Applications of Iodine

Iodine is widely used in the pharmaceutical industry, human nutrition, LED/LCD screens, and biocides.

Iodine is an essential chemical element with multiple applications in the pharmaceutical industry, human nutrition, technology, and industrial processes. Thanks to its chemical properties, it is used in various industrial and service sectors.

• Iodine-based biocides are used in paints, adhesives, wood, and metallurgy.
• Iodine in polarizing films is essential for LCD and LED screens.
• Human nutrition requires Iodine for proper thyroid function and to prevent diseases such as goiter.
• In the pharmaceutical industry, Iodine is the basis for X-ray contrast media, antiseptics, and drug synthesis.

Iodine-based biocides

Iodine-based biocides are used in industrial applications such as:

• Paints and adhesives (to prevent the proliferation of fungi and bacteria).
• Wood treatment (protection against pests and degradation).
• Metallurgical fluids (microbial control in industrial systems).

Iodine ensures a broad-spectrum antimicrobial effect, making it essential in processes where health safety and material preservation are required.

Iodine in LCD/LED polarizing film

LCD and LED screens rely on polarizing film containing liquid crystal solutions.

Iodine is a key component in these films, as it improves polarization capacity, enabling clear and efficient image display on electronic devices such as:

• Televisions
• Monitors
• Mobile phones
• Digital panels

Importance of Iodine in human nutrition

Iodine is a micronutrient essential for the proper functioning of the body, especially the thyroid gland, which regulates metabolism.

Iodine deficiency can cause:

• Goiter (enlargement of the thyroid).
• Hypothyroidism (malfunction of the thyroid).
• Intellectual disability and fetal growth disorders during pregnancy.

To prevent these diseases, table salt is iodized in most countries, which is one of the most effective public health strategies in the world.

Iodine in the pharmaceutical industry and medicine

Iodine is widely used in the pharmaceutical and medical industries, mainly in:

• Contrast media for X-ray scans: it allows soft tissues and blood vessels to be visualized in medical studies.
• Antiseptics: used in surgical and hospital disinfection.
• Catalyst and chemical reagent in the synthesis of numerous drugs, including:

Antibiotics
Corticosteroids
Cardiovascular drugs

This makes Iodine a strategic resource for modern medicine and biomedical research.
