How does Diisobutyl phthalate (DIBP) affect workers’ health?
Nov
Diisobutyl phthalate (DIBP) is a chemical compound common in the manufacturing industry, but few people know about its dangerous impact on the health of workers. This article will help you understand the health risks of exposure to DIBP and how to effectively prevent them.
1. What is Diisobutyl phthalate (DIBP)?
The chemical formula C₁₆H₂₂O₄ represents an organic compound belonging to the phthalate group, which are esters of phthalic acid. This substance is primarily produced to be used as a plasticizer in the plastics industry, helping to increase the flexibility and durability of plastic materials. Diisobutyl phthalate is characterized as being colorless, odorless, and having high viscosity. It is commonly used in the production of materials such as plastics, rubber, and other consumer products, and thus has wide applications in the electronics, automotive, and pharmaceutical industries.
Regarding its molecular structure, this substance has two isobutyl groups linked to a phthalic acid molecule, creating a stable structure. This is why it can persist for a long time in the environment, be easily absorbed through the skin and respiratory system, and cause negative impacts on human health if not properly controlled.

2. What are the sources of Diisobutyl phthalate (DIBP) during production?
During the production process, Diisobutyl phthalate (DIBP) primarily arises from activities using phthalates as plasticizers. DIBP is added to plastic and rubber products to increase their flexibility, pliability, and durability. The plastics manufacturing process, especially in industries producing cables, plastic films, and electronic products, is where DIBP is widely used. When plastic materials containing DIBP are processed, this substance can be released into the environment, mainly through vapor or fine dust, creating opportunities for worker exposure.
In addition, DIBP can also originate from chemical products such as paints, printing inks, and construction materials containing phthalates. In manufacturing plants, processes like mixing, calendering, or extruding plastic can release DIBP into the air or wastewater, making it easy for workers in the production area to be exposed to this substance through respiration or direct skin contact.
3. Industries that use Diisobutyl phthalate (DIBP) in production
Diisobutyl phthalate (DIBP) is widely used in many industries, especially in the production of plastic and rubber materials. Sectors such as the manufacturing of electrical cables, plastic films, and construction materials are major consumers of DIBP. In the plastics industry, DIBP is used as a plasticizer to create products that are flexible, durable, and easy to process. These plastic products can be applied in various fields, from household goods and packaging to electronic devices.
Additionally, the automotive industry also uses DIBP in the production of plastic parts, especially those requiring high flexibility, such as hoses, window seals, or interior decorative details. DIBP is also present in the textile industry, where it helps increase the elasticity and water resistance of fabric materials, and is used in some types of paints and printing inks to improve the quality and durability of the product.
Factories producing construction materials, especially those that manufacture paints, adhesives, and various types of mortars, also use DIBP to create products with high flexibility and adhesion. This chemical is also found in the printing ink industry, where it helps create products with high colorfastness and good adhesion on many types of surfaces. In summary, DIBP is used in a wide range of industries, from plastics, rubber, and textiles to consumer and industrial products.
4. How does Diisobutyl phthalate (DIBP) affect workers?
Long-term exposure to Diisobutyl phthalate (DIBP) can cause serious effects on the health of workers, especially when the substance is absorbed through the respiratory tract, skin, or digestion. One of the main concerns is its potential to cause endocrine disruption. DIBP can affect the body’s hormone system, altering the production and activity of hormones, especially sex hormones. This can lead to reproductive problems, such as reduced fertility or diseases related to sexual physiology.
Furthermore, DIBP can also cause respiratory problems for workers. Inhaling DIBP dust or vapor during production can irritate the respiratory tract, leading to symptoms such as coughing, shortness of breath, and inflammation of the nose and throat. Particularly for those working in environments without good ventilation systems or without using adequate personal protection, the risk of impact on the lungs and respiratory system is even higher.
The effects on the skin cannot be ignored either. DIBP can easily penetrate the skin upon direct contact with products containing this substance, causing skin irritation or allergies, with symptoms like rashes, itching, or dermatitis. If not treated promptly, this condition can become more severe, affecting the long-term health of workers.
Finally, DIBP can also cause some problems related to the nervous system, including headaches, dizziness, and fatigue. These symptoms can be signs of exposure to a large amount of DIBP in the work environment, affecting the overall health of workers over a long period of employment.
5. Permissible safe concentration of Diisobutyl phthalate (DIBP) for human exposure
The permissible safe concentration of Diisobutyl phthalate (DIBP) for human exposure depends on the regulations and standards of each country as well as international health organizations. Agencies such as the World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA) have established safe concentration limits for DIBP in the air and the workplace to protect workers’ health.
According to studies, the safe level of DIBP is often assessed through indicators such as the maximum permissible concentration in the workplace air (TLV – Threshold Limit Value) and the level of long-term exposure that does not cause adverse health effects. Specifically, guidelines permit a DIBP concentration in the workplace air of about 5 mg/m³ for an hour of work in a well-ventilated environment. However, this exposure level can still vary depending on factors such as exposure duration, working conditions, and individual sensitivity.
In the case of skin contact with DIBP, the safe concentration level also needs to be strictly controlled, especially in industries that use this chemical at high levels.
On a basic level, when working in an industrial environment, it is important to adhere to safety standards and limit exposure to Diisobutyl phthalate (DIBP). Organizations such as the Occupational Safety and Health Administration (OSHA) in the United States provide guidelines and safety principles to protect workers from the negative impacts of chemical substances.
6. Measures to mitigate the effects of Diisobutyl phthalate (DIBP) on workers’ health
To mitigate the effects of Diisobutyl phthalate (DIBP) on workers’ health, a series of prevention and protection measures must be implemented. First and foremost, compliance with occupational safety regulations and DIBP concentration limits in the air is very important. Factories and production facilities need to install good ventilation systems to reduce DIBP concentrations in the air, helping to protect workers from inhaling toxic DIBP gas or vapor. Maintaining a well-ventilated and clean working environment also helps limit the spread of this chemical.
Besides, the use of personal protective equipment such as gloves, chemical-resistant masks, and protective clothing is extremely necessary. This equipment not only helps reduce direct contact with DIBP through the skin but also protects the respiratory system of workers from the intrusion of toxic substances. Especially in industries that use DIBP at high levels, the application of personal protective measures must be checked and ensured to always meet safety standards.
Training and raising awareness for workers is also a key factor in minimizing health risks. Occupational safety training courses should be held periodically to help workers understand the dangers of DIBP and how to prevent them, as well as how to properly use personal protective equipment. In addition, companies should also implement regular health check-up programs for workers to detect early symptoms related to DIBP exposure.
Finally, replacing DIBP with safer plasticizers, if possible, will contribute to minimizing health risks for workers. Using less toxic and environmentally friendly alternatives not only protects workers’ health but also reduces the adverse impact on the long-term working environment.
Occupational safety training: Workers need to be trained and educated about the risks and safety measures when working with this type of chemical. This training should be provided periodically and regularly to ensure understanding and proper adherence to safety rules.
Periodically conduct occupational environmental monitoring in factories and enterprises, collecting and analyzing harmful factors for workers, thereby adjusting to reduce hazard levels to prevent occupational diseases for them.
