adsorption configuration of benzoate on iron was envisaged with the help of semiempirical calculations such as extended Hückel calculations. 
A two-dimensional flat configuration was involving at least two metal atoms, one interacting with the phenolic group and the other with the carboxylate moiety. 
The effect of chloride on the corrosion inhibition of benzoate was analyzed by exposing the metal to different chloride solution concentrations, from which corrosion parameters were calculated and compared with those in nitrate solutions.

Definition
Calcium benzoate is a calcium salt of benzoic acid used as a preservative in acidic foods to prevent growth of bacteria and fungi.

Health considerations
Calcium benzoate is considered generally safe at levels present in food. 
When present with ascorbic acid, calcium benzoate may react to form benzene. See: Benzene

May be found in
Soft drinks, fruit juice, pickles, condiments, sauces, salad dressings

What is Calcium Benzoate
Calcium Benzoate is the Calcium sale of Benzoic acid. 
Calcium Benzoate is a standard food preservative used in soy sauce, juice, and vinegar.

Some leading plastics manufacturers includes Calcium Benzoate in their production of plastic food packaging.

As a Feed Additive Ingredient:
Calcium Benzoate could be potentially used as a feed additive. 
Calcium Benzoate Calcium ingredient can serve as a Calcium supplement, while its Benzoate portion could improve pigs’ digestive ability, given that Benzoic acid is a widely used feed additive itself.
