Top Global Citric Acid Supplier

Citric Acid is the most common acids in the world, it is naturally concentrated in a variety of fruits and vegetables and most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; as with most organic acids, citric acid is a weak acid, with a pH level between 3 and 6. It is a weak organic acid that has the molecular formula C6H8O7. It occurs naturally in citrus fruits.

Citric Acid can be obtained as an anhydrous (water-free) form or as a monohydrate. The anhydrous form crystallizes from hot water, while the monohydrate forms when citric acid is crystallized from cold water. The monohydrate can be converted to the anhydrous form at about 78 °C. Citric acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of ethanol) at 15 °C. Citric acid can be esterified at one or more of its three carboxylic acid groups to form any of a variety of mono-, di-, tri-, and mixed esters. More than 50% of Citric Acid production, used as an acidity regulator in beverages, some 20% in other food applications, 20% for detergent applications, and 10% for applications other than food, such as cosmetics, pharmaceuticals, and in the chemical industry.

Citric Acid

No substantial difference between Citric Acid Anhydrous (CAA) and Citric Acid Monohydrate (CAM), just CAM has the crystallization water which can be dissolved without any difference from normal water.

Uses & Application

Citric Acid, commonly used as a food additive as a natural flavouring and a preservative, agent in food and beverage industry, it is also used as antioxidant, plasticizer and detergent in chemical, cosmetics and cleaning industries.

Food Flavouring and Preservative

Citric acid can be added to processed and packaged foods and drinks such as ice cream, sorbets, sodas, wine and canned and jarred foods, as a preservative, an emulsifying agent and as a sour flavourings. Citric acid is added to many canned and jarred foods to help prevent botulism.

Cosmetics and Personal Care Products

As an ingredient in personal care products, citric acid can help to brighten skin, correct dark spots and minimize fine lines. Products containing citric acid can be formulated for use near the eyes, lips, mouth and nasal passages, as well as for safe application to babies’ skin. Citric acid and its salts may also be used in hairsprays, and deodorant and body sprays. Sodium citrate, a salt of citric acid, is used in lipstick, soap, and in detergent. Citric acid and its salts can be used to preserve cosmetics and personal care products, and to help adjust their pH level.

Pharmaceutical and Drugs and Medical uses

Citric acid is used to help kill harmful bacteria, as well as infections on the surface of the skin that can be common in people with diabetes, the elderly and people who smoke. Citric acid also can be combined with sodium citrate and potassium citrate to lower acid levels in the urine to help prevent gout attacks.

Antioxidant

Antioxidants, which are derived from citric acid, can help keep food edible over a longer period of time. For example, sprinkling lemon juice, which contains citric acid, over apples or bananas can help prevent them from turning brown. Ascorbic acid, better known as Vitamin C, is also found in citric acid and is often used to help protect and preserve soft drinks and meats.

Cleaning Products

Citric acid may be added to commercial cleaning products, as it can help remove hard water build-up on dishes and glassware. It also can be used to remove coffee and tea stains, yellowing/browning discolorations and water and urine stains. Some commercial products that contain citric acid are water-based and can cause corrosion on metals. To minimize and prevent rust, dry the metal after cleaning it.
