Benzoic acid has anti-inflammatory properties that can help to soothe irritated or inflamed skin. This makes it a beneficial ingredient in products designed to calm redness, itching, and inflammation associated with various skin conditions, such as eczema and psoriasis.
Benzoic acid can also be beneficial for maintaining scalp health. By preventing the growth of bacteria and fungi on the scalp, benzoic acid can help to alleviate dandruff and other common scalp issues. This makes it a valuable addition to shampoos and other hair care products designed to promote a healthy scalp environment.
Be sure to use benzoic acid at the appropriate concentration for your specific product. In general, it's recommended to use benzoic acid at a concentration of 0.1% to 0.5% in your formulations, depending on the intended use and desired effect. It's crucial not to exceed the recommended concentration, as higher amounts of benzoic acid can potentially cause skin irritation or other adverse effects.
Ensure that benzoic acid is compatible with the other ingredients in your formulation. It is soluble in water and alcohol, but not in oil. Additionally, benzoic acid is most effective as a preservative in products with a pH of 4.5 or lower. Consider conducting compatibility tests to ensure that your finished product maintains its desired texture, appearance, and performance.
As with any ingredient, it's essential to follow safety precautions when handling benzoic acid. Wear protective gloves, a mask, and eye protection to avoid contact with your skin, eyes, or respiratory system. Keep benzoic acid out of reach of children and pets, and store it in a cool, dry place away from food and beverages.
When incorporating benzoic acid into your personal care products, make sure to comply with all relevant regulations and guidelines. In the United States, the FDA has approved the use of benzoic acid as a preservative in cosmetics and personal care products at concentrations of up to 0.5%. Be sure to familiarize yourself with the specific regulations in your region and adhere to them accordingly.
Benzoic acid is a versatile ingredient that can provide numerous benefits when used in soap making, cosmetics, skin, and hair care products. Its antimicrobial, anti-inflammatory, and pH-adjusting properties make it a valuable addition to a wide range of formulations. By following the recommendations provided in this product description and adhering to safety and regulatory guidelines, you can safely and effectively incorporate benzoic acid into your personal care routine and enjoy its many advantages.
Benzoic acid, the simplest benzene-based carboxylic acid, has been known since the 16th century. One of its discoverers was the legendary clairvoyant Nostradamus. Its most common natural source is gum benzoin, a resin found in the bark of trees of the genus Styrax.
Most benzoic acid produced today is synthetic. Its first industrial synthesis was the hydrolysis of benzotrichloride to calcium benzoate, followed by acidification. This method has been completely displaced by the air oxidation of toluene, which avoids the problem of product contamination with chlorinated byproducts.
Many processed foods contain benzoic acid or one of its salts as a preservative. The acid inhibits the growth of bacteria, molds, and yeasts; it works best when the food has an acidic pH value. Benzoic acid also is often found in topical antifungal preparations.
(a) Benzoic acid is the chemical benzenecarboxylic acid (C7H6O2), occurring in nature in free and combined forms. Among the foods in which benzoic acid occurs naturally are cranberries, prunes, plums, cinnamon, ripe cloves, and most berries. Benzoic acid is manufactured by treating molten phthalic anhydride with steam in the presence of a zinc oxide catalyst, by the hydrolysis of benzotrichloride, or by the oxidation of toluene with nitric acid or sodium bichromate or with air in the presence of a transition metal salt catalyst.
Atropine , hyoscyamine , methenamine , methylene blue, phenyl salicylate , and benzoic acid combination medicine is an anticholinergic, anti-infective, and analgesic. It is given by mouth to help relieve the discomfort caused by urinary tract infections; however, it will not cure the infection itself. This combination medicine may also be used for other conditions as determined by your doctor.
The researchers found that optimized conditions require a PS sample in acetone exposed to LED light in an oxygen-rich environment, using an iron chloride catalyst for 20 hours. In the optimized process, PS broke down to 23% benzoic acid. Other products included smaller plastic molecules that can be repurposed in other ways.
Benzoic acid is a mono-functional, aromatic acid, which is widely used as a building block for the synthesis of alkyd resins. When used as a component of alkyd resins, it improves gloss, hardness and chemical resistance.
Benzoic acid occurs naturally in many plants and serves as an intermediate in the biosynthesis of many secondary metabolites. Salts of benzoic acid are used as food preservatives. Benzoic acid is an important precursor for the industrial synthesis of many other organic substances. The salts and esters of benzoic acid are known as benzoates /ˈbɛnzoʊ.eɪt/.
Benzoic acid was discovered in the sixteenth century. The dry distillation of gum benzoin was first described by Nostradamus (1556), and then by Alexius Pedemontanus (1560) and Blaise de Vigenère (1596).
Benzoic acid is produced commercially by partial oxidation of toluene with oxygen. The process is catalyzed by cobalt or manganese naphthenates. The process uses abundant materials, and proceeds in high yield.
The first industrial process involved the reaction of benzotrichloride (trichloromethyl benzene) with calcium hydroxide in water, using iron or iron salts as catalyst. The resulting calcium benzoate is converted to benzoic acid with hydrochloric acid. The product contains significant amounts of chlorinated benzoic acid derivatives. For this reason, benzoic acid for human consumption was obtained by dry distillation of gum benzoin. Food-grade benzoic acid is now produced synthetically.
Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic solvents for the recrystallization makes this experiment particularly safe. This process usually gives a yield of around 65%.
Benzoate plasticizers, such as the glycol-, diethyleneglycol-, and triethyleneglycol esters, are obtained by transesterification of methyl benzoate with the corresponding diol. These plasticizers, which are used similarly to those derived from terephthalic acid ester, represent alternatives to phthalates.
Benzoic acid and its salts are used as food preservatives, represented by the E numbers E210, E211, E212, and E213. Benzoic acid inhibits the growth of mold, yeast and some bacteria. It is either added directly or created from reactions with its sodium, potassium, or calcium salt. The mechanism starts with the absorption of benzoic acid into the cell. If the intracellular pH changes to 5 or lower, the anaerobic fermentation of glucose through phosphofructokinase is decreased by 95%. The efficacy of benzoic acid and benzoate is
