Iodine is a nonmetallic element and the heaviest halogen in the periodic table. It is found in small amounts in many natural sources, including brines and seaweeds. It is also used in analytical chemistry and photography. The radioactive isotope I-131, which has a half-life of eight days, is used in medicine and other applications due to its long-lasting effect. Iodine is a dark crystalline solid that can change to deep violet when heated and can produce a pungent vapor.

Maintaining optimal mental and physical development is a critical benefit of consuming iodine. Iodine deficiency can lead to a range of disabilities and disorders, including goiter, hypothyroidism, cretinism, abortion, stillbirth, mental retardation, and psychomotor defects. These consequences are often invisible and irreversible, but they are entirely preventable with adequate iodine intake.

Iodine deficiency is the leading cause of preventable brain damage globally. In areas where the soil lacks iodine, children have been found to have an average of 13.5 IQ points less than those in iodine-sufficient areas. Ensuring adequate iodine intake is crucial for individuals of all ages.

  • Chile and Japan are leading producers of iodine, together accounting for more than 90% of global production.
  • The top five manufacturing companies in the world account for 60% to 65% market share in 2023.
  • The market is estimated to create an absolute incremental $ opportunity of US$ 3.5 billion from 2023 to 2033.

Sales of iodine are being driven by increasing demand for alcohols, ketones, and other organic acids due to their widespread use in the production of various chemicals and products. Overall, iodine is a crucial element with numerous applications in various industries, including medicine, chemical production, and photography. It is also essential for human health, and its deficiency can lead to significant health problems.

What are the Factors Responsible for High Sales of Iodine?

“Extensive Utilization of Iodine as Contrast Imaging Agent in Radiography”

Iodine is used as a contrast agent to facilitate radiographic modalities. Iodine's high atomic number and density make it the perfect material for this use because its presence in the body can aid in enhancing the contrast between tissues, organs, and blood vessels with similar X-ray densities. Iodinated contrast media can be either water-soluble or oil-based. Water-soluble media are widely preferred due to their rapid absorption and can serve as a substitute for barium sulfate in gastrointestinal studies.

Due to potential harm to certain individuals, non-ionic iodinated contrast media is extensively utilized as a safer alternative to ionic contrast media. Iodinated contrast agents temporarily change the way X-rays or other imaging tools interact with the human body. Iodinated contrast agents are usually injected into a blood vessel or within the disk/fluid spaces of the spine. As a result of its wide use in the healthcare sector for medical imaging purposes, demand for iodine as a contrast agent is expected to increase significantly over the forecast period.

"Environmental Stability of Iodine Contributing to Widespread Adoption in Chemical Industries”

Iodine is widely used as a catalyst in various chemical reactions, including the synthesis of ketones and the esterification of acids. In these reactions, iodine is used in its molecular form as a catalyst. Iodine is also used in the acylation of alcohols, allylation of aldehydes, cycloaddition reactions, and oxidization of benzylic alcohols. These reactions are critical in the production of various chemicals, such as acetic acid, which are used in the chemical industry for the production of other chemicals and products.

Chemical industries use iodine for conducting catalytic reactions because of its environmentally stable properties and cost-effectiveness. Unlike transition metals, iodine does not release toxic compounds during the catalytic process, making it a safer and more environmentally friendly alternative. Growing demand for organic acids is driving the growth of the market, and its continued adoption by chemical industries is expected to contribute to this growth in the future.

What is Restraining the Demand Growth for Iodine to Some Extent?

“Potential Toxicity Associated with Iodine and Periodic Fluctuations in Prices”

Increasing availability of iodine substitutes such as bromine, chlorine, antibiotics, and boron for various applications, particularly in biocides, colorants, and inks, is expected to hinder the demand for iodine globally.

Price volatility can have a negative impact on sales of iodine in terms of value. Iodine prices are subject to change every year and quarter, which can affect the profitability of manufacturers in the future.

The potential toxicity associated with the consumption of iodine, lack of awareness about the importance of iodine in human nutrition, especially in developing economies, and limited investments in mining and extraction activities owing to the global economic slowdown are also significant factors hindering the growth of the market.
