What is Liquid Paraffin?

Liquid paraffin is a highly refined, colorless, odorless mineral oil derived from petroleum distillates. It is composed primarily of saturated hydrocarbons and is chemically stable, non-reactive, and resistant to oxidation.

Because of its inert nature, it is widely used in:

• Cosmetics

• Medical ointments

• Baby oils

• Industrial lubrication

• Plastic manufacturing

• Food-grade coatings

• Textile treatment

• Polishing and moisture-resistant products

However, it is important to understand that not all liquid paraffin is the same. Different grades have significantly different safety profiles.

What are the hazards of paraffin liquid?

Skin Irritation

It can cause skin irritation in some individuals. Prolonged exposure may lead to redness, itching, and dryness.

• Prevention: Use protective gloves and limit skin contact.
• Treatment: Wash the affected area with soap and water. Apply a soothing cream if necessary.

Respiratory Issues

Inhaling its fumes can cause respiratory problems. Symptoms may include coughing, shortness of breath, and chest discomfort.

• Prevention: Ensure proper ventilation when using it. Use a mask if necessary.
• Treatment: Move to fresh air and seek medical attention if symptoms persist.

Eye Irritation

Accidental contact with it can irritate the eyes. Symptoms include redness, watering, and a burning sensation.

• Prevention: Wear safety goggles when handling it.
• Treatment: Rinse the eyes with clean water for at least 15 minutes. Seek medical advice if irritation continues.

Ingestion Hazards

Ingesting liquid paraffin can lead to digestive issues. Symptoms may include nausea, vomiting, and diarrhoea.

• Prevention: Store it away from food and drink. Use clear labelling to avoid accidental ingestion.
• Treatment: Do not induce vomiting. Seek immediate medical assistance.

Grades of Liquid Paraffin and Their Safety Differences

1. Pharmaceutical-Grade Liquid Paraffin

This is the highest purity level. It meets strict standards such as:

• BP (British Pharmacopoeia)

• USP (United States Pharmacopeia)

• EP (European Pharmacopoeia)

Uses include:

• Laxatives

• Baby lotions

• Medical creams and ointments

• Moisturizers

This grade is safe for skin contact and oral intake (as prescribed).

2. Cosmetic-Grade Liquid Paraffin

Slightly lower purity than pharmaceutical grade but still safe for external use in:

• Creams

• Lotions

• Lip care

• Hair oils

• Makeup removers

It has strict limits on aromatic hydrocarbons and toxic impurities.

Moisturizers

Liquid paraffin is a key ingredient in many moisturizers. It helps to lock in moisture and keep the skin hydrated.

Makeup Removers

Due to its gentle properties, liquid paraffin is used in makeup removers. It effectively dissolves makeup without irritating the skin.

Hair Care Products

It is found in various hair care products. It adds shine and helps to tame frizz, improving hair appearance.

3. Industrial-Grade Liquid Paraffin

This grade may contain more impurities and is used in:

• Lubrication

• Plastic processing

• Metalworking

• Textile manufacturing

• Heavy-duty coatings

Industrial-grade paraffin is NOT safe for skin, inhalation, or ingestion.

This distinction is critical when addressing whether liquid paraffin is hazardous.

Lubricants

It is used as a lubricant in machinery and equipment. It reduces friction and wear, prolonging the lifespan of components.

Coolants

In industrial processes, liquid paraffin acts as a coolant. It helps to maintain optimal temperatures and prevent overheating.

Hydraulic Fluids

Liquid paraffin is used in hydraulic systems. Its properties make it suitable for transmitting power and ensuring smooth operation.

Safe Handling Practices

Personal Protective Equipment (PPE)

Always wear appropriate PPE when handling liquid paraffin. This includes gloves, safety goggles, and protective clothing.

Proper Storage

Store it in a cool, well-ventilated area. Ensure containers are tightly sealed to prevent leaks and contamination.

Labeling and Signage

Clearly label containers with the contents and any hazard warnings. Use appropriate signage in storage and handling areas.

Ventilation

Ensure good ventilation in areas where liquid paraffin is used. This helps to disperse any fumes and reduce inhalation risks.

Is Liquid Paraffin Hazardous? Understanding Its Safety Profile

Liquid paraffin is often categorized as “low toxicity”, but that does not mean it is risk-free. Its hazards depend on:

• Exposure route

• Duration

• Concentration

• Grade of oil

• Environment of use

Let’s explore each key risk area.

Fire and Flammability Hazards

Liquid paraffin is combustible but not highly flammable.

Key facts:

• It does not vaporize easily at room temperature.

• It requires a high temperature to ignite.

• Industrial environments with heat sources increase risk.

Flash Point: 150°C–220°C depending on grade.

This means liquid paraffin can catch fire when heated significantly above normal working temperatures.

Emergency response recommendations:

• Use foam, dry chemical, or CO₂ extinguishers.

• Do not use water jets—they can spread burning oil.

Although the fire risk is moderate, it becomes a concern in:

• Textile mills

• Machinery lubrication processes

• Plastic manufacturing

• Bulk storage facilities

Inhalation Hazards: A Key Area of Concern

Liquid paraffin is generally safe on the skin, but inhaling aerosolized or mist forms is hazardous.

Potential risks include:

• Lung irritation

• Chemical pneumonitis

• Lipid pneumonia

• Chronic respiratory issues

These issues occur primarily when:

• Spraying or fogging paraffin oils

• Operating around paraffin-based mists

• Using high-temperature machinery that vaporizes oil

• Poorly ventilated industrial spaces

For everyday users of cosmetics or lotions, these risks do not apply.

Skin Exposure: Generally Safe, But With Considerations

Pharmaceutical and cosmetic-grade paraffin is widely used in skincare because it is:

• Non-irritating

• Hypoallergenic

• Inert

• Moisture-locking

However, excessive or improper use can:

• Block pores

• Cause acne or folliculitis

• Create a greasy barrier

Industrial-grade paraffin should never come into direct skin contact because impurities may irritate the skin.

Ingestion: Only Pharmaceutical Grade Is Safe

Some medical formulations use liquid paraffin as a laxative.

ONLY pharmaceutical-grade paraffin is safe for ingestion.

Ingesting industrial-grade paraffin can lead to:

• Gastrointestinal distress

• Toxicity from impurities

• Lipid aspiration in severe cases

Furthermore, swallowing paraffin and accidentally inhaling it into the lungs can cause:

• Aspiration pneumonia

• Severe inflammation

• Hospitalization

Always follow medical guidance when consuming paraffin-based products.

Environmental Hazards

Liquid paraffin is derived from petroleum, meaning it has inherent environmental impacts.

Potential issues include:

• Soil contamination

• Harm to aquatic life

• Long-term persistence in ecosystems

• Slow biodegradation

Industrial spills must be managed with:

• Absorbent materials

• Containment booms

• Hazardous waste disposal

• Professional cleanup teams

Small household uses, however, pose negligible environmental risks.

Occupational Exposure Risks

Industrial workers may face the highest potential risks from liquid paraffin exposure.

Occupational hazards include:

• Respiratory issues from oil mists

• Skin irritation from prolonged contact

• Slips on paraffin-coated floors

• Fire risks near heated equipment

Recommended safety measures:

• Protective gloves and clothing

• Proper ventilation systems

• Eye protection

• Respiratory masks (when needed)

• Spill control procedures

Workplaces using paraffin must follow OSHA and local HSE regulations.
