Is Coolant an Irritant?
Understanding Coolant and Its Chemical Composition
Coolant, also known as antifreeze, is a liquid substance used in vehicles to regulate engine temperature and prevent overheating. The most common type of coolant is a mixture of water and ethylene glycol (EG), a colorless, odorless liquid that is highly soluble in water. EG is the primary component responsible for the coolant’s ability to lower the freezing point of water and prevent corrosion.
However, EG is also known to be a skin and eye irritant, as well as a potential toxic substance if ingested in large quantities. The American Conference of Governmental Industrial Hygienists (ACGIH) has established a threshold limit value (TLV) of 200 mg/m3 for EG as a time-weighted average (TWA) for an 8-hour workday, indicating that prolonged exposure to EG can be hazardous to human health.
Other types of coolants, such as propylene glycol (PG) and glycerin, are also used in some applications, but EG remains the most widely used and well-established coolant in the automotive industry.
Chemical Properties of Coolant
- Ethylene Glycol (EG): 95-99% water soluble, highly corrosive, and toxic if ingested.
- Propylene Glycol (PG): 50-70% water soluble, less corrosive than EG, and less toxic if ingested.
- Glycerin: 100% water soluble, non-toxic, and non-corrosive.
The chemical properties of coolant play a crucial role in determining its potential as an irritant. For example, EG’s high water solubility allows it to easily penetrate skin and cause irritation, while PG’s lower water solubility makes it less likely to cause irritation.
Coolant and Skin Irritation
Skin irritation is a common concern when working with coolants, particularly EG. Prolonged exposure to EG can cause redness, itching, and burning sensations on the skin. In severe cases, EG can cause contact dermatitis, a condition characterized by inflammation and blistering of the skin.
The risk of skin irritation is increased when handling coolants in the following situations:
- Direct skin contact: Handling coolants without proper protective gear can lead to skin irritation.
- Prolonged exposure: Working with coolants for extended periods can increase the risk of skin irritation.
- Concentration: Higher concentrations of EG can increase the risk of skin irritation.
Preventing Skin Irritation from Coolant
To prevent skin irritation from coolant, follow these guidelines:
- Wear protective gear: Gloves, long sleeves, and pants can protect the skin from coolant exposure.
- Use a barrier cream: Applying a barrier cream to exposed skin can prevent coolant from penetrating the skin.
- Work in a well-ventilated area: Good ventilation can help reduce the concentration of coolant in the air and prevent skin irritation.
- Follow manufacturer instructions: Always follow the manufacturer’s instructions for handling and using coolants.
Coolant and Eye Irritation
Coolant can also cause eye irritation, particularly EG. Prolonged exposure to EG can cause redness, itching, and burning sensations in the eyes. In severe cases, EG can cause eye damage and even vision loss.
The risk of eye irritation is increased when handling coolants in the following situations:
- Direct eye contact: Handling coolants without proper protective gear can lead to eye irritation.
- Prolonged exposure: Working with coolants for extended periods can increase the risk of eye irritation.
- Concentration: Higher concentrations of EG can increase the risk of eye irritation.
Preventing Eye Irritation from Coolant
To prevent eye irritation from coolant, follow these guidelines:
- Wear protective gear: Safety glasses or goggles can protect the eyes from coolant exposure.
- Use a splash guard: A splash guard can prevent coolant from splashing into the eyes.
- Follow manufacturer instructions: Always follow the manufacturer’s instructions for handling and using coolants.
Coolant and Respiratory Irritation
Coolant can also cause respiratory irritation, particularly EG. Prolonged exposure to EG can cause coughing, wheezing, and shortness of breath. In severe cases, EG can cause respiratory damage and even asthma. (See: Sca Coolant)
The risk of respiratory irritation is increased when handling coolants in the following situations:
- Direct inhalation: Handling coolants without proper ventilation can lead to respiratory irritation.
- Prolonged exposure: Working with coolants for extended periods can increase the risk of respiratory irritation.
- Concentration: Higher concentrations of EG can increase the risk of respiratory irritation.
Preventing Respiratory Irritation from Coolant
To prevent respiratory irritation from coolant, follow these guidelines:
- Work in a well-ventilated area: Good ventilation can help reduce the concentration of coolant in the air and prevent respiratory irritation.
- Use a respirator: A respirator can filter out coolant particles and prevent inhalation.
- Follow manufacturer instructions: Always follow the manufacturer’s instructions for handling and using coolants.
Coolant and Other Health Risks
Coolant can also pose other health risks, including:
- Carcinogenicity: EG has been linked to carcinogenicity, and prolonged exposure may increase the risk of cancer.
- Toxicity: EG can be toxic if ingested in large quantities, and prolonged exposure may increase the risk of toxicity.
- Allergic reactions: Some individuals may be allergic to coolants, and exposure can cause allergic reactions.
Preventing Other Health Risks from Coolant
To prevent other health risks from coolant, follow these guidelines:
- Follow manufacturer instructions: Always follow the manufacturer’s instructions for handling and using coolants.
- Use proper protective gear: Wear protective gear, such as gloves and safety glasses, to prevent skin and eye irritation.
- Work in a well-ventilated area: Good ventilation can help reduce the concentration of coolant in the air and prevent respiratory irritation.
-
Skin irritation: Coolant can cause skin irritation, including redness, itching, and burning sensations.
-
Eye irritation: Coolant can cause eye irritation, including redness, itching, and tearing.
-

Is Coolant an Irritant?
The Basics of Coolant Irritation
Coolant, also known as antifreeze, is a liquid substance used in vehicles to regulate engine temperature. It is typically a mixture of water and ethylene glycol or propylene glycol. While coolant is essential for the proper functioning of an engine, it can also pose health risks if not handled properly.
When coolant comes into contact with skin or mucous membranes, it can cause irritation. This is because the chemicals in coolant, such as ethylene glycol, can be absorbed through the skin and cause systemic toxicity. In addition, the pH level of coolant can be quite high, which can cause skin burns and irritation.
There are several types of coolant available, and some are more irritating than others. For example, ethylene glycol-based coolants are more toxic than propylene glycol-based coolants. However, even propylene glycol-based coolants can cause irritation if not handled properly.

Causes of Coolant Irritation
Coolant irritation can occur in a variety of situations, including:
Prevention and Treatment
To prevent coolant irritation, it is essential to handle coolant properly. This includes wearing protective clothing, such as gloves and a face mask, and using a splash-proof container to store coolant. If coolant comes into contact with the skin or eyes, it is essential to wash the affected area with soap and water immediately. If the irritation persists, seek medical attention.
| Symptoms | Treatment |
|---|---|
| Skin irritation (redness, itching, burning) | Wash affected area with soap and water. Apply a topical cream or ointment to soothe the skin. |
| Eye irritation (redness, itching, tearing) | Flush eyes with water immediately. If irritation persists, seek medical attention. |
