Citric acid

(77-92-9)
1. Citric acid is a weak organic acid that is known as a commodity chemical, as more than a million tonnes are produced every year by mycological fermentation on an industrial scale using crude sugar solutions, such as molasses and strains of Aspergillus niger. Citric acid is widely distributed in plants and in animal tissues and fluids and exist in greater than grace amounts in variety of fruits and vegetables, most notably in citrus fruits such as lemon and limes. Citric acid is mainly used as

Oxalic acid

(144-62-7)
Oxalic acid gets its name from the fact that early researchers isolated it from flowering plants of the genus Oxalis. It is the simplest dicarboxylic acid, a colorless monoclinic flaky or prismatic crystal or white powder, which dissolves in water to form a colorless solution. Oxalic acid produced by oxidation is odorless, while synthetic oxalic acid has a taste. It sublimates at 150-160°C and can weather in hot dry air. 1 g of oxalic acid dissolves in 7 mL of water, 2 mL of boiling water, 2.5 mL of ethanol, 1.8 mL of boiling ethanol, 100 mL of ether, and 5.5 mL of glycerol, and is insoluble in benzene, chloroform, and petroleum ether. The pH of a 0.1 mol/L solution is 1.3, the chemical formula is H₂C₂O₄, the relative density is 1.653, and the melting point is 189.5°C. It is present in many foods and is a naturally occurring compound in many fruits, vegetables, nuts, and whole grains. Although small amounts of oxalic acid are harmless, this compound can inhibit the absorption of other important nutrients. Excessive intake of oxalic acid or prolonged skin contact can be dangerous. It easily forms calcium oxalate with calcium ions in the human body, leading to kidney stones, so oxalic acid is often considered an antagonist of mineral absorption and utilization.

Ethylenediaminetetraacetic acid

(60-00-4)
Ethylenediaminetetraacetate (EDTA) is a sequestrant and chelating agent that functions in water but not in fats and oils. It is used to control the reaction of trace metals with some organic and inorganic components to prevent deterioration of color, texture, and development of precipitates, as well as to prevent oxidation which results in rancidity. The reactive sites of the metal ions are blocked, which prevents their normal reactions. The most common interfering metal ions in food products ar

Chelating are substances that help the stability and performance of cosmetic products. The substance forms complexes with metal ions, which may affect the stability and/or appearance of cosmetics. According to their origin, chelating agents can be classified into natural compounds and synthetic chemicals. Natural chelating agents, such as citric acid or EDTA derived from plant sources. Synthetic chelating agents mainly include DTPA or HEDTA. According to their chemical structure, chelating agents are categorized as amino polycarboxylates, phosphonates, or hydroxycarboxylic acids. "Chelating" on ECHEMl mainly supplies raw materials for chelating agents in cosmetic.

Frequently Asked Questions

What are chelating agents and how do they work?

Chelating agents are chemical compounds that form multiple bonds with metal ions, creating stable, water-soluble complexes. This process, known as chelation, effectively deactivates or removes metal ions from solutions. Chelating agents are widely used in industries such as pharmaceuticals, agriculture, water treatment, and food processing to control metal ion activity, prevent oxidation, and improve product stability.

What are common types of chelating agents used in industrial applications?

Common chelating agents include EDTA (ethylenediaminetetraacetic acid), DTPA (diethylenetriaminepentaacetic acid), NTA (nitrilotriacetic acid), and citric acid. Each has specific strengths depending on pH, metal ion type, and environmental considerations. For example, EDTA is highly effective across a broad pH range, while citric acid is preferred in eco-friendly or food-grade applications due to its biodegradability.

How do I choose the right chelating agent for my application?

Selecting the appropriate chelating agent depends on several factors:1. The target metal ion(s) you need to bind.2. The pH and temperature of your system.3. Regulatory and environmental requirements—e.g., biodegradability for wastewater discharge.4. Compatibility with other ingredients in your formulation.Consulting technical data sheets and supplier expertise can help ensure optimal performance and compliance.

Are chelating agents safe for use in food and pharmaceutical products?

Yes, certain chelating agents like citric acid, calcium disodium EDTA, and sodium citrate are approved by regulatory bodies such as the FDA and EFSA for use in food and pharmaceuticals. They help preserve color, flavor, and shelf life by sequestering metal catalysts that promote spoilage. However, usage levels must comply with established safety limits to ensure consumer safety.

What role do chelating agents play in water treatment?

In water treatment, chelating agents prevent scale formation and corrosion by binding calcium, magnesium, iron, and other metal ions that contribute to hardness and oxidative damage. They also enhance the efficiency of detergents and disinfectants by keeping metal ions in solution. Chelants like EDTA and phosphonates are commonly used in cooling towers, boilers, and municipal water systems to maintain equipment integrity and water quality.
