Tert-butyl peroxy isobutyrate (>80%) (C8H16O3) is a common chemical in industrial production, but it poses many potential risks to workers’ health. This article will analyze the effects of this substance on the body, potential risks, and effective protective measures to help ensure a safer working environment.
1. What is Tert-butyl peroxy isobutyrate (>80%)?
Tert-butyl peroxy isobutyrate (>80%), with the chemical formula C8H16O3, is an organic compound belonging to the peroxyester group, widely used in industry as a catalyst, free-radical generator, and initiator in the production of polymers and plastics. This compound exists as a transparent liquid, has low volatility, and is easily decomposed by heat or light, releasing free radicals to promote chemical reactions.
The chemical structure of Tert-butyl peroxy isobutyrate includes a peroxy group (-O-O-) linked to an isobutyrate branch and a tert-butyl group, which gives it its characteristic chemical properties. Thanks to its ability to efficiently generate free radicals, this substance plays a crucial role in accelerating the polymerization reaction rate, helping to improve the efficiency and quality of the final product.
However, due to its easily decomposable and exothermic nature, Tert-butyl peroxy isobutyrate also poses safety risks if not stored and used correctly. Therefore, a clear understanding of the properties and applications of this substance is the first important step to ensure its safe and effective use in an industrial environment.

2. Where does Tert-butyl peroxy isobutyrate (>80%) originate from in the production process?
This substance is primarily generated during polymer production, especially in the plastics and rubber industries. In polymerization processes, particularly reactions that require free radicals to activate polymer chains, this substance is used as an initiator to promote thermal polymerization reactions. It can also be created from reactions between peroxy compounds and organic acid groups, which are typically carried out under high temperature and pressure conditions.
The production of Tert-butyl peroxy isobutyrate can occur in chemical plants or plastic manufacturing facilities where catalysts or initiators like peroxyesters are formulated and used in polymerization reactions.

3. Industries that use Tert-butyl peroxy isobutyrate (>80%) in production
This substance is widely used in the plastic and rubber manufacturing industries, especially in the polymerization process to create materials with special properties. In the plastics industry, it plays an important role in initiating polymerization reactions for products such as PVC plastic, molded plastics, and composite materials. Additionally, in the rubber industry, this substance is also used to manufacture synthetic rubber products and elastic materials, thanks to its ability to generate free radicals and promote necessary chemical reactions.
Tert-butyl peroxy isobutyrate is also applied in the paint and coatings industry, where it is used to enhance the reaction speed of paint compounds, making the paint dry faster and helping to increase the durability of the coating. Other industries such as the manufacturing of plastics, building materials, and electronic products may also use this substance to create special materials that require heat resistance and high durability.
4. How does Tert-butyl peroxy isobutyrate (>80%) affect workers?
When exposed to this substance, workers may experience negative health effects due to its chemical properties. This substance is volatile and can cause irritation to the skin, eyes, and respiratory system. If in direct contact, especially in a poorly ventilated work environment or without personal protective equipment, workers may suffer from dermatitis, red eyes, or difficulty breathing. These symptoms are often due to the irritation from the peroxy components in the compound.
If exposure is long-term or its vapors are inhaled in the workplace, it can cause more serious problems, such as lung damage or issues with the nervous system. In particular, when inhaling large amounts of vapor or dust from Tert-butyl peroxy isobutyrate, workers may experience symptoms like dizziness, nausea, or even loss of consciousness in severe cases.
Additionally, this substance can increase the risk of cancer if workers are exposed to it over a long period under poorly controlled conditions.
5. What is the permissible safe concentration of Tert-butyl peroxy isobutyrate (>80%) for human exposure?
The permissible safe concentration of Tert-butyl peroxy isobutyrate (>80%) for human exposure depends on the occupational safety regulations issued by competent authorities and health organizations. According to safety standards, the maximum concentration of this substance in the workplace air must not exceed the permissible limit, which is usually calculated in parts per million (ppm) or milligrams per cubic meter of air (mg/m³).
In many countries, the concentration of Tert-butyl peroxy isobutyrate in the workplace air is typically limited to a low level to ensure the health of workers.

Basically, when working in an industrial environment, it is important to comply with safety standards and limit exposure to Tert-butyl peroxy isobutyrate (>80%). 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 effects of chemical substances.
6. Measures to mitigate the health effects of Tert-butyl peroxy isobutyrate (>80%) on workers
To minimize the health effects of this substance on workers, strict preventive and protective measures must be implemented in the workplace. One of the most important measures is to ensure good ventilation in production areas where this substance is present. An effective ventilation system will help reduce the concentration of the chemical in the air, thereby limiting workers’ exposure to harmful chemical vapors.
In addition, workers must use adequate personal protective equipment such as masks, gloves, safety glasses, and protective clothing to avoid direct contact with this substance. This protective equipment plays a crucial role in protecting the skin, eyes, and respiratory system of workers from harmful effects when working in an environment where Tert-butyl peroxy isobutyrate is present.
Furthermore, training workers on the potential risks of chemical exposure and the proper use of personal protective equipment is also an indispensable factor. Employees need to be specifically instructed on safety measures, correct work procedures, and how to handle incidents. At the same time, production facilities need to regularly check the chemical concentration in the air and implement measures to reduce concentrations that exceed safe levels.
Finally, full compliance with occupational safety and industrial hygiene regulations is a necessary condition to protect workers’ health, minimize risks, and prevent occupational diseases related to this chemical.
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 organize occupational environment monitoring in factories and enterprises, collect and analyze factors harmful to workers, and from there, adjust to reduce hazard levels to prevent occupational diseases for them.
